How does someone get fat from having hormonal issues? Where does the fat comes from?

Question

As of my current understanding, you need calories to get fat, how can some hormonal issues lead to weight gain? Where does all the energy comes from?

Answer 1

The fat doesn’t come out of nowhere, it’s processed from ingested food like everything else. Hormones control how much of it is broken down, metabolic rate, how much organic compounds are turned into fat, behavior, etc.

There isn’t one hormone that controls weight either
