>>649338If you mean legit fat girls, then fat is very insulating and they heat their surroundings less, but stay warmer themselves (just grab a girls chubby, with consent /out/ists, note they will be MUCH colder than the rest of her).
Also more weight to carry is always bad. Same goes for too beefy or fat guys. However high test girls that aren't overly beefy will be stronger, have a high endurance, and will also think more like men do. I read some study that high test female children gain skills similar to how men do in terms of cognition, and I think it's safe to say it's no stereotype men are better at being /out/.
