What is the South Beach Diet?
As director of the Mount Sinai Cardiac Prevention Center in Miami Beach, Florida, Arthur Agatston, a cardiologist, knew that his patients could improve their heart health by improving their diets and losing weight. With dietitian Marie Almon, he developed the South Beach Diet, which has reached worldwide audiences through the best-selling book The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss.
The South Beach Diet uses the glycemic index to identify “good” and “bad” carbohydrates, ranking carbs according to their potential for raising the level of sugar in the blood. The lower a food is on the glycemic index, the less effect it has on insulin and blood sugar. Heavily refined sugars and grains–the bad carbs–rank high on the glycemic index; the body digests them quickly, causing sudden increases in blood sugar that lead to food cravings. Beans, vegetables, and whole grains are good carbs–low on the glycemic index, nutritious, and satisfying.
The South Beach Diet is a balanced diet that includes all major food groups. Vegetables, fruits, whole grains, and lean protein are the mainstays of the diet. In addition to replacing bad carbs with low glycemic carbs, the diet replaces transfats with foods rich in unsaturated fats and healthy omega 3 fatty acids. Lean red meat and poultry, nuts, and oily fish such as sardines and salmon, feature heavily in the South Beach Diet. There is no calorie or carb counting or strict portion control in this diet. Dieters eat three meals a day, plus snacks—enough to satisfy their hunger.
Cost of the South Beach Diet
For individuals who choose to use the South Beach Diet book and prepare their own foods, there is no additional cost to follow this diet. The South Beach Diet does offer a wide array of prepared foods, which typically cost from $300 to $400 a month, but you can follow the diet with foods from the grocery store.
How the South Beach Diet Works
The South Beach Diet has three phases. The first phase, which lasts two weeks, is intended to eliminate food cravings by stabilizing blood sugar. You follow a strict diet that bans sugars, processed carbohydrates, pasta, grains, fruits, alcohol, and starchy vegetables such as sweet potatoes, white potatoes, winter squash, beets, carrots, and corn. The diet for the first two weeks emphasizes satisfying and nutritious foods, including lean proteins, high fiber vegetables, reduced-fat dairy, and foods with unsaturated fats like avocados, nuts, seeds, canola oil, and extra virgin olive oil. The first phase is a time of big weight loss, mostly from the loss of water weight.
The second phase lasts until you reaches your weight goal. Carbohydrates are still restricted, but not as severely. The second phase brings most fruits and vegetables and some high-fiber grains (such as brown rice, rye, and whole wheat) back into the diet. You can drink a moderate amount of alcohol. This is the long-term weight loss phase, during which you lose weight steadily. If you want to lose ten pounds or less and do not have food cravings you can start the South Beach Diet in this second phase.
The third phase of the South Beach Diet is the diet for life. You follow the basic principles of the diet: eating frequent small meals of balanced, nutritious foods to avoid hunger. Fruits and vegetables excluded from earlier foods (such as beets, corn, white potatoes, watermelon, pineapple, and dried fruits) are now allowed in moderation.
Benefits of the South Beach Diet
Successful followers of the South Beach Diet eat a balanced, heart-healthy diet. The diet includes all major food groups. By following the diet, individuals learn the principles of healthy eating. Unlike many weight loss diets, the South Beach Diet emphasizes healthy eating and long-term weight maintenance.
Dieters have options for their meals: They can buy prepared South Beach Diet meals or use the basics of the diet to make their own meals from normal foods found in the grocery store. South Beach Diet recipes and meal plans, featured in the South Beach Diet Cookbook, are appealing and not difficult to follow. Plus, they save time because you do not have to spend time figuring out if the recipes fit with the diet.
The very restrictive first phase results in rapid weight loss, which can encourage dieters to continue with the diet.
Concerns about the South Beach Diet
Some experts voice concern that the diet oversimplifies the glycemic index and misleads dieters about the effect of carbohydrates on blood sugar levels. They say that other factors, including how foods are combined and prepared, affect insulin levels, blood sugar, and hunger.
The rapid weight loss in the first phase is from loss of water weight and can create an electrolyte imbalance in some dieters. Electrolyte imbalances can result in serious health consequences, including dehydration and problems with the nervous system, heart, and muscles.
Is it For You?
The South Beach Diet has been very popular with a wide range of people. It may be a good choice for you if you want a moderate low-carbohydrate diet. If you have strong food cravings, the initial, highly restrictive phase may help you overcome them so you can successfully lose weight.
The South Beach Diet is a heart-healthy diet with balanced meals. Before you embark on this diet—or any weight loss diet–you might want to consult with your medical provider to see if he or she thinks this is a good diet for you. If you decide to participate in the South Beach Diet you can always talk to your physician if you have any questions or concerns about your health or weight while you are on the diet.
