Personal Note: I've been so inspired by the "Go Active" adult happy meal, I'm going to start a personal experiment. I'm going to do the same thing I've been telling patients who want to lose weight for years - eat less and exercise more. Starting today, I'm going to keep a record of my calorie intake, shooting for 1200 calories a day, and of my walking - shooting for five miles a day.

I know it works, because I've done it before. It just takes a degree of obsessive-compulsiveness that's hard to maintain. And once you stop being obsessive about counting everything, backsliding is inevitable. It's so easy to convince yourself that you didn't really eat that many calories today, so it's OK to have that extra cookie. Or that you really did do a lot of walking at work so it's not necessary to get on the treadmill or go to aerobics class. We'll see how it goes. (But I'm not going to go on a McDonald's diet. It's too expensive. And boring.)
