I listened to another interview on NPR that discussed a study of various popular weight-loss diets, including Atkins and Weight watchers. They found that every diet worked, for people who followed them faithfully. And every one failed for those that didn't.

If you lock someone in a dungeon and only feed them bread and water, even the most obese person will come out skinny!

Americans are very fortunate to have a choice of diet, and to have an abundance of good quality, relatively inexpensive food.
