You probably just excrete excess calories, where other people with your caloric intake would store the excess calories as fat. Also you might become restless when you eat too much and you’ll instinctively start shaking your legs even when sedentary to burn those excess calories. Or maybe you’ll start pacing or you’ll get hot and burn calories that way. This is just favorable genetics. Also, muscles take energy to maintain. As you lose muscle as you get older your burn rate will also go down because of that. Finally, most people eat at set times even when they’re not hungry and snack outside of set times when they are. Needless to say this automatically results in overeating. Skipping meals when you’re not that hungry is great but harder to do when you live with other people.
