Thank you for your letter. I'm sorry if you feel I am disparaging exercise and a good diet but I'm not. I've written severally about the importance of diet and exercise for health and longevity. But it is true that these things can not reasonably help you change your weight. That is very interesting to me because so many people are misinformed about that specifically. If you want to read that dieting and exercise will help you lose weight, you can read that almost everywhere else even though it's wrong. I also think it is positive and helpful to tell the truth about what can't work.
