ELI5:How come some fat people have loose rolls but others have really tight guts?

You can be fat and muscular. The *tight gut* is typical for men who are overweight, and at the same time have plenty of muscles keeping their belly from flabbing all over the place. Manual laborers who do a lot of heavy lifting etc. tend to have a tight gut, overweight office drones tend towards loose rolls.
Women's bodies follow slightly different rules for fat storage and muscle placement. But again: If they are overweight yet not flabby, the answer is muscles.
