I'm not sure how to link back to my own posts, so you'll have to check the archives from July 19 for my original post on this subject.
Josh Mankiewicz posted a followup to his article from last week about his Atkins diet success story. The followup piece mentions all of the e-mails he's received on the subject since the original piece aired. There are plenty of negative reactions to his story, both from people who, like me, think that Atkins dieters are slowly killing themselves with fat, and also from people who have gained weight on high-carb/low-fat diets and now think that doctors and dietitians have lied to them about the benefits of such diets. But there's not one mention anywhere about exercise playing a role in weight loss. I hate to repeat myself in this space, but I think I have to: you can't just change what you eat and expect to lose weight. You must exercise. You don't have to join a gym, buy expensive equipment, or hire a trainer. Go for a walk. You've got two legs, right? Use them. Often. Once you start burning more calories, you'll feel better, you'll look better, and these changes can be an incredible incentive to keep it up. It's worked for me.
Maybe I need my own infomercial, or at least a spot on Dateline, to make this point to people. Oh, that's right, I'm just an average schmuck. No one cares what I think.
