If you have a special occasion coming up, or you simply need to lose weight fast, the Cabbage Soup Diet may be just what you're looking for.
Although not suitable for long-term weight loss, the Cabbage Soup Diet is a low-fat, high-fiber diet that will help you get into shape fast before you embark on a more moderate long-term eating plan.

Pros and Cons of the Cabbage Soup Diet

Pros: You'll lose weight fast, and can get as much of the foods listed in the program as you want. Although the diet is only for seven days (and shouldn't be adhered to for longer), it provides a great "kick-start" for a more moderate diet.

Cons: Some people find the soup bland. Some people have reported feeling light-headed, weak, and have suffered from decreased concentration (although some who have been affected in this way felt it was well worth it, since it was only for a week and they had lost considerable weight).
