Revolyn Keto BurnThe South Beach Diet: One of the most successful diets in the world, the South Beach Diet does not try to eliminate fat or carbohydrates from your diet. Instead, it tries to limit the amount of fat and carbohydrates that you're going to take in your food. Working on the glycemic index the diet restricts your carbohydrate intake for the initial two week period and then re-introduces those carbohydrates with a low glycemic index. A person following the South Beach Diet should eat three healthy meals daily along with some healthy snacks.
