If it was sedentary lifestyles and plentiful food alone that caused the obesity epidemic, then it should have taken off in the 1950's.
My guess is not the abundance of food, so much as the nature of food now vs. 1950s. Now it is all processed crap. Few people actually cook real meals from raw food anymore.
