Please don’t answer this question if you cannot answer it logically.

I notice some people need to exercise a lot more than others to keep slim.

Thousands of years ago, when food was scarce and everything was about manpower (hunting, running away from predators, farming), if you were equal to a skinny person today who has to eat a LOT of food(but still be skinny), wouldn’t you have problems in such an environment?

I am guessing really skinny people high extra high metabolisms, but would this be a bad thing in the primitive times(oppisite to now), since there is such little food and they need lots of food to survive, they would not be able to produce the muscles they needed.

Anyway, whether this is true or not, skinny people seem a little better off today since we have TOO much food, just the opposite to before. But it wont stay that way for long when we find cures for obesity and eating disorders.
ps Just in case some people misinterpret this, am not asking if it is superior to be skinny or fat, since no trait can be “superior”, but only superior in its current environment(for example, if you lived in a place where aliens killed people with beards, and you had a beard, you would be “inferior” and bearded people would disappear through natural selection).
pps My question doesn’t seem that clear. I should have said:

Were people who need to exercise more(to keep slim) disadvantaged in the wild hundreds of thousands of years ago?
