They have dietary, nutritional, physical fitness, exercise info at their fingertips via the interwebs. They know. Huge part of the problem is that so many do not understand/practice moderation. Candy bar once in a while, no big deal. Same with anything else. It's the steady, consistent eating of crap that is the problem. Laziness absolutely is a big part of it as well.
