The Promise

Spend 3 days eating fruit, salad, and protein, and you'll cleanse your system, kick food addictions, and lose up to 9 pounds.

Plan developer Jay Robb, a clinical nutritionist, says Fruit Flush gives your digestive system a break from overprocessed foods; lets low-calorie, fiber-rich fruits (and some vegetables) clean your system; and puts your body into fat-burning mode.

Does It Work?

Most of the weight you'd lose would be from water, and you're likely to gain it back when you go off the diet. This plan isn't a long-term solution or lifestyle.

Fruits and vegetables are key parts of a healthy diet, and most Americans don't eat enough of them. There’s no proof, however, that only eating plant foods will help you "detox" or burn fat.

What You Can Eat and What You Can't

The first day of Fruit Flush consists of a protein shake every 2 hours between 8 a.m. and 4 p.m., followed by 8-12 ounces of water. Dinner is a raw salad (no starchy vegetables) with olive or flaxseed oil, or half an avocado, along with 3-6 ounces of lean protein or egg whites.

The next 2 days are all about fruit from 8 a.m. until 4 p.m.: one 100-calorie serving of fruit every 2 hours. Dinner is either salad or half an avocado, plus one protein shake.

If you’ve got a caffeine habit or enjoy a glass of wine with dinner, you’re out of luck. Seasonings, sweeteners, and salt are off this plan.
