Integration of metabolism: a metabolic diary Flashcards
what are the metabolic states?
fed
postabsorptive
fasting
starvation
fed state
3-6h after meal
postabsorptive state
3-6 - 12-18h after meal
fasting state
18h-2d
starvation
Fully adapted state of food deprivation lasting up to several weeks
what happens in the liver in the post absorptive state?

Lactate uptake
Glycogenolysis
De novo glycogenesis
Triglyceride synthesis
FA ox
Glucose release
what happens in the muscle in the postabsorptive state?
Glucose uptake
Glycogenolysis
Triglyceride synthesis
FA ox
Transamination of create alanine
Alanine release

an energetic day
Healthier day with a low-energy, mainly corn breakfast
h later subject goes for long slow jog
