Why am I so tired after I eat lunch?

Answer by  Tranwreck (279)

It is more than likely that you are eating too much. Eating too much causes your digestive system to work extra hard and may cause fatigue. Try eating less.

You are so tired after you eat lunch for one very important reason.Your body sees digestion as the most important function it can undertake.

If you eat an especially large lunch, then your body will need more energy to digest it. So your body sends more blood, and therefore more energy, to your digestive system to break down the food you just ate. Try breaking up a larger meal into one meal and one snack.

A lot of times if you eat or drink something heavily sugared, you will have a "crash" shortly afterwards which will make you very drowsy.

Sometimes when you eat you might feel tired because your body is using more of your energy to digest the food you have just eaten.

You probably had a meal high in carbs and sugar. This causes your blood sugar to rise higher than normal, which causes your pancreas to make more insulin. This causes the release of a protein called tryptophan into your bloodstream. Tryptophan is then converted into seratonin, which makes you sleepy.

Your are probably eating too much, too fast. That can make me really sleepy if I do that. Try to slow down and maybe not eat as much at one time. I know it's hard to eat that when when you are probably given a certain amount of time to eat lunch.
