almost absolutely everyone has the genetics to look fit, provided they take care of themselves. Not necessarily MODEL shape, due to different bone structures and weight distribution. But definitely NOT obese.
But virtually no one has an excuse for having more than 15% body fat at any point in time, unless you have a preexisting condition that predisposes one to extra high levels of bodyfat (Which only happens to a real small handful of people, im talking way less than 1% here),
The rest of the people just aren't taking care of themselves or are miseducated about nutrition and exercises, or could care less, all i'm saying is do not dismiss yourself with an excuse, just admit that you have/had bad habits and accept it. And your Fedor arguments have no place here. He said himself that he likes to eat whatever he wants.
Genetics CAN be an excuse to an extent, but only for body shape and bone structure, it is RARELY almost never associated with excessive bodyfat.
Humans DO NOT naturally have EXCESSIVE bodyfat unnecessarily, bodyfat is a storage place for toxins, and it is a myth that bodyfat keeps you warm (IN HUMANS), it is a total farce. We just aren't built by nature to be FAT. It is a product of our lifestyles, not genetics.
Truth.
