Strange, every single source I can find blame diets and lifestyles, but you might be right and everyone else is wrong, we just "talk more about it"... you have a good source of copium my friend

It's easy to blame diets and lifestyles because you don't have to be specific, and if reality disagrees with your hypothesis, you can claim the victim didn't hold their lifestyle or diet right. Diet/exercise are the ultimate "fuck off" advice.
