Your body / unconscious brain is perfectly capable of - making you intensely crave specific calorific foods, - making you prefer the taste of higher-energy over lower-energy foods when offered a choice, - demanding your gut absorb more of the calories you normally consume, - making more frugal use of the calories you normally consume, - throwing you into hibernation mode, making you sleepy, lazy, and disinclined to move.
