| Among the most popular forms of dieting is the South Beach diet, developed by Arthur Agatston of Miami, Florida. Dr. Agatston developed the South Beach diet for his patients with heart problems to lose weight. Since weight matters a lot in keeping heart healthy and traditional low-fat diets were too difficult for them to stick to, Dr. Agatston decided to create a plan that could help his patients. At first, the diet was just for his patients. Soon, thanks to his patients' success, the diet became the buzz in Miami, and eventually, word spread across the nation. This diet focuses on a healthy balance between carbohydrates (碳水化合物) and fats. It is based on eating a combination of "good" carbohydrates and fats, while limiting those "bad" ones. It is divided into three different phases. The first phase lasts for two weeks and is the strictest of the three. During this phase, you are asked to restrict (限制) all carbohydrates (good and bad). You are allowed to eat all types of fish, cheeses, eggs, and nuts, and a large number of vegetables. Most dieters can expect to lose between 8 and 12 pounds during this phase. During Phase 2, you are allowed to reintroduce some of those carbohydrates that are not allowed before. You are encouraged to start eating carbohydrates that have a low glycemic index (升糖指数). But you should keep in mind that the key is moderation (适度). Most people continue to lose 1-2 pounds per week. You continue with this phase until you reach your target weight. Phase 3 is designed to help you keep your weight. During Phase 3, you can reintroduce some of the carbohydrates that have a higher glycemic index, although again, this should be in moderation. Phase 3 is meant to be a way of life. 1. The text is mainly about .
