People eat poorly, people don't want to learn what to eat, people don't want to be told they can't eat certain things that taste good, and people don't want to take the time to learn how the body works. And, people do like to blame genetics and age because then they can keep eating the crap they eat and make believe that the problem isn't their fault.

And, it's actually insulting to me to have people say I'm thin because of my genetics and I "got lucky".

People still think fat is bad for you and a high carb diet is good. So people will continue to get fat.
