I am confused as to why the human body has so many regulation mechanisms, yet seems to fail many of us in excess weight gain. Why can’t the body just increase the metabolism/heart rate in overweight people, to help burn off the extra calories?
In: Biology
Because we evolved in a world where famine was much more common than surplus. As a hunter/gatherer we had to make good use if every calorie. There hasn’t been time or enough of a issue to make it change.
