When I was your age, I would eat non stop. Unless I massively overate I wouldn’t gain weight. It was tough to put on muscle when you have to over eat all the time. If I got lazy and didn’t over eat for a week, I’d lose weight.
Now I am more towards the middle. I can get fat, but I have to watch it. Ate really bad for like 2 years. So nows the time to get things under control before I get diabetes. And now you know how skinny people become diabetic, they can graze on sugar all day long and not get fat.
Yea some people have that body type I’ve noticed throughout my life. My brother is like that, very hard to put on weight and can eat junk all day, my grandpa on my moms side even at 80 he’s like that as well, those types of people at least from what I’ve seen almost can’t get fat even if they try, literally
