Metabolism of starvation/fasting =/= low carb diet

The Biology of Starvation (intro)

The Biology of Starvation: Renal Gluconeogenesis

[Patron link]

One of the major [obvious] differences in metabolism between fasting and low carb dieting is nitrogen metabolism… because you’re eating protein on a low carb diet, not so much while fasting. During fasting/starvation your body tries to downregulate the urea cycle because you can’t really afford to be ‘wasting’ amino acids/protein. I bet you never thought about the muscle-sparing effect of fat-derived fuels like that!



“Glucose production in starvation” is important because you need to make all of it and reduce the use of it.
