How to Control Your Metabolism by Thyroid & Growth Hormone

This episode I discuss metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanism and tools grounded in specific mechanisms are discussed. Thank you for your interest in science!

Hi professor Huberman, just informing you that I am a 42-yo female, overall healthy, healthy and stable weight, since 7 years I have been doing a clean-food low-carb/keto diet (under 100 g carbs/day, occasionally cycled out around 100 - 150 g/day) combined with intermitent fasting (at least 18 hours of daily fasting). 14 years ago have been diagnosed with Hashimoto´s, since childhood suffering with multiple food and environmental allergies, atopic dermatitis. Since on the low-carb + IF, all health issues significantly improved: all allergies gone, atopic dermatitis gone, Hashimoto´s improving (aTPO and aTG low level now) and currently categorized as subclinical, good quality hair/nails/skin, good sleep, feeling no hunger, no cravings, no exhaustion, tons of energy, cognitively superb. Since on low-carb, my menstrual cycles are perfectly healthy, fairly regular, mild flow, mild to no pain, every cycle ovulating (had been on birth-control for 20 years before the low-carb). So in my case, the intervention works.

[@lj32920]

@@natashacro8148 He didn't mention Hashimoto's by name. He made oblique reference to underlying hyper- or hypothyroid condition. By and large, the most common hypothyroid condition is Hashimoto's. However, as wonderful as it would be to be able to fix Hashi's through diet alone (and many people tout that it is possible), Hashimoto's is an autoimmune condition. So it's not that Hashi's patients are low in something. Their own bodies are attacking their thyroid tissue. There are things that can help, and there are also naturally derived medications, as opposed to synthetic, but medication is a godsend for those with an actual thyroid autoimmune disorder (me included).

I’ve been struggling to piece together a recipe to regain my energy. I’ve tried many different ways of eating and exercising over the decades and most recently did keto eating less than 16grams of sugar per day.

Hey Doc! Just finished this episode, thanks again for the wisdom! May I please ask you to cover 2 things eventually as I’m sure I’m not alone in this: 1) A further dive into sleep apnea, especially for those of us who have tried weight loss and despite reaching a healthy weight-to-body composition ratio, and the effects of the CNS on sleep apnea as this is something not enough specialists out there have yet mastered. Also, 2) why our body shivers (kind of like when you have a surge of relief for a quick 1-2sec after urinating, sorry for the example but best thing I can think of) when we take a REALLY deep breath; I usually take the breath in and once I can’t take in anymore, as soon as I start breathing out, I get that shiver almost 99% of the time. I have a history of anxiety/panic so the logical presumption here is that the body is just not used to so much oxygen as it has been used to being tense/reduced oxygen intake? Could this deep breathing exercise be used for addressing traumas? Thanks! 🤙🤙

@@isaacakaisaac I cannot remember, but it's in the context of fasting, sodium levels drop, coffee drops it as well, so people who do IF and drink nothing but coffee until noon-2 like myself and Dr. H, a little bit of salt water (I do it around 10-11am after coffee is peaking but who knows what works best) balances you and can get rid of a weird feeling he says he thought was something else until he tried the salt water trick. I definitely feel it works, if I wasn't drinking coffee, wasn't intermittent fasting, wouldn't have a need, enough salt in my food. Some people drink lemon and salt water, I know they had a machine that dispensed that at Twitter headquarters, I think the acid suppresses hunger, gives you something, but again, for those who have decided that this schedule of eating and caffeine works for them, def not for generally anyone! Especially if you have hypertension / a diet already too high in salt!

[@andrewconnor4429]

@@EZMotion101 Humans can't rehydrate from saltwater because you need lots of water to flush out that much salt. But adding a half a teaspoon isn't much different from a normal meal's worth in your food and flavoring. Sea water would be more like 3 teaspoons in a cup, which would be gross lol

Thank you man so much for this! Sending u my gratitude squishies today. ☺️ 💯❤️ Ur passion and ability to express knowledge in a way that is so well received and comprehended but doesn't squash my sense of curiosity to dig deeper into a given subject, rather the opposite... I find in all the episodes so far I've thought "Aha! That could be why? AND I need to know more, so interesting! AND But what if...?! Then more research and reading happening." LOVE IT! Plus, ur farther research suggestions and where to get free educational stuff are very much appreciated and can't get enough, LOVE learning!

Fascinating to see specific evidence for my experience in this space. I started eating late at night during pandemic. Get up at midnight, eat more calories and carbs. I was convinced i was messing up my glycemic system: became more thirsty, tired, urinating frequently. I gained weight, and unique to me, body fat. This is contrary - a complete opposite food habits and metabolic-affecting behavior - to lifetime habits prior. For decades people have asked me why i look younger and fit than my age. I thought it might be because i ate 1 main meal, snacked on nuts, vegetables, and at 39 yo cut out gluten and dairy, on advice of a trainer (my first ever and an invaluable person in my life). For my singular goal to build muscle and stability around my joints, he taught me HIIT olympic weightlifting program. 5 years later I learned to rock clmb, doing late night sessions daily 8pm-11pm. My food habits in 20's/30's: maybe glass of wine early evening with friends, feeding my children + meat, veggies. At 9pm daily, after putting kids down, I ate salad: HUGE bowl of lettuces, salt, olive oil, vinegar -- my comfort food. In pandemic, i began eating like "everyone else" -- late meals, extra meals, and high carb meals. I'm 2 years late to this podcast. Fascinating. I dont know if anyone reads these comments. but thought id share that it is 100% consistent with my unpleasant pandemic "experiment."

I learned the hard way of how keto messed with my thyroid and you just explained it, but I knew that’s why. I developed nodules and hair loss so I stopped and yes gained a lot of weight. I had a procedure extracting fluid from the nodule but in three months it grew and larger so I decided to remove my thyroid. Since then I have started losing weight with the consumption of various foods for macro and micro needs and still working out the thyroid medication levels, and I’m confident I have narrowed down the mcg that works for me . Thank you for the wonderful information!

[@But_WhatIf]

I am 25 and was diagnosed with hypothyroidism (Higher than normal TSH Levels, also dry skin, brain fog etc.). If I understood right going on a keto diet would be a bad idea? Because at one part ( 45:17 ) Andrew said Keto diets slightly lower Tyrod levels, which means tsh goes down? Wouldnt that be a good thing for someone with hypothyroidism? Or did he mean the Hormon so L-Tyroxin?

[@iss8504]

@@But_WhatIf i am on keto and i had had my thyroid removed. My meds have not changed at all, same as they were prior to keto. If anything i feel so much better. The low carb community thinks that lower thyroid hormones might mean your body is more efficient with less.

Great Topic, I've been interested in Growth Hormones for quite a while. I am hoping to see an exclusive podcast on Addiction and Maybe a small section on Nootropics (Bacopa, R-modafinil, Ginkgo Biloba etc) in some other video.

Fasting increases the most HGH according to dr. Eric Berg. Check his KZbin channel, he has tons of info as does dr. Jason Fung. But don't just dive into it, make sure you do it gradually and do it right.

I watched this episode in October '21. I speculated my thyroid had been underactive due to fatigue, puffy face and inability to lose a bit of weight gain. Rather than move on speculation alone, I had my thyroid tested on 11/2/21; my TSH was high at 4.6 mIU/L and T3 low at 23%. I supplemented daily with brazil nuts, first with 5 to 7, then down to 3, over the course of the next four months. On 2/24/22 I began to experience odd symptoms, that lasted for nearly a week. In that time I ceased consuming brazil nuts, speculating TSH was down and perhaps T3 production had increased into an unhealthy range for me. While I was unable to test my thyroid levels in the midst of the symptoms, I was able to test yesterday (3/7/21 - four months from baseline) and discovered my TSH has lowered to 2.1 mIU/L and T3 has risen to 31% (35% is the upper limit). The feedback loop appears to indicate There is now enough T3 to communicate to my pituitary to ease up on TSH production. Which is good. My question is, if T4 is inactive, why do some health practitioners rely on it for diagnosing? I spoke with my HCP and the notion too much selenium via brazil nuts was essentially dismissed. This is one reason why I am 100% for being our own health advocates, but need well-informed guidance from practitioners willing to explore more naturopathic avenues. Thank you for the information and sharing with society information we can all benefit from!

Because higher glucose 2 hours before sleep may inhibit growth hormone.. Im guessing that 1 beer before bed would also have that undesirable effect. Thank you for bringing us helpful information to adjust our behaviors. It's so much easier to change a behavior when you understand the "why" behind it!

I definitely agree, much easier to make the change when you fully understand WHY you are doing it.

[@michellekalsi2661]

Thank you su much as always for your podcasts - I look forward to them every week! I do have a comment regarding your very frequent disclaimers for people to "talk to their doctors" regarding nutrition. Doctors are actually not the best choice when it comes to discussing nutrition; they have very little, if any, meaningful nutritional training in medical school, and often do not keep up with current nutritional research. I wish that well-trained nutritionists were more accessible and also covered by insurance, so people could get good quality guidance on how to optimize their health through nutrition! Thank you again for your well-researched and thoughtful content!

Firstly, thank you for all of the awesome content you continue to provide! Secondly, question: what is the ideal rest period between sets for optimizing HGH production? Edit: also curious: what are your thoughts on fasting relative to HGH production?

[@Zach-lg5ql]

You mentioned in previous episodes how lower temperatures are important for deep sleep. This deep sleep, however, increases GH, which is also increased during wake with higher temperatures. Should we still keep the bedroom cool for SWS/GH and warm up the body during the way to optimally stimulate GH?
