Why Some People Burn Fat More Easily During Sleep
Why do some people burn more fat during sleep while others remain dependent on glucose?
In this video we explores the science of metabolic flexibility—the body’s ability to switch between glucose oxidation and fat oxidation depending on feeding, fasting, activity, and sleep.
We examine how mitochondria regulate fuel selection, how insulin and glucagon influence overnight metabolism, and why metabolic flexibility depends on the body’s ability to transition cleanly between fed and fasting states.
Topics covered include:
• metabolic flexibility
• mitochondria and fuel oxidation
• insulin and glucagon signaling
• CPT1, PDH, PDK, AMPK, and PGC1-alpha
• lipolysis and fatty acid oxidation
• the Randle cycle
• mitochondrial dynamics and mitophagy
• circadian rhythm and sleep metabolism
