ELI5: How does your body store and distribute fat?
gpt
When you eat excess calories from food, you end up with more sugar and fat in your blood (and lymph, for those who are pedantic) than your body should have. So your body releases a molecule called insulin (and a few other molecules) to signal some organs like your liver and fat tissues (known as adipose tissue) to start taking up those extra sugars and fats out of the blood. The liver stores both sugar and fat, and the adipose tissue turns the sugar into fat to be stored.

But not all fat tissue is equal; some have different receptors on them and so are sensitive to different signals. For instance, the sensitivity to sex hormones differs between fat around the belly and fat around the thighs, which means that men often have more fat around their belly and women more around their thighs. So the exact area where you store fat depends on which adipose tissues are being told to work the hardest and cleaning up the extra sugar and fat in the blood.

Does this answer your question? Feel free to ask for more information.
