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

Question

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?

I think it’s that bad food is stopping the body from following its natural fat path. Fat should store in your buttocks first but with the food we eat it’s storing at the belly. The toxins in food are stopping the body from processing fat properly.
