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?

So much misinformation in the replies. Here are some hormones that can cause you gain weight and what they do:

– **ghrelin**, **leptin**: People can have imbalance in these hormones causing them to feel much more hungry and hence eat more. Some people produce no leptin or have resistance to it making them essentially always hungry.

– **estrogen**: Controls fat deposition and can cause people gain weight even if they eat the same amount of food

– **insulin**: Controls how much nutrients can be absorbed by your cells for energy. Imbalance or resistance can cause blood glucose spikes and excess fat deposition.

– triiodothyronine (**T3**), thyroxin (**T4**), **TSH**: Control your metabolism which can cause you burn less calories from the food you eat and store the rest in fat.

To make things worse estrogen and leptin can be produced by your fat tissue which means the more weight you gain the more imbalanced your hormones can become.
