I’m not talking about while you’re eating, I’m talking about during the next couple hours after over eating. A food coma is absolutely the same feeling as a good high from some drugs. After eating a way too huge meal and laying on the couch i feel soooooo relaxed and floaty and drifting in and out of heavy sleep.
It’s a survival mechanism.
We human animals were designed to live in the wilderness with no available food. We had to constantly be on the search for food or preparing it in order to survive. And when we found food, we gorged on it because we knew that there might not be another supply of food later.
Humans lived like that for thousands of years.
It’s only been very recently that the majority of us had a steady supply of food. There are starving populations but not as much as there was in the past.
We are designed and conditioned to be starving because we are not supposed to have freely available food all the time.
Maybe in a few thousand years we will adapt to having food around all the time.
But right now and for the foreseeable future, we’re going to have problems with our diet and health all the time unless we really apply our knowledge and self control to maintain a healthy lifestyle.
Yes there’s also a mechanism in our brains that if a food is high enough in nutrients like calories, fat, etc. we don’t feel full and just keep eating. In the past such sources were few and far between, so when one came upon them, we needed to eat as much as physically possible. The issue is, these days we have a lot of food like that. Our brains can’t handle it, so we overeat very easily.
