ELI5: How does your body proportionately distribute fat/mass across your body? How does it evenly for the most part distribute to all parts of the body?

Well for one thing it's not even and a lot of this has to due with hormone levels. 


Estrogen will generally signal for more fat storage in the legs, hence women having thicker legs and posteriors.


Testosterone will favor the arms and upper body.


Cortisol will favor the stomach. See people with Cushing's for extreme example. 


Insulin the sides of the stomach. (love handles).
