Answer 1

Evolution did not prepare our body for restaurants and supermarkets. Our bodies are designed for foraging, scavenging, and hunting. We are not supposed to have guaranteed meals multiple times a day. Our bodies react like our next meal is never certain so we need to store up when we can find it to prepare for the times when we can’t.
