I think kids definitely don't get enough exercise and there is far too much junk food around. I am only in my early 30's, but as a kid we only had soda once a week, and snacks were parsed out sparingly by my mother. We rode bikes and roller skates, ran around, swam. [I did not gain a lot of weight until I was in college and my depression kicked in full force.]
Taking the vending machines out of schools is one good step, I think, but parents need to limit computer/TV/video game time and get kids moving, too. I agree with the dude in the article that said kids need to get more exercise.
