Why does the human body store fat endlessly?

Question

I have searched everywhere that I can think of.All I get is how to lose or burn body fat.Help!Please!

Answer 1

Man has evolved from a very harsh environment where food was scarce.  Every bit of energy was stored as fat for tough days ahead.

Now we have plenty of food  and so far we won't have famine soon (although ...) .

Our physiology does not know that so it keeps storing energy.

Answer 2

It is part of our mechanism.  The goal is to burn it faster than it is stored.
