How do some people gain weight but not get fat?

I was just wondering how some people are always slim and look the same but they're gaining weight and shedding it off and still looking the same. How are slim people heavy? I don't mean muscular slim people but just slim people.

How to Fast to Lose Weight

Recommended Answer:

If I understand the question correctly, It's the metabolism. The higher the metabolism is, the easier it is for food to just go right through them. Some people where born with it. Some may have not started to eat real food till the age of 2 or 3 years old (which helps). And other's earn it but staying active daily.Whether they're born with it or not, as a kid, most of them stay active anyways. Even later on in life, if they're not very active, that metabolism they had is still trying to work in them, that's what keeps them slim. They may start growing a little belly on them, but they don't blow up as of somebody who was born with a low metabolism and/or hardly ever exercised. But slowly, that metabolism dies off and becomes low if they just gave up being active and ate whatever, then they will blow up within 10 years or so.
