The New York Times has a piece today about a study purportedly showing that exercise doesn't lead to weight loss:
Exercise, it seems, should make you thin. Activity burns calories. No one doubts that. But few people, an overwhelming body of research shows, achieve significant weight loss with exercise alone, not without changing their eating habits.The key is the last six words above. You can't just exercise; you have to watch what you eat. Sadly, most people are going to stop at the headline, and conclude that because "exercise doesn't lead to weight loss," they shouldn't bother getting off the couch at all.
