eli5: Why will the body continue to store excess fat to the point where it jeopardizes the person’s health?

2.16K views

I understand food wasn’t always so abundant, and humans were well served to store excess consumed energy as fat for later use. What I don’t understand is why the body keeps storing fat to the point where a person becomes morbidly obese and it puts their entire health at risk. Why isn’t there a point where the body just let’s the extra calories pass through without saving for later?

So, lots of answers revolve around evolution and how our ancestors never needed to burn excess. Is it possible that some point in the very distant futre we will evolve to do that?
