Dean Ornish's "Eat More, Weigh Less" is the only well-known vegetarian diet book on the market. Originally designed for people with heart disease, Ornish's diet has been studied extensively and is recommended by some experts. Not only can it lead to weight loss, but several studies also point to it as a good way to encourage heart health. The diet focuses on whole grains and vegetables, and it's also low in salt and fat. Some critics think it may be too low-fat for some to stick with for a long period. In addition, users say the menus and recipes can be dull, and non-vegetarians may find that this diet is too drastic of a lifestyle change.
Ornish's newest book, \"The Spectrum\" (*Est. $12 for the book), follows many of the same principles and earns one recommendation from our review sources. Those who don't think they can stick to a low-fat, vegetarian diet may be better off with an established program like Weight Watchers (*Est. $30 to join, plus weekly fees), which is also vegetarian-friendly.
