Eli5: Why do obese people store fat instead of having their body utilize the surplus of calories as extra energy?

538 views

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?

We do have regulatory mechanisms that help us keep at a normal weight actually. The metabolism does go up when you eat more, the hormone responses make you not feel hungry anymore, you get an uncomfortable feeling when being too full, you get a burst of energy that allows you to burn more. The body doesn’t really like change, so it’s trying to maintain always. If you are metabolically healthy it will be actually hard to gain weight at the very beginning of your overeating.

The thing is that with the processed diet that most of us have and the lifestyle we lead if you will usually get hormonal imbalances before you even get obese. Processed food is actually designed to make you crave it more, even if you are full. And then it’s a cycle it’s hard to get away from.
