On Thursday I'll be interviewing an evolutionary anthropologist on metabolism. He's researched the physiology of humans, chimpanzees and apes to learn how diet, lifestyle, exercise and environment affect metabolism and health. We'll get into energy, calories, weight management, disease, fad diet flimflam, etc. Post your questions in the comments!

Comments

Melissa Wise

Please explain why my 20lb dog has the metabolism of an Olympic athlete, yet myself as a petite woman can barely look at a pizza without gaining weight. I.e. why do some small animals need such a high metabolism and huge tortoises have super slow metabolisms?

Rebecca Roehm

Can we do anything to counteract the effects of perimenopause/menopause on metabolism? There is so much flim flam on the internet I don’t know what to believe!

Sarah Jo

What’s the physiology behind not eating enough for extended periods of time causing digestive problems? Did my stomach really forget how to digest food when I wasn’t able to eat enough?

Heidi Wright

I just want to know how much did I inherit from my family and how much can I influence from my life choices.

Sarah Jo

Also why do I gain weight when I don’t eat enough after my immune system ate my thyroid?

Olga

Can you actually speed up your metabolism or is that a myth? Also, if you can and let’s say you do - does that metabolism speed get passed on to your kids?

Kimisha Cassidy

Why do I go into a food coma on such a regular basis? It's a running joke amongst my friends and family - am I just worse at hiding my post-meal sleepiness than everyone else?

Madelyn Dunkle

Do medicines influence metabolism (looking at you SSRIs) and WHY?!?!

Annmarie Everhart

What can I do to speed up a naturally slower metabolism?

Jo B

Is metabolism rate something you inherit/runs in the family/genetics and is there anything you can or should do to alter it?

Isis

Is there a relation between being bloated and your metabolism?

Daniella Napolitano

Is metabolism and being cold all the time linked together somehow? I'm a perpetually cold individual and someone once told me it may have to do with metabolism but that could be flim flam.

BadWolf1701

How do you begin to narrow down all of the variables? Such as chemicals in the food chain today, process food, ease of access to sugars and fats as well as a mostly sedentary lifestyle vs nomadic or more physical life in the past.

Kelsey Larson

Why do so many psych meds impact weight? Does it change people’s metabolism, or is there something else going on?

Erin Gunderson

How much of the "biohacking" hype is based on sound science? How does fasting *really* affect metabolism in humans?

Alex Morales

I study cellular metabolism in the context of human brain development, I’m curious how much of your work looks at the effect of parental metabolism on gestation and if there are key differences among species or even across human evolution.

Anna

Is metabolism something that is changeable in an animal? Or are you stuck with what you got?

Kate E

- Is it true that maintaining a calorie deficit is the best way to lose weight? - The benefits of low fat/non-fat products were touted for a while, but that guidance seems to be changing. (See recent NY Times article "Are Low-Fat Dairy Products Really Healthier?") Does our expert have an opinion about low fat/no fat products and their impact on health and weight?

Aurelia Ven

How much does the mental state and psychology influence metabolism? Thinking more in terms of brain chemistry, hormones, etc.

Shelby Reardon

Do spicy foods or any specific foods help increase metabolism?

Ange Percy

I'm desperate to know why some people are always warm and some (me) are always cold? I am healthy and active but this doesn't seem to make a difference.

Susan Baker

**1st time question asker** Do female chimpanzees and apes experience menopause similarly to humans and does it affect their metabolism, as compared to older males?

RJ Doidge

Is there validity to some people simply having a fast metabolism? Is there a way to alter this?

Jasja dekker

How do occuring species affect digestion, metabolism and vice versa? How adaptive are humans? Thinking the high prevalence of lacto-intolerance in some countries versus using a lot of dairy here in western Europe, almost exclusive meat diets in the high north versus low-meat diets many places elsewhere. (I know I had to learn to eat spicier food, but as although my family is Dutch as far as I can look back in the family tree, never learned to eat herring, blegh!).

emmie

is there a connection to metabolism and menstrual cycles? coming from a girl with a super irregular/basically nonexistent cycle who cannot seem to keep weight on for her life. why is my body like this?

Kyla C (KAI-luh, rhymes with Myra or Lyla)

OMG this is so exciting. 1) can you talk about how humans evolved to have the metabolism we do? are there any funky ancestral remnants in our metabolic processes you find interesting?

Shelby Reardon

When is the best time to eat in the morning (relative to waking up) to kick-start my metabolism? Or has my whole life been a lie and breakfast doesn't kick-start metabolisms?

Sivvy

In that save vein: I have one dog that has an incredible metabolism, but another (same size, different breed, but both sporting dogs) that has a sllloooooooowwww metabolism. Why?

Elliot McAtarsney

How effective is periodic fasting for your metabolism? Coming from the point of view of a type 1 diabetic who has been recommended it by some doctors and told absolutely not by others. Would love to hear your thoughts!

Kieran C.

What’s the newest science behind weight and health? I’m seeing some articles come out saying that people carrying “a little extra” tend to survive illness better (especially in old age) - is there any support behind the long-held paradigm that “thinnest” is best?

Linda Walz

An observation, all of my family born after 1945 has struggled with weight issues. Their parents and grandparents are fairly thin. I have to wonder!

StrawbrryMom 🍓

What is the purpose of metabolism outside of weight management?

Alana Okuley

This may be gross…but I am so curious and wondering if there is any connection between metabolism and bowl movements? Also, what is the metabolism for our pets like? Is this important for pets too?

Ang

Can you talk about the relationship between metabolism and hunger? And how it may differ between individuals? (Aka why do I get hungry & cranky if I don’t eat lunch and my partner can go all day without eating and feel fine?)

Olga Kolesnikova

When I was younger I had an overactive thyroid and until I got treatment I was always starving, I would eat so much food and was still so thin. I didn't do more exercise or anything. What actually happened to all the calories I was eating?

Kyla C (KAI-luh, rhymes with Myra or Lyla)

2) can you talk about how we are susceptible to certain diseases based on our human metabolism vs other animals? like, why do we have so much type 2 diabetes?

Kelsy Simpson

How does metabolism change during the life cycle of mammals? Does it differe depending on species?

Hope J 🏳️‍🌈

Yes, I tend to feel overheated walking even in the winter but other people I know wear multiple layers because they are so cold.

Chris Curious

Do people with faster metabolisms create more heat?

Jennifer R.

1) What are the biggest misconceptions people have about metabolism? What drives you absolutely bonkers to hear in science or the media? 2) With our society being rampantly fatphobic and always up for the latest health fad, what role does unconscious bias play in the scientific community / studies of metabolism and how do scientists try to eliminate bias or preconceived ideas?

Will Clark

What is metabolism? Hormone, measurement, enzyme...?

Jen A.

Menopause and metabolism changes. Whhhyyyyyyy. 😭😭😭😭

Shelby Smith

Are endocrine disorders like PCOS and thyroid disease a relatively modern and/or human phenomenon? Or has there been evidence that they have always existed?

mish the fish

would you say that across humans, there are many variations in how their metabolism works (fast vs slow, etc)?

Lisa P

Seconding those asking about hormones and metabolism, particularly perimenopause and menopause. Can diet changes help maintain muscle and bone mass during this hormonal transition?

Laurel Sindewald

True or ultra-runner flim flam: running long distances causes your digestive system to shut down if you don't intake enough solid food. Asking as a nervous future 100 mile race runner.

Devin McPeek

How much innate genetic and/or epigenetic programming is involved in metabolism? Do we know about any of the mechanisms that may cause one person to retain more fat than others? And how do those mechanisms affect other systems in the body?

Hope J 🏳️‍🌈

What foods contribute to better metabolism? Which foods should one avoid? Or do food or other factors not affect metabolism at all and it’s more genetic?

Monica Olvera

I probably have the same questions as a a lot of people. Wtaf is the metabolism? How do hormones affect the metabolic systems in the body? Is there really a metabolic “set-point?” Does the metabolism rev up or slow down depending on caloric intake over time? All these hacks and tricks to speed up the metabolism, like intermittent fasting or doing HIIT workouts, do they actually have a an effect on the metabolism that is significant for health? What do scientists think of the argument that the body positivity movement is promoting “unhealthy behaviors?”

Leanna Shuster

Is it true that metabolic rate tends to slow as we age? If so, is there some sort of evolutionary explanation as to why this might actually be beneficial?!

Diana Moreno

Is metabolism something every human develops differently ? Is it hereditary?

Julie Scott

I guess that I am curious about the relationship between metabolism and people's weight. You know how people might say that they have a high or low metabolism. Is that true and is there anything to claims that products can change a person's metabolism?

Emma Henson

Is it possible to affect your natural metabolism or is everything saying you B.S.?

Emma Sherwood

Can you ask about how metabolism and energy intersect with sleep? Specifically we know that some people have different sleep needs than others, but how is this linked to metabolism? When people don't meet their individual sleep needs, what are the impacts of this on metabolism and energy?

Vanessa Frey

Could you talk about what has truth to it and what is flim flam regarding CICO(calories in/calories out), HAES (healthy at every size), and if intermittant fasting is or isn't healthy/will do anything for weight management? My parents swear by fasting as a way to control their metabolism, but I suspect it just works because they aren't consuming as many calories.

Chandler Witherington

I've heard that if you screw up your metabolism (i.e. from an eating disorder or rapid weight loss or something) it takes 10 years for it to re-regulate. Is there any truth to that?

Pavka34

To what degree is metabolism hereditary? Does environment impact metabolism, particularly when you are young?

Laurel Sindewald

Does becoming fat-adapted lead to easier loss of visceral fat and more sustained energy? I'm thinking of Laird Hamilton's high-fat diet and the whole keto thing.

Larn Arn

So many questions about hormones and metabolism! Just want to emphasize questions regarding menopause and perimenopause. What is the relationship between estrogen and metabolism? Why do some people seem to be more or less impacted by shifting hormones as it relates to their metabolism?

Leanna Shuster

When you're discussing diets, please talk about the scientific logic or lack thereof around intermittent fasting!

Anuja Joshi

What is the relationship between thyroid hormones and metabolism?

Lizzy Martinez

How do medications like hormonal birth control impact metabolism? And what happens to metabolism when stopping such medications?

Kelsy Simpson

Oooh! I also support this question!

Dave Cannon

I'll think of the perfect question while listening to the episode...

Eating dog hair for a living

I've been on thyroid meds since my mid 30's, I'm 55 now. I have hypothyroidism what is generally the best meds, what the Dr.s prescribe like levothroxine, Np thyroid or the animal supplement thyroid you can get from vitamin companies? How can I feel less tired? How often should you get your levels checked? And should I be seeing an adrenal specialist or stay with my family Dr.?

Wayne Halliburton

I see a lot of people asking about hormones! As a trans guy, what (if anything) is happening to my metabolism as I take testosterone?

Kayfons

Do the metabolisms of two genetically identical people (eg twins) who eat the same thing have different responses? And if so, is it a gut microbiome thing or is it more complex?

Scarlet P

Is metabolism influenced by menstrual cycle (and associated hormones)? Do people menstruate experience varying metabolic levels at different parts of their cycle? (and is it very different from how metabolism may fluxuate for those who don't?)

Larn Arn

Also - there seems to be so much conflicting info on metabolism. Common understanding seems to be, as we age our metabolism slows. I remember seeing something in the NYT in the last year or so covering studies that debunked that and that our metabolism generally stays the same until we’re much older — that it’s other factors that contribute to weight gain with aging as some experience. Can you clarify what the current research saying about aging and metabolism?

Ry_ofthetiger

A few years ago, I had a chemically aided “aha” moment when I “realized” that we need oxygen because oxygen is flammable and our bodies need it to burn calories. How off base am I with that armchair discovery?

Alexandre Catulle

Why does it have to be so complicated? What is the best way to manage your diet?

Jules Clement

Is it true that regardless of how much one eats or how much one moves (calories-in/calories-out) that the metabolism of humans burns the same amount of total calories? I heard a reference of a study that demonstrated this, but have not yet researched it.

Rachel von Morrigan

How does stress affect metabolism? I’m mid divorce (whomp-wah) and have lost way too much weight too fast, but I haven’t changed my eating habits. What the farts is happening?

Margie and Dexter

How does metabolism change as you age? How does this differ for women and men? To what extent can you reset your metabolism with exercise?

Kathleen Regovich

How much is metabolism affected by genetics and how much is it affected by diet and exercise? Does losing fat and gaining muscle really change your metabolism?

Paul Hoffman

What is your view of "overweight" and life expectancy and quality of life? If someone is 50 and maybe 40 pounds heavier than average for their height and probably not going to lose it, what should they expect other than public shaming?

Joe Porfido

Is it possible to create calorie neutral foods? I need something to monch on

Allison Muller

Wow. I have 3 tabs open about metabolism research just from this week…perfect timing!!

Allie Brown

How can alcohol have calories if it isn’t made of the usual macronutrients? How is it converted to energy?

Ryan Walsh

What is the real science behind how the metabolism as we age? Is it true there are a few metabolic cliffs or is it more of a general decline over time? Or is this all flim flam and our metabolism is generally stable.

ReigningEmily

So my mom will get these infrequent and overwhelming insatiable craving for sour things. Lemons, pickles, green apples. It comes every few months and lasts a few weeks. Her doctor doesn’t know why but I figure that there has to be some sort of reason. Thoughts?

Nicole D-G

I was going to ask the same thing! I just heard that humans always burn 2500 calories on average no matter if they’re present day office workers or hunter-gatherers. Is that true?

Katie Murray

Along these lines, my mom always told me growing up thin that my metabolism would eventually “catch up with me.” She’d say not-so-helpful things like, “I used to be a twig like you. Just wait!” I wondered if her experience was age related or more connected to her having kids. Any thoughts?

Allie Brown

What contributes to one’s Base Metabolic Rate (BMR)? Is it just the energy required for all our cells to perform their usual maintenance?

Keegan Newman

Does testosterone affect metabolism? After I started transitioning and began taking testosterone I lost roughly 80lbs. So I was wondering if there’s a hormone component to it or not. Thanks!

Jadine Lannon

This! Is there an actual casual relationship between metabolism and weight for each individual?

Euan Munro

Why does my breath absolutely reek when I've been fasting?

Melanie Lee

How do you measure metabolism? Can you get your metabolism checked? And what kind of things influence this bad boi?

Allison Muller

Does metabolism change the half life/quarter life of substances like caffeine or prescription drugs? Our bodies all operate and process differently and when I have looked at some studies on the subject, metabolism isn’t mentioned at all…?

FlowerHittelman

What is the relationship between getting enough good sleep and metabolism? ie If I don't sleep enough, will it make my ass look big?

Paul Shakhovskoy

Does exercise actually increase your metabolism? For how long? And is it different for different exercises (cardio vs weights etc)

Allison Muller

For example: the relief from something like Ibuprofen may not last as long for those with higher metabolisms…

Brittney Corrigan

Why is it so common to gain weight during menopause, and why is it so difficult to lose it? I never had a problem with weight management until I hit menopause, and now the struggle is real!

Cece Tincknell

Do we really have any power to change how efficiently we metabolize our food? What other physiological systems play a role in metabolism? How does the mechanism of absorption change how we metabolize things like drugs and chemicals (i.e. oral, rectal, dermal, nasal, etc…)

Dana

Why doesn’t mine work!?

Gretchen Schroeder

Same here! Always slim/athletic build until menopause then suddenly stubborn weight gain!

Hezy Anholt

How well do you feel this analogy tracks?? I like to think of the variation in body shape n' heft among different peeps (within healthy normal parameters s) as being like the variation among dog breeds. I for example am a Labrador. I have friends with similar exercise and eating habits to myself who are Italian greyhounds. Some people are pitties or st Bernards. Don't starve your st Bernard in a vain attempt to make her look like a greyhound. iss not healthy.

Ferf Brownoff

Is it true you can "train" or impact your metabolic rate through restrictive eating? My dietician told me that restrictive eating slows one's metabolism, but eating enough food actually speeds it up.. if this is the case, what are the limitations of how much we eat impacting metabolism, even if metabolism changes from person to person?

Hezy Anholt

Great apes in captivity struggle with cardiovascular disease. What are some of the similarities and differences between humans and great apes in terms of the kinds of cardiovascular diseases we typically see?

Matt Ceccato

How much is metabolism determined by genetics?

Felix Lasselle

If someone struggles to gain weight and is always skinny regardless of diet and exercise changes, is their body just super efficient at burning calories in exactly the right way? Or is it the body not absorbing nutrients properly? Asking for a friend.

Chelsea

How do drinking zero calorie but flavored sodas actually affect metabolism? Is it just the sugary taste making us eat more? Or do the chemical sweeteners affect our system more than that?

Rabia Sadiq

I swear my metabolism is broken! I need to know how recharge or reset it so I actually lose body fat! Please help me!

Mo

Potentially a really stupid question but is metabolism related to heart rate/life expectancy? I'm thinking of small mammals like rodents who have fast heartbeats and short lifes but also super high metabolism compared to humans. And does this mean that a fast metabolism is related to how fast you can heal as well? Again thinking of rodents, or specifically rats where wounds from a surgery/injury can close up crazy fast (again, compared to humans). Is it because their metabolism are so fast?

Carlos Alvarez

The new GLP-1, GIP, and glucagon agonist peptides appear to be modifying metabolism. Can you cover that and how it may affect people now and long term? In particular, retatrutide seems to give users monster energy like an upper, while increasing TDEE.

Mimz

Why do some people have fast a metabolism and others slow?

Catherine BH

Oooh yes!!! I'm definitely going to cite this episode when I teach a metabolism section next semester!! I'm a first time question asker: I know understanding the gut microbiome and its importance for metabolism is still relatively new and we're still learning, but do we know anything about the co-evolution of our diets and microbiomes?

Joe A

What would happen if I were to consume 50,000 extra calories in a day? Could my body metabolize all of it? Would there be a difference if those 50,000 extra calories were spread out over a week? Asking for a friend.

Katherine Fox

What role does the gut microbiome play in metabolism?

Megan Bolton

Similar to the questions about hormones. What effect does PCOS have on metabolism?

Dr. Wiggles

First time Q asker :-) Fact or flim flam: Creatures with higher metabolisms generally live shorter lives ... do they experience time slower? Times is all relative right?

Hannah Gorrie

Are there specific systems/organs/glands that regulate metabolism, and if one of them is wonky it throws the metabolism off? Or are metabolic disorders seated in the same foundational issue with one part of the body?

Hannah Boyd

What's their favorite hormone? :)

Hannah Boyd

Why does metabolism slow down as we age? Is it because we should probably just be dead already?

Paulina Krasińska-Sroka

Why do we process some substances into energy and others into fat? Is it based purely on the excess caloric intake like diets often tell us? I'm also wondering specifically about my condition - insulin resistance - where my body produces insulin but doesn't use it properly and as a result any carbohydrates accumulate as fat, especially around waist (it's so characteristic shape that one gets that I was directed to a specialist purely on how I looked and the GD was spot on!). Why does it happen? And why so specific outcome in looks?

Matthew Winn

When you do something to change your metabolism, how long does that change last?

Lee Wang

I'm naturally thin, but I also get cold very easily (particularly in my hands and feet). Is that metabolism-related or something else (I guess the ratio of surface area to body mass)?

Amanda Washington

How does fasting affect metabolism, or daily “fasting” (ie the idea of fasting between 7pm and 11am)? Is it true that you gain weight if you eat within a couple hours of bedtime?

Rachel Titsworth

First time question asker: Is my naturally slender husband correct that metabolism has nothing to do with the fact that he can eat whatever he wants and not gain fat, while I have always struggled with my weight? It's infuriating!

Kara

Please talk about tardigrades!

Michael Wegman

Is it even possible to "boost" your metabolism or do anything to change the speed at which you metabolize food to a degree that will make any noticeable difference in your daily life?

BeckytheSassySeagrassScientist

What actually happens to 'fat' when you 'lose it'? I always think of the little Adipose creatures popping out in Dr Who.

slam whitey

Why can’t I drink caffeine without getting mad anxiety?

Amandaloveskurt

Is it true that some people just have a “slower” or “faster” metabolism than others and what might the purpose of that be from an evolutionary standpoint?

BeckytheSassySeagrassScientist

Is a slower or a faster metabolism better for survival? We slow metabolism people would last longer in the jungle with less access to food right? Does this vary by species/circumstance?

Angie Smith

*first time Do supplements claiming to boost metabolism actually work? Also, what foods are good for this?

Brittany Kaufman

Are there any studies on SSRIs and their effect on metabolism? There are a lot of anecdotes about weight gain/loss after starting these meds but a lot of docs insist there's no link. Wondering why that is.

Steven Hansen

I could easily consume 3-4,000 calories a day in my late teens and early twenties. I did eat healthy (no fast food). At the time I was 6'4" weighed 154 lb and lived a very relaxed lifestyle (no gym). Why am I such an inefficient Human?

Chandler Witherington

Same I had one in high school and into college. How long am I screwed?????

Margot Louis

Is it true some people have a naturally fast metabolism and can eat more without gaining weight?

Margot Louis

Try ginger to increase circulation! Always helps with my cold hands/feet in the winter

ScienceInTheArt

Is it even possible to change one's base metabolism?

Nicky G

First time question asker! Is metabolism of food and energy correlated with how the same body metabolises medications? Thank you!

norma Vazquez

First time question asker here!!! How much do hormones affect your metabolism? For women with thyroid disorders or PCOS, is it best to regulate diet/exercise or hormones or both in order to stabilize their metabolism? Also, does fasting for more than 2-3 days have a significant impact on the metabolism?

Lina Staudt

What is a metabolism? How does it change, what affects it (age, calories, random lemon water)? How can we work with it? Can you change your metabolism (e.g 'boost it' by eating certain stuff or slowing it down by eating to little calories)?

Howard Bergman

Great question! Without those microbes, we wouldn’t be digesting anything!

Lina Staudt

As someone who never gets enough sleep - sadly, VERY sadly no I dont think its that easy ._.

Linda Bailey

First time asker. Is there a direct correlation between depressed metabolism and PTSD and/or prolonged intense stress? Love your pod!

ZZ

First time asker with a long-time questions that Google can't answer! Is there a limit to how many calories a body can process in a limited span of time? Like if I managed to eat 6 pizzas in an hour, what happens to the excess? Surely it can't all be absorbed?

Witch of the Widdle Wiggly Guys

First time question asker and it's a personal one on metabolism and cholesterol: I have hashimoto's/hypothyroidism (managed with meds) and I've had high cholesterol for a few years now. When I first found out I was surprised because I was very active and a vegetarian with no blood pressure issues. Since then I've lost 25 pounds, gone almost completely vegan and eat almost no fried foods, and am still very active but my cholesterol hasn't budged even though I've been "doing everything right". I'm pretty tired of doctors talking down to me for not trying hard enough/recommending I do things that I'm already doing and I'm wondering why might my metabolism not be able to get it together here? Is there something else I should be trying?

Jessie

(FTQA) Honestly, what is the deal with probiotics? (I know they affect more than metabolism but like…) I was taking them last year and got some serious stomach pains. When I googled it there were a ton of related FAQs, but no research to answer! I’ve tepidly started taking them again this year and so far no pain and I have no idea why!!

Jessie

THIS! Literally everyone I know is always warmer than me.

Average_pi

How does metabolism change from childhood to adulthood/ for people of different genders?

Ruby Booth

What can he tell us about the idea of the body's set point? Why does our metabolism have a desired weight for us and how does it pick when to speed up or slow down?

Ma's Nature Walks

How does pregnancy and the post-partum process effect metabolism?

Ma's Nature Walks

Also, how do things like intestinal resection influence metabolism?

Aileen Lands

Yes! Polycystic ovaries here, I exercise a LOT and eat healthy but really feel like the deck is stacked against me (was recently diagnosed with super high cholesterol, my doc said “eat healthy and exercise”, which I already do). Why are female hormones so whack?

Jenna Congdon

I hope the ologist elaborates on this!! But as far as my understanding goes (nurse with a health-coaching background), the answer is yes, at least a little bit! #1 way to boost it is by building muscle tissue. That said, I definitely don't know all there is to know about this, so I second this question!!

Anna Reed

What is the relationship between sweat and metabolism (asked by a very naturally sweaty person)?

Jenna Congdon

I would love if you discussed the effects of chronic dieting on metabolism. Is "reverse dieting" a real thing? (eating a bunch MORE to "kickstart your metabolism" after years of undereating). There is often talk of different metabolic "types"- endomorphic vs exomorphic being a common one. I believe that's pretty outdated, but it really does seem like different people respond to different amounts/types of food differently. Example: my tall, thin husband who can eat the whole refrigerator and still be thin, vs other people who are just built to be thicc no matter what they do. Do animals have this same thing? Are there naturally curvy chimps out there with chimp friends who are naturally string beans? Do they talk about how they wish they could swap clothes but it would never work?

Magdalena Castillo

Can the benefits of diet and exercise be inherited? My boyfriend read a paper about mice that said that some benefits of exercised may be passed on to the offspring

Rebecca Cloud

For someone who has been told they have low metabolism, how does that change while aging? Does it stay the same or get even worse?

Anjali Himali

Why does our metabolism change over time?

Lisa Rowell

Can you address the impact of pre-menopause, peri-menopause, and menopause itself on metabolism? And then give us the magic bullet on how to circumvent the slowing down of metabolism? I am also extremely curious about how type 2 diabetes and metabolism intersect. Thanks!

Lau

What happens to our metabolism during menopause? Why do so many women gain weight without any lifestyle changes and why is most of that weight in the boobs and around the waist?

Jason Lowenthal

I regularly yell at my FitBit after a grueling workout when it says I've only burned 400 or so calories. How accurate IS my FitBit? Wondering about the accuracy of sleep data too, but that's a past episode...

Lindsay Mixer

What makes our metabolism different when it comes to breaking down food versus meds? My metabolism with food is average, but I break down meds and alcohol so quickly I have to take a much higher dose than most people to get the same effects. I’m currently post-op and having to take twice the usual dosage of pain meds twice as often because otherwise I get no relief. What makes that happen and is there any way to change it?

norma Vazquez

Yes, this is me too! Also, I noticed a change with weight gain and slower metabolism when I came off of BC after being on it for 10 years!

Sophia A

Do the supplements that claim to boost your metabolism work? And if so, what are they boosting? Metabolism is all chemical reactions in the body, how can these supplements possibly speed up ALL chemical reactions? Would that even be beneficial?

Shai Clai

Hi! What impact are our modern habits (access to quick, high calorie) having on how our metabolism functions?

Colby Evans

Love the question - it's easy to see the relationship between calories and moving a big old body around the world... but how much vampire drain from the accessories, like thinking?

RoadLesTravelled

Any advice on adapting to changes in metabolism as we age?

Colby Evans

similar question - after eating, maybe calorie dense foods, will the body temp change? Feels like my metabolism goes into overdrive a bit to churn through everything I chewed through

winn

what happens to our metabolism during sleep? is that why my body temp goes up so much? i’ve been told that when I sleep I’m as effective as a radiator.

Earl of Greymalkin

1) How does the composition of your microbiota affect metabolism? 2) How much is metabolism nature vs nurture? 3) What happens when you have a drastic, sudden change in lifestyle, like diet composition or activity level (thinking about when I'm traveling and on airplanes for way too long and eating very different things)? How do all the systems balance themselves and if they take too long to do so, does it make us feel crappy? (Or is that more the time zone change?) 4) How does circadian rhythm dictate metabolic processes? What happens when we are awake versus asleep? 5) Any advice for what kinds of food to eat for sustained energy levels over time? Is a sugar rush and crash real? 6) Are processed foods messing us up? 7) Are non-human primates or other animals (like our companion animals) doing anything substantially different than humans or is it all basically the same systems? 8) How much should we love the mitochondria, the powerhouse of the cell?

Marianne Thomas

Why am I so cold? Do any of the other great apes have to deal with such bullshit? How come we're the only ones who can't manage basic thermoregulation?

Jacob Elsbree

How is metabolism liked to circadian rhythms? I’m assuming it slows during sleep, but during the waking hours is it idling at a constant rate or is it fluctuating all over the place?

Mrs Mills

Thats an awesome analogy. In the same vein, we shouldn't feed a chihuahua expecting it to transform into Great Dane.

Hezy Anholt

It seems like diet and exercise recommendations are constantly changing. How much of this do you think is due to p-hacking?

Lindsay Mixer

Omg me too!! Honestly they’re so cute sometimes I get myself to eat by thinking “I gotta feed my adipose”

Hezy Anholt

To what extent has the diet industry influenced what BMI cutoffs are categorized as overweight and obese in the US?

Griffin Russell

People hate me cause I can eat enormous amounts of terribly unhealthy food and not gain any weight.. is this due to my having a high metabolism? Someone told me that once and I’ve always wondered

omg im so excited for this episode!!!!! THANK YOU ALIE im so pumped this is exactly what i was hoping for hahaha <3 question-wise, I have recently been reading a lot about the positive impact different teas can have on the body. a big one that people seem to throw around is that many different types of teas are great for metabolism and weight loss (like pu'erh and green tea)... is this true or is it really just because drinking water is good for your body (lol). Love ya alie

Michael Swords

How are processed foods affecting our metabolism, generally? It'd be great if food deserts could be mentioned in connection too!

SmoothKriminal

I have Hashimotos and MTFHR (my mitochondria don't know how to powerhouse, apparently), and doctors have told me my metabolism is slow, but haven't really explained how these things link up. Can you talk about how the endocrine system and metabolism interact, and what effects this might have on how we process foods?

Hezy Anholt

So I'm not an MD (hard disclaimer) but I am somewhat suspicious of cholesterols as biomarkers for risk of cardiovascular disease. I'm sure it also depends on what type of cholesterol your are talking about and HOW high your values are. But see Hypothyroidism, lipids, and lipidomics Review Open access 17 June 2023

Erin Burbidge

Are there any epigenetic influences on metabolism? Things that we might have inherited from our parents, or might pass on to our children?

Meg W

I have heard workout gurus claim that doing "interval sprints" once a week will activate metabolism. Is this true or film flam? Example: 30 second balls to the wall sprint of anything, 60 second rest Repeat for 10ish minutes.

Erin Burbidge

There was a study in 2016 that showed that contestants from that *TERRIBLE SHOW* The Biggest Loser had long-lasting reductions in their metabolism following the crash dieting and dramatic weight loss they experienced. Have other studies found the same thing resulting in people experiencing dramatic changes in eating and exercise habits?

Cate Muenker

Uggh, why does my body prefer to store fat like an Irish peasant during the potato famine!?! (Full disclosure, I am addicted to fries, but the amount I eat does not correspond to my weight gain, I also have hypothyroidism, but am medicated with clinically normal T4 & TSH, but does everyone have a unique “normal range”). Is there really a magic ratio of fasting and eating depending on your body shape? Do monkeys have these problems or can we blame processed foods?

Nathan Howard

How important is gut microbiome to metabolism? I'm visiting India soon and apparently my lack of a "local" microbiome can cause digestion issues, could that also affect my energy levels?

Emily Staw-fur

Where in my body is my metabolism? Is it in every organ associated with digestion? Or is there a specific organ that controls the metabolism?

Emily Staw-fur

Can frequency of eating actually influence your metabolism? I've heard everything from eating frequent small meals to a single large meal (intermittent fasting) is the key to a fast metabolism

Emily Staw-fur

How much of our metabolism is made up of controllable factors (diet, exercise, etc) versus uncontrollable factors (genetics)?

PopsicleEmperor

How does trauma and anxiety impact our metabolism?

Tristin Berg

HOW do I gain weight with a super high metabolism? My family loses weight too easily and has trouble gaining it back. How big of a factor does gut biome have in metabolic rate?

Grayson

How does neurodivergence affect metabolism?

Alyssa Simmons

I keep seeing adds for "somatic workouts" on my social media to "kickstart my metabolism". Is that flimflam? Is there any basis for the claims being made to me via algorithm sabotage?

Rachel Prestayko

Same question! Family members on my father's side usually have an incredibly fast metabolism until around age 30. Is there also a genetic component to how it changes as we age?

Karen Tam

By gradually eating less at each meal (to lose weight) does our metabolism stay the same, increase, or decrease?

Voxothoth

How does caffeine affect metabolism, both short and long term? Sometimes if I drink coffee with breakfast, I get super hungry pretty frequently after. Though I feel like maybe that's more blood sugar related...

Elizabeth A Halliday-Reynolds

What's a lady to do when she finds her middle expanding after 50. I have heard that once our wee ovaries go to rest, we somehow convert estrogen from out belly fat. Please give us some tips to support this process naturally but with out the spare tires.

Dionne Needham

How does age, stages of life, perimenopause, menopause effect our metabolism? What about monthly hormones for women around their periods. I get super hungry at certain times of the month. Do men get the same thing with hormones fluctuating.

Bonnie M Rutherford

How does the health of our gut microbiome affect our metabolism?

Sasha

What future technology are excited about in terms of being able to understand metabolism both at home and in medical practices?

Julie Glass

Caffeine…why does just a bit keep me awake for days but my husband can drink a pot before bed?

Joyclyn Vincent

Oh Alie, I’m scared to participate in this one… will this episode be safe for those of us who are recovering from eating disorders or should we maybe give this one a miss? I love the show but am concerned this one might not be a safe space for everyone.

Tari Lee Johnson

Several questions. There are supplements being sold that nourish/feed your mitochondria. I am assuming this is bunk. I do wish I'd invented it $$$. Second question, I've seen ads for supplements that speed up the Kreb's cycle to burn more calories/have more energy. What?

Nicole Harper

i saw someone else suggest this and I would LOVE to know!! Can this explain why I am SO cold all the time but my boyfriend wears shorts in 20 degree weather

Nicole Harper

Also is there anything I can change in my diet or habits to be warmer ?!?

Greg Roth

Please explain how to perform Reverse Dieting, it makes no sense to me!

Megan Ramirez

I've heard that drinking green tea can help boost your metabolism. Is this true or flim flam? If true, how does it work?

Molly Rupp

I'm having the same worry! esp reading through some of the questions here

Felix

what's the deal with myalgic encephalomyelitis? is it a problem with someone's metabolism? are we anywhere near finding treatments for it?

Susan Singley

What effect does trauma have on our health and metabolism?

Susan Singley

What is the relationship between BMI and metabolism? Does BMI affect the metabolism or does metabolism affect BMI?

Dawn and Eric Easton

I'm in my latish 60's. How can I encourage my glacial metabolism to kick itself up a notch or 20? I run, do yoga, etc., but my once hummingbird like metabolism has decided to just flat out stop.

Sharon

Do metabolic enhancers with things like ashwagandha and teacrine work? Does B12 boost energy/metabolism?

Nicole Austin

What’s the latest on the relationship between the gut microbiome and metabolism? For a while there were lots of articles and it seemed like fecal transplants were being proposed as a cure for just about everything, but it hasn’t materialized. Is that just because pharmaceutical marketing agencies haven’t yet figured out a catchy slogan to overcome the ick factor? Or do we know now that it doesn’t really work like that?

Mckaylia Marshall

Is it true that certain foods like pasta can lose calorie content when it sits overnight in a fridge? Additionally, is it true that the amount of calories we absorb correlates to the length of our small intestine?

Mrs Mills

FTQA - Asking for a friend (no, really) - my friend received a message from her 8 year old daughter's school asking that Mum add more food to daughter's lunch box as daughter had hoovered the hotdog, yoghurt, apple and sweet treat at morning tea. My friend called the school and the office manager said that AT THIS TIME OF YEAR (Southern hemisphere, so late spring/early summer) they often have extra food on hand as they've found that children go through a growth spurt. Is there any anthropological evidence for this anecdote? Does the human metabolism change with the seasons? Have I finally found a justification for stuffing myself with chips and chocolate as soon as the weather hints at being colder? BTW - Love you Pod Dad! <3

Design 83

Does it really take less energy for humans to digest meats rather than vegetables (ignoring all the extra calories used for chewing/biting) ?

Design 83

Can you explain why it isn’t turkey that makes people drowsy - isn’t it just the larger-than-normal amount we Americans tend to eat on Thanksgiving?

Design 83

How useful are multi-vitamins for the average adult? If I miss a few days am I teally throwimg my ‘system’ out of whack?

Corey

FTQA - Can you talk about set point/ range theory and the Minnesota Starvation Experiment (specifically how the men started as 'healthy, fit, and of sound mind', and the semi starvation (1500 calories- sit on that for a bit) caused them to develop food anxieties/ precocious behaviour, and one guy even chopped of his thumb---- but in the Recovery Phase, the men needed 5-6000 and even upto 11,000 to reach satiety and continue weight restoration, and after 6-18 months they returned to "normal"* (*whatever that is 🤷😅) I think this case study/ experiment really highlights the flexibility and unpredictable nature of metabolism, and always blew my mind as someone recovered from Anorexia.

Corey

Ooohh- resistant starches!! this is because the starches realign and become resistant to digestion, which we *think* reduces the availability of carbs in the rice, potato, or pasta by about 30%

Quincy J Byrne

How much variation is there in metabolism from person to person? How are those differences quantified?

Corey

This always drive me wild- and it's based on the idea of slow adjustments, but honestly - your body is so capable and will even out the 8-10 week process just quickly as you find your knew maintenance. It's extending the restriction and hunger for the short term "potentially" staying "slightly" leaner- but honestly, you deserve to eat like an adult (enough to adequately fuel the life you live) and the difference is 1-2% bf (maybe) - i.e. nothing. (Your friendly pt)

Corey

I've had a long suspicion that many people subtly under eat- not enough to affect their weight because our brains are pretty good at that, but enough to affect energy/ body temp (one of the ways your body protects you from starving is reducing your temp so you need less energy) try food 🤷

Valerie Bertha

Why does my metabolism slow up the older I become even though I continue to exercise?

Valerie Bertha

How much do your genetics affect your metabolism? My husband says his genes make it harder for him to lose weight.

Valerie Bertha

Should we eat less carbs as we become older?

Bender

Is there a way to ramp up the efficiency or quantity of mitochondria within our cells? Or are we stuck with what we inherited from our mamas (and papas)?

Matt Rippon

Ooooh questions about recovery of the metabolism are super interesting- they'll certainly talk about The Biggest Loser (always cited when people talk about recovery of metabolism) and how that show distroyed the contestants metabolism.. I'm sure they'll have lots of questions about how to repair metabolism, but that's really interesting in my opinion. Building muscle tends to be the best advice because it increases your need for calories to feed those muscles, just as it would have for fat... how quickly can you change your BRM (basal metabolic rate) up and down? What are other tactics (other than muscle building) that work on lowering BMR once it's been raised? How does stress and anxiety raise BMR? Does insulin affect BMR in any way? From my lovely wife Jaclyn who bought me this patreon as a Xmas present last year.

Sarah Cork Henderson

I have struggled with my weight for decades, since my teens. Whenever I eat as much as I like, I gained weight except…..at Club Med for some reason. Ate their delicious chocolate and banana bread with breakfast every morning. Fried grouper with lunch. Delicious dinners with wine and ended every night with the best ice cream. I was active but not terribly as I am a lounger, not an athlete. I ate way more daily on vacation than I generally do. And all four times I was there for a week or more, I returned the same weight as when I left for vacation. So, what is going on and could chronic stress from ordinary living in our society be partially to blame for being overweight? Being at Club Med was the most relaxing experience I’ve ever had. And it’s the only time in my life I’ve been able to eat what I wanted and didn’t gain weight.

Kelly Shaver

Why do people always talk about "training [your] metabolism"? Is that as fake as it sounds?

Ms. Nowak

How much of metabolism is genetic and how much is in one's control? (First time asker!)

Anna Elizabeth

can he speak at all on systemic fat phobia and how we treat fat people can have negative effects on their health outcomes? from a friend: she wants to know about intermittent fasting? helpful? flimflam? what’s the deal?

Michael Carron

I’ve never thought of this question before but now I HAVE to know.

Isabelle Newman

Are our brains and metabolism connected? I know that the HPA axis and stress can lead to differences in metabolism but I would love to know more about ways we can care for our brains and the chemical connections between that and metabolism

Mia Batol

Please explain the newest weight loss medicines, Wegovy versus Zep bound and why they work so well and what do we expect for people who are on this moving forward once they have attained their goal weight.

Matt Hirschl

Thoughts on people taking the diabetic shots that suppress appetite that do not have diabetes?

AussieColin

I'm in my 60s and I've struggled all my life with severe weight problems. I'm told that my metabolism, which makes it easy to put on and hard to lose, is "inherited" from my grandparents being short of food when they were growing up during and before the first world war. Is this something that has real evidence behind it?

Zuza

FTQA: do apes or chimpanzees worry about their weight? When we (humans) started to worry about it?

floraandthefaun

same here! i'm anxiously hoping that you will be as gentle and considerate in this episode - regarding people affected by eating disorders and/or fat phobia - as we know you to be from other episodes/topics, alie <3

Erik K

How does metabolism effect you feeling hungry after eating a meal?

Erik K

How do you figure out the best time and amount to eat to balance with your metabolism and energy levels

Sarah Morcom

From my partner Tom: does a "faster" metabolism mean healthier? (Or is your body compromising on energy stores or something else which makes it less advantageous)

Sia

There are new medications to combat obesity - do they have an effect on metabolism?

Lanice J

Are there any studies linking population genetics to obesity ? Ie African background and increased risk of hypertension diabetes and obesity? Asian and increased risk of lower weight gain and diabetes? What is the presumed benefit?

Lanice J

What are the studies on epigenetics and obesity ie maternal starvation and her offspring with obesity

Milinda B

This may be the wrong ologist for this question, but I’ll give it a go. What’s the deal with IBS? Is it really just a bullshit diagnosis for when doctors don’t know what else to say, as the woman at that street market told me? Is it really “just” stress? And why does stress eff up my stomach so badly?

Calla Turnbull

Is metabolism something you can change or influence through lifestyle decisions? and if yes, is there anything we should be doing (outside of being generally healthy)? I worry that bad nutrition choices as a teenager permanently changed the way my body metabolizes.

Felipe Jimenez

Some of us have to work out hard to actually burn some calories, while others have such a well-running metabolism that they seem to burn the food on the spot, as they eat it. What´s up with this?? Why some of us are cursed :(

Guido

Why large animals usually live for decades, while the small ones tend to have a shorter existance? Do larger individuals live longer on average compared to smaller ones of the same species?

Gavin Roach

Every year in late November I get the urge to hibernate, but sadly it turns out I'm not a bear. Will my dream ever come true (thinking maybe just a little more seriously e.g. for space travel)?

Anne

I’m gluten free, does that affect my metabolism? Why do people think that not eating gluten makes you thinner?

Kendall M

Do medications like antidepressants mess with your metabolism, is that why a common side effect is weight gain?

Dylan V

How much of the data in this field is specific chemical pathways/mechanisms, and how much is based on studies of popluations of people?

Emma Skye

** In the fitness community, it's commonly mentioned that cardio burns more calories during exercise, while strength training boosts metabolism throughout the day. However, nobody ever explains why! Does strength training's ability to boost metabolism primarily rely on long-term muscle-building benefits due to muscle's higher calorie-burning nature, or are there additional shorter-term advantages in comparison to cardio?

Caitlin Morrison

Does human metabolism vary during different times of year at all? Is it slower in the winter months at all??

Chyann Colles

How much does our brain and/or mental health affect our metabolism? And vice versa how much does our metabolism/gut health change our brain and/or mental health??

Angel Estrada

Do people with a high Metabolism-rate produce more NEAT (non-exercise activity thermogenesis) movements? Is it super impactful in life?

GhoulNextDoor

Is it true that there’s such a thing as a “fast” or “slow” metabolism? How fixed is an individuals metabolism rate? And does that impact how quickly drugs take effect and then dissipate?

Jeanette-o-saur

Please debunk all of the ways the term metabolism is used incorrectly in wellness culture

Sam and Katie

How accurate are fitness trackers when it comes to calories taken in through food and calories burned? Is macro tracking the way to go?

Jeanette-o-saur

If this doesn't get covered, I recommend the Maintenance Phase podcast episodes on BMI.

Jeanette-o-saur

Some of us just inherited circulatory systems that are the icy version of dumpster fires. Poop happens

Jeanette-o-saur

Same! I'm always cold during the day and radiate heat like a dragon at night

Jeanette-o-saur

Also I'd appreciate a frank discussion about how anti-fatness plays into our obsession with metabolism

Eridani Mulder

What's the role of epigenetics in determining metabolic rate? Is there a baseline we're stuck with for life?

Rineil Mandre

Jennifer Simon asks: Metabolism changes with age: BS or not?

One Dova

Can you eat anything without getting fat when you exercise regularly?

Hannah Riedl

Content warning: is it true that you burn more calories than you consume while eating an apple?

Hannah Riedl

How do people have slow versus fast metabolisms? Are fast people more fidgety than others or is there something cellular going on?

Matthew Walcher

Do some people actually have faster metabolisms than others? Why would that be?

Matthew Walcher

Is metabolism genetic or something we can change?

Matthew Walcher

People say it's bad to eat late at night, does that have something to do with how it impacts your metabolism?

Rebecca Morrison

FTQA: can you change your metabolism or is it a “you get what you get so don’t throw a fit” kinda thing?

OtterKhaos (KrisP)

I have a few questions! Gonna place all of them below for hopeful-convenience! - What is the relationship between saturated fat and insulin resistance? - It might be too soon to really know, but can a bout of COVID near-permanently change metabolism, provided all other lifestyle factors remain the same as pre-'rona? [Backstory for context: I recently (and finally) caught it and lost 8lbs in a week, then 2 more, and have struggled to gain it back after nearly 3 months of working with a nutritionist. I came across this article and it got me thinking, but I don't speak science well enough! https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8584248/] - I closely follow Dr. William Li's research on metabolism and he's mentioned "metabolism-activating foods" like peppers, pears, kiwis, etc... I'm aware from his book, Eat to Beat Your Diet, that metabolism doesn't change for the majority of your adult life, should epigenetics not be negatively affecting it; with this in mind, if you are of a healthy weight, what could (or would?) these so-called 'metabolism-activating foods' do to your already well-functioning metabolism...? Are they affecting other aspects of your metabolism outside of fat-burning like cholesterol, blood pressure, and blood sugar control... which, in turn, affect fat loss. (NOTE: I'm sure this is in the book too, I just haven't gone back to skim for this insight, figured I'd ask a different expert here!)

How does aging change metabolism? And does being an "active senior" make a difference?

Greg Lewis

Do some foods really speed up metabolism (re the grapefruit diet on the 1960's)?

ZZ

I am super curious to know if it changes with the seasons for adults as well as kids

Denise and Scott Ologiephiles

So many questions as a professor of nutrition! Any empirical evidence on the effect of intermittent fasting on metabolism? And is 6 small meals a day to boost metabolism still debunked? And for my weight loss clients who swear they eat less than 1200 calories a day, a. Is that possible and b. How can they eat more calories without gaining weight? Huge fan, first time poster!

Jude Sullivan

FTQA: I’m a transmasc person about to hit the two year mark on testosterone gender-affirming hormone therapy (GAHT). Both myself (and pretty much anyone on T ever) experiences what feels like an increase in metabolism. Why does this happen? When will it chill out? Please I’m hungry ALL the time and who among us can afford that many groceries in this economy??? Thanks!

Mike Campbell

You might like to read the book “Methuselah’s Zoo” by Steven Austad. Full disclosure: Professor Austad is my cousin, but I don’t get any kick-backs.

Mike Campbell

I’ve heard metabolizing food may be one cause of aging. I still have a fairly fast metabolism even tho’ I just turned 65. I’m fortunate I don’t have to starve myself to stay thin. But does this mean I’ll die soon anyway? I.e., which factor dominates? Calorie restriction? Or avoiding obesity?? I’m a FTQA (but I did reply to one comment before I got to the end of this thread.)

K8 Rouse

I'd love to know more about the link between neurotransmitters in the gut and metabolism. Why and how do SSRIs affect appetite and metabolism? Also, why do I tend to crave junk food when I'm sitting down all day working, and crave healthier foods when I'm able to be active and get outside on a hike?

K8 Rouse

What role does the thyroid play in regulating metabolism and why do thyroid issues seem to be so common, especially for women?

Raja

Are there aspects of metabolism that are established in the first year or two of life? And, if so, should that be factored into the mother's diet at that point if breastfeeding? (Raja pronounced "Rah-ya", like Papaya 😀)

Corinna Regan

I was going to ask if metabolism and weight are really related or if that's a myth :)

Barbara M

Does metabolism affect whether one feels warm or cold much of the time? It seems that heavy people often feel warm when slender people feel cold, but that seems opposite of having fast or slow metabolism.

Alex

Is there a link between metabolism and (psychological) stress? Also, real or flim flam: breakfast is the most important meal of the day because it “jumpstarts the metabolism”

Meagan Walker

Does adding muscle to your body actually boost metabolism in any way that’s meaningful for weight loss?

Meagan Walker

How do our microbiome friends affect our metabolism? I’ve heard that you can do a microbe transplant that causes people to lose weight or become better endurance athletes.

Meagan Walker

Why do I get so hot after eating some foods?

Meagan Walker

Is there *actually* any foods or supplements that affect metabolism or is it all snake oil?

Taniya Heuchert

Huge fan! I’m a type 1 diabetic, can you explain what is happening metabolically when there’s no insulin production? What about Insulin resistance? How does insulin resistance affect metabolism? Stress and when I’m lower in activity are my two personal biggest factors to insulin resistance but I know there are so many others for others. Would LOVE to hear your thoughts.

Heather Leonard

1. Why do some people produce enzymes like lactase or alpha-galactosidase while others don’t? 2. How much does region or culture affect how we metabolize?

calvin f

In human evolution it is speculated that humans broke the "grey ceiling" by developing cooperative breeding what does that sort of changes do we see in metabolism because of this? And why do we see multiple grow stages in humans as opposed to our great ape counter parts?

Audrey Hudak

What can trigger changes in metabolism?

Melissa

I've heard that new evidence has pointed to a virus or viruses affecting your metabolism and leading to obesity. Is there any truth behind this?

Melissa

I think this is just because being heavier is like wearing a built in parka at all times (speaking from experience).

Corey

Often expensive pee if you regularly consume a variety of foods (maybe helpful if on a limited intake- my GP and dietitian independently recommended centrum.)

FTQA - How do you feel about the set-point theory of body weight? What influences our set-point and how long does it take to make a lasting change in either direction?

Melissa Kane

I know you’ll cover it but what makes a crab a crab? They seem very diverse.
