No surprise, TBH. For thousands of years prehistoric humans didn't eat similarly sized meals N times a day every day. They ate whenever and whatever they could hunt/catch. Which means huge meals after days/weeks of hunger only to have days/weeks of hunger again. No wonder our bodies are well adapted to such irregularities.
