I can't quite understand if you are agreeing or disagreeing with me...

You seem to be restating my point as if you are contradicting my statements.

> People living in country side & eating from organic farming, they're doing alright (similar to our closest ancestors), but that's beside the point

Maybe ( I would love to see some sources for this assertion). But even if I give that to you, you basically saying that modern environment are somewhat obisidigenic... which is what I was saying.

> Cultural change over 2/3 even 10 generations will not significantly alter your biology.

Okay... same., still just restating what i have said.

> they possibly cannot have effects on your decisions about what you eat and how you spend your time right?

They can and they do... let me introduce you to lead in paint and in the environment...

> particularly referring to obesity caused by over eating

All obesity is cause by over eating (all most by definition) the point here is that over eating is not cause by lack of will power or poor decision making
