If most people in the developed world have excess fat storage, why do our bodies signal hunger after only a few hours after eating?
In: Biology
Your body is tuned to grab the calories while they’re available, because for almost all of history getting enough food was a struggle. Putting on too much weight occasionally is less unhealthy than starving to death because you don’t have enough reserves, basically.
(Trivia: Even with organised farming and so on, only 700 years ago a British writer described the feudal Lord of the Manor as “the man who always has enough to eat”. Whole populations having lots to eat all the time is a VERY recent thing.)
