He made a little bit of a binary statement, either you have it, or you don't. You don't read well, as I, almost immediately, did tell him that we differed slightly in that nothing is all nature or nuture. Meaning: these two things almost always work in concert with each other. But, I did agree with his "gist". People are born with higher propensities to do certain things. It seems a silly thing for you to disagree with, but to each his own. And, people do get fat due to their "genetics", not rather than their lifestyle, but in conjunction with their lifestyle. Whether you want to believe it or not, there is a genetic predisposition to weight gain:

Maybe you don't trust a little school like Harvard, but it seems legit?
"Genes are probably a significant contributor to your obesity if you have most or all of the following characteristics:
- You have been overweight for much of your life.
- One or both of your parents or several other blood relatives are significantly overweight. If both of your parents have obesity, your likelihood of developing obesity is as high as 80%.
- You can’t lose weight even when you increase your physical activity and stick to a low-calorie diet for many months.'
Of course, no captives walked out of Auschwitz fat, either. So, what we consume is relevant, as well. But, your understanding is so superficial, it really isn't worth going on.
Do you REALLY think that you can teach anyone to jump as high as a world-class high jumper? That's just a skill? There is no innate genetic propensity?
