Eating a lot without gaining weight: satiety, according to a forum user

The skinny person who eats a lot and doesn't gain weight: satiety, according to a forum user

Three dinners on the table. Four lettuce leaves with a piece of cheese. A salmorejo with egg and ham. And a dish one participant describes as burrata with olives, anchovies and some cold cuts. These are the meals shared in a debate about people who eat a lot and don't gain weight. The thread raises a suspicion: either the skinny person is lying, or their body works differently.

Why do some people eat a lot and not gain weight?

Feeling full is a sensation, not a quantity. That is what one participant argues: a dish that tastes like a starter to someone who is overweight fills up a skinny person because their stomach sends the fullness signal sooner. Under that logic, the person who eats a lot without gaining weight neither eats that much nor looks like they do.

Against that, another participant defends that the advantage is real: skinny people would eat whatever they wanted without their weight moving, and maintaining that weight takes less effort than losing kilos once they have been gained. The discussion remains open: nobody has weighed the portions.

What changes with age

That is what several participants maintain: from a certain age, the body puts on belly fat even if the rest stays the same. As the conversation goes on, some say they have dinners of that kind, with fat and no carbohydrates —meat, eggs, white sauces— to keep it from happening. And another claims he has never had a belly in his life.

There are also those who put figures on it: one participant says he weighs 77 kilos and calculates he is two over, and that his record was 92. Another says quitting smoking added 8 kilos, which he then gradually lost. No miracle and no excuse: bodies that go up and down.
