How The Diet Works?
The South Beach Diet follows the same principles of other diets based on the Glycaemic Index. Plus it recommends swapping saturates for unsaturates. When we've eaten, the carbohydrates in food get broken down into sugars, which are then absorbed into the blood causing a rise in blood sugar. In response, the hormone insulin is released from the pancreas to remove the sugar from the blood.
Dr Agatston claims that the diet he created is not low-carb or low-fat diet - instead it focuses on eating the 'right' carbs and the 'right' fats. In fact, the South Beach Diet is based on the Glycaemic Index. In practice, the diet severely restricts carbohydrates in the first two weeks, before gradually re-introducing those with a low glycaemic index. Plus it recommends swapping saturates for unsaturates.
