Its a nice sunny day and youre grilling out with friends before the big game. You proceed to gorge yourself on grilled meat and all of the yummy side dishes brought by others. You then head over to grab a nice comfortable seat for the game, preferably something soft that reclines. Before you know it youre feeling lethargic and begin to doze off. Where there was once vigor and anticipation for the game there is now lifelessness (aside from some potential snoring here and there, of course). What you are experiencing, or stricken with, is postprandial somnolence, the scientific term for food comathats right, a food coma is a condition recognized by science!
In response to your gorging on all the various delicacies within sight, your body begins to go through some rapid changes that affect your in game viewing performance. When massive amounts of food hit your stomach and small intestine, your body begins to prepare for the arduous task of digesting it all. All of those carbohydrates you consumed and much of the protein is subsequently turned into glucose in your bloodstream, which requires the hormone insulin to usher it all out.
