Fed vs Fasting Metabolism

Join Dr. Mike in this insightful video as he delves into the fascinating world of metabolism. Discover the intricate biochemical processes that occur in our bodies after we eat (fed state), and gain a deeper understanding of how these processes change during periods of fasting. Topics include; glycolysis, gluconeogenesis, glycogenolysis, ketogenesis, lipolysis, glycogenesis, krebs cycle, oxidative phosphorylation, and more!

Unbelievable depth of knowledge. I'm just here as a gym bro trying to understand glycogen depletion.

Thanks a million to u, Sir, from a medical student from Myanmar.

[@IM.MEDICAL]

Such a nice review! Thanks a lot!

[@gianinarockwell2938]

wow I understand this process way better compared to my nutrition class that covers 3 chapters of that in the online book... thank you!

[@DrMattDrMike]

Glad it was helpful! 😎

[@Amaralivilava]

I LOVE YOU. literally didn't even need to review other mechanisms because of this video

[@skonteti]

Mike you explained it so well, kudos to u.

[@Youthariseafrica111]

Thank you Dr. Mike.

[@ahmedalshabani-yt6ub]

thanks alot dr i have been writing dr mike and fasting yesterday and look what i got here i am really lucky

My takeaway from these related videos is that gluconeogenesis can produce enough glucose such that you do not need any external carbohydrates in your diet?

Great mini lecture 🙌 very informative thank you

[@josephpiskac2781]

Wonderful lecture thanks!

[@Jake0405]

we need to protect this man at all costs

[@jora8517]

W O W you've done it again !

[@simba_DIY]

Beautiful explain dr mike

[@jupiterlegaspi7528]

Bravo

[@inass5537]

As always brilliantly explained… million thanks doc!

[@dennispo4998]

what about fatty acid synthesis in the fed state, dr. mike?

[@juanph77]

Would be great if you gave a final summary or conclusion in layman terms. For example, “the most effective way to …..is through …..(feeding/fasting)…so that the body….”

[@DrMattDrMike]

I appreciate this point, but our videos are not designed to tell people how to do anything. This video is about the physiology of fasting - ie biochemistry and metabolism.

ATTENTION I SAW THE BIG YELLOW CAT WITH HAT AND THE SAD EYES HOW to replace Arreola do they repair or replace,can hydrogen replace co2 in the blood or lungs trying to fix a body . broken o2 smaller left heart chamber cannot measure flow volume laying on side had to lay at 45 deg. what might that mean?

[@JosephRogerson-l9z]

I have been using h2o2 in my condenser like 1/2 cap full after going in to public and mostly my grandkids they're always sick. Ear,eyes and throat infections.. and it keep me from getting sick yeah. I'm not a DR I'M not suggesting this is a treatment or anything other then self poisoning to heal not die.

Proves beyond any doubt that the body only requires about 5g of glucose at any given time throughout our lives. Humans consume 50 to 70 times that amount daily in total conservatively speaking. Why? when carbs are all non essential? Let our body make it's own glucose, which it does perfectly through gluconeogenesis and instead consume fats and proteins so we rely on ketones instead. Our preferred fuel source. Dr T thinks glucose is our preferred fuel. Please cite a single study clearly showing the human brain preferring glucose over ketones. Ketones are more efficient and use less oxygen resulting in less ROS produced and ultimately less oxidative stress. ketones can bypass the metabolic deficits associated with alzheimers disease and other neurological conditions and provide an alternative energy source, potentially improving cognitive function and reducing symptoms. Pre humans and human up until the agricultural revolution primarily ate meat and the associated fat of mainly large ruminants for 4 mill years. The carnivore diet is our most species appropriate and species specific diet.
