They may have a point when it comes to a more sedentary workplace--not that I buy that this is the cause of overweight/obesity, but a lot of people are probably less physically active at work than they would have been a generation or so ago.

Muscle bound jocks... I have to wonder if being a muscle-bound jock has increased in popularity enough to make much of a mark on obesity/overweight stats? Take a "normal" bmi person, or "overweight" bmi, add ten pounds of muscle, and maybe you've got somebody who's now shifted to overweight or obese.

There is some debate about whether or not people are actually eating less than they used to, or more.
