does heavy food make one lazy?

If you take heavy food during work the blood flow to the brain gets slow because our system is already working on the process digesting and hard to concentrate properly on your work, that is why you feel sleepy.Take a break for at least 20 minutes and refresh yourself.

yes..digestion requires a lot of energy and a heavy meal puts an even bigger load on your body. that's why people pass out after a big Thanksgiving meal.

I believe it's really true. I experience that also I feel sleepy when I'm full... I have no choice but to sleep immediately haha.

According to science heavy food does indeed make you sleepy.

I agree! Eating a lot of carbs and greasy food will definitely make you want to just lie down or curl up in a chair. I think it has to do with needing more energy to digest these kinds of food. The more complex a carbohydrate is, the more enzymes are needed to digest it. So, instead of going to the brain or heart, our cells go to our stomach. Just my thought though I could be wrong. :)

I think that is true, knightrider. They used to say you should have your biggest meal at breakfast, a medium one at lunchtime and only something light before you are going to bed. I think big meals do bog you down a bit and make you lethargic. A piece of fruit would be a good idea in the middle of the afternoon.
