What causes "food coma"?
3 doctors weighed in across 2 answers
Redirection of blood: Even though there is a dramatic increase in blood flow to the stomach and intestines after a meal (proven by ultrasounds) it is thought that it is the increased parasympathetic nervous system activity (opposite of the fight or flight sympathetic activity) which causes the feeling of lethargy.

Bodily hormones: The body shifts from intense hunting for food to calm digestion following a heavy meal. This is the result of hormone shifts within the body. Some persons have more dramatic hormone shifts than others. Some foods induce these hormone shifts or even contain hormones that help shift body function. This is especially prominent at thanksgiving! alcohol adds to the effects.
