Simply discrimination.
I'm not trying to be sensitive, but in our information age, anyone should know better that bio-genetics should be considered as well as informing about societal impacts of capitalism and sociology. And no one should be blaming with victim-hood thinking, my point is no one should be bashing on anyone without offering serious elements to help someone succeed.
I try to help people understand choices and consequences, but I also respect the power of influence. Not even linking to a site on nutrition aid or obesity, that's shameful.
Eating so much, may have more to do with eating the right foods that are healthy, or what times of day food is better recommended to be eaten on a timed schedule. And exercising without proper moderation can be harmful, especially if a certified trainer is not involved, to help oversee any health risks. Don't be surprised that not many people know about this kind of stuff, because they just haven't simply been exposed to it, or do not know where to find this kind of information.
Anyway, I'm sure some people on this forum took a punch in their esteem just reading your insults and poor judgement, Op. Better luck next time at motivating the masses.
