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

Drugs, hormones and most illnesses make people fat via three main mechanisms

1. Hunger and they eat too much which makes them fat.
2. Reduce energy expenditure, so they burn less calories, leaving more to turn to fat.
3. Water retention which increases weight but doesn’t make them “fat”.
