4. Dukan Diet
This diet is also somewhat similar to the Atkins diet. However, it is more restrictive, especially at the beginning stage because for carbohydrates, only a small amount of oat bran is allowed. Even spinach and cabbage, which are both low in carbs are not allowed.
A lot of critics have questioned its effectiveness. Since it is a complicated diet plan, you should look into it more before you start.
