The South Beach diet was invented by cardiologist Arthur Agatston. He developed this diet for his cardiac patients and he discovered that as a side effect of the diet they also lost significant amounts of weight.
South Beach Diet is not a traditional low-carb or low-fat diet plan.
The diet distinguishes between good and bad carbohydrates, and good and bad fats, and purports that by cutting the bad carbs out of your diet, you will lower your body’s levels of cholesterol and insulin, which will ultimately lead to weight loss.

Good carbs” are high in fiber or high in good fats, and have a low glycemic carbs, such as whole grains and vegetables, which take longer to break down, expend more energy as they break down.
Other preferred carbohydrates are those with more nutritional value than the alternatives. For instance, brown rice is allowed in moderation, but white rice is discouraged. When eating any carbohydrates, Dr. Agatston recommends also eating fiber or fat to slow digestion of the carbohydrates.
Good fats” are polyunsaturated and monounsaturated fats, especially those with omega-3 fatty acids. Saturated and trans fats are bad fats.

The South Beach diet has three phases.
In all phases it is recommended minimizing consumption of bad fats, such as saturated fat and trans fat.

  1. Phase I, which lasts two weeks, are meant to help your body a complete rest from fluctuating blood sugar and insulin levels. Dieters attempt to eliminate insulin resistance by avoiding high or moderately high-glycemic carbohydrates such as sugar and alcohol, candy, bread, potatoes, fruit, cereals, sweets, cake, biscuits. But the focus is on eating lean meat, chicken, fish, eggs, low-fat cheese, some nuts and olive oil.
    During this phase the body will lose its insulin resistance, and begin to use excess body fat.
  2. Later 2 weeks begin Phase II.
    Whole grain foods and fruits, Granary bread, wholegrain cereals and pasta and low-fat milk and chocolate and wine, in moderation, are gradually returned to the diet. You stay with this phase until you will reach target weight.
  3. After, once you’ve reached your goal weight, the diet passes in Phase III, a maintenance phase. In Phase III the diet expands to include three servings of whole grains and three servings of fruit a day. This phase is aimed at keeping your weight steady and the diet recommends you stay on this for life.

This is a diet anyone can love – whether you’re into fast food, home-cooking, or eating at the trendiest new restaurants. The South Beach diet does not require counting calories or limiting servings. The South Beach diet developed so that there are no limits on portion sizes – you simply eat enough to satisfy your appetite.
