Dr. Dean Ornish is known in the medical field for his work in reversing coronary artery disease with diet, exercise, and meditation—the same approach he recommends for weight loss. In his 1993 tome, Eat More, Weigh Less, he outlined his model for a low-fat, vegetarian diet. Centered around fruits, vegetables, and legumes, only 10 percent of calories come from fats. Meats, oils, nuts, and alcohol are forbidden.
