Lifestyle tips

Hi everyone! I know that exist different types of bellies some like a baloon and others like jelly, (I think it calls belly rolls). Is this for genetics or for the feeding? How can get the belly rolls? What things is necessary to eat?
Thank you! And I´m sorry if I write something bad, I´m learning English.

Thank you so much!

I am a guy whose belly got round as typical but I much prefer soft bouncy fat with a flat belly. Guess you get what you get. Only 190 lbs but I’m not sure gaining will give me that kind of fat. Would love a fat hanging roll.
