The feeling of tiredness or sleepiness after eating a meal resulting in either zoning out or falling asleep. This problem can be solved by taking a nap or consuming any content that prevents sleep.
This problem often happens when a person wakes up early in the morning to eat breakfasts and then waits till noon to eat lunch. The effects of food comma can be found fifteen to twenty minutes after such person eats lunch.
