Only fruits and veggies allowed, along with lots of water for three days.

Yes you lose weight, but to the cons outweigh the pros?

According to here are the basics

The Fruit Flush Diet: Basics

The diet is a severe three-day detox session during which you will:Drink at least 12 glasses of bottled or filtered water each dayAvoid non-water beverages, including coffee and teaEat any type of fresh fruits (no frozen, dried, or canned fruits), preferably organicHave salad in the evening ‹ all non-starchy, preferably organic, vegetablesAvoid exercising Consume supplemental protein drinks

The Pros

The main strength of the Fruit Flush diet is that it encourages you to eat fresh fruits and vegetables, which are an essential part of a healthful diet.

“Fruit is one of the healthiest foods in the world,” says dietitian Katherine Tallmadge, RD, national spokesperson for the American Dietetic Association and author of Diet Simple: 192 Mental Tricks, Substitutions, Habits and Inspirations. “The more fruits and vegetables people eat, the healthier they are, and usually the thinner they are.”

The Cons

There is no science to back up doing a detox diet like the Fruit Flush diet and that, rather than doing a one-time detox diet, people should permanently increase the amount of fiber in their diets.

“Having a diet that is high in fiber-rich foods keeps you regular to eliminate potential toxins more quickly and regularly,” Tallmadge said,adding that if you eat a healthful diet rich in fiber, fruits, vegetables, and whole grains, “You will be able to detoxify your system 100 percent of the time.”

Fellow dietitian Elisa Zied, MS, RD, CDN, a spokesperson for the American Dietetic Association and author of Nutrition at Your Fingertips agrees, “Your liver and your body naturally [detoxify you], and there is no evidence that shows that Œdetoxing’ detoxifies you.”

Other pitfalls of the Fruit Flush diet include:

Nutrient deficiencies. Zied does like the fact that the Fruit Flush diet incorporates some protein, which many detox diets fail to do, but she says that the restrictions make it difficult for you to get all of the vitamins, minerals, and other nutrients you body needs.

“This whole plan is not about what you can eat and what you should eat, but what you can’t,” Zied said. “Where is the calcium? Where is the vitamin D? Where are the omega-3 fats? Where are the B vitamins?” Too few calories. According to Zied, you can count on feeling zapped of energy while you are on the diet.

 “If you don’t eat well, you’re not going to feel well,” Zied says.

Temporary weight loss. Zied says that most of the weight you lose while doing the Fruit Flush diet is water weight, along with some lean muscle tissue and some body fat.

“[The Fruit Flush diet] is a temporary solution. You can’t really eat and live this way,” Zied said, adding that you should always be wary of a diet plan that promises such a steep weight loss in just three days.

If you are considering doing the Fruit Flush, keep in mind that it is nothing more than a quick fix, and you will probably regain any weight you lose as soon as you go back to your regular pattern of eating.
