sometimes i guess. to varying degrees. i saw some of the answers here and some ppl are saying low income ppl don't have access to healthy foods. Poor ppl are skinny usually that's the whole thing about being poor. i was poor & a rail but when i got older & more money i got heavier. Also even if your neighborhood was nothing but Mcdonalds it doesn't mean you need to eat the whole right side of their menu everyday. I've heard the genetics argument but i also know a guy who's parents are 300lbs each his grandparents were fat & he hits the gym hardcore cause he knows he can end up that way. maybe blame isn't the right word but it's NEVER beyond your control
