Ever wonder why we eat 3 meals a day?  Is it a social convention or a biological one?.

Chris as we are pondering life , who/why did we come up to working X hours a day or x days a week. Maybe as we evolved from Hunters and gathers this came to be. John Burns question maybe....Do we eat too much as for millenium humans struggled to have food to eat so we unconciously over consume even though we know we have another meal tomorrow


I believe we do on certain foods.

Meat protein and fat not so much so. Satiety kicks in and tells us we are full or had enough.

Carbohydrates yes. One line of evolutionary thinking is that the fruits and other starchy things were available mostly in the fall of the year. The time to fatten up and get ready for a long winter when food would not likely be as plentiful. So the carbs kicks in a foraging and over eating portion of our evolutionary brain. Kind of like bears gorge themselves on berries to fatten up and get ready for winter. At least that is one theory. It may or may not be correct. But it sounds feasible and reasonable to me.

With today's modern food system we essentially have no "winter" or in other words food scarcity. We can have an orange, banana or almost any other exotic fruit out of season in the middle of the winter. Grocery stores are full of all kinds of food year round. That would have never been the case as recent as less than a couple hundred years ago. A mere "second" in the time line of genetic evolution.
