The manufacturer of the 15-Day Weight-Loss Cleanse and Flush supplements claims that after 15 days of using its product, you'll be healthier and more energetic and have a cleansed digestive tract that will make it easier for you to lose weight and get a flatter abdomen. But New York University Langone Medical Center cautions that the 15-Day Diet supplements and others like them are based on faulty science and may cause harm.
The 15-Day Diet doesn't include any changes to your regular eating habits or require you to begin an exercise program. Dieters are simply instructed to consume two weight-loss capsules twice each day along with at least one glass of water. Drink an additional eight to 10 glasses of water daily. Taking the supplements will supposedly cause your body to begin metabolizing fat at a higher rate. Once you've completed all 15 days of the plan, stop taking the capsules and don't attempt to repeat the cycle for at least 30 days.
Each two-capsule serving of the 15-Day Diet supplements contains ingredients with natural laxative properties, including psyllium, uva ursi extract, juniper berry powder and cascara sagrada bark powder. Chlorella, a type of green freshwater algae, is included in the dried, powdered form as a source of vitamins and minerals. Other ingredients include calcium carbonate; powdered fennel seed, cayenne pepper, beet, oat bran, dandelion root, Echinacea, chickweed, prune and grapefruit; and extracts of chamomile, ginger, marshmallow and black pepper. Inactive ingredients such as silicon dioxide, microcrystalline cellulose and vegetable magnesium stearate are used to bind the other ingredients together and prevent clumping.
Dieters who lose weight taking the 15-Day Weight-Loss Cleanse and Flush supplements might feel encouraged enough by their success to make the lifestyle changes needed for long-term, sustainable weight management. This isn't certain, however, and there aren't any clinical studies proving this program is any more effective at promoting weight loss than other methods. Some of the supplement's ingredients, including oat bran and the powdered fruits, have been linked to weight loss because of their high fiber content, but most haven't been researched enough to know if they are capable of doing what the manufacturer states.
NYU Langone Medical Center contends it is not true that intestinal cleansing is needed for weight loss or that waste and toxins build up in your digestive tract at all. As a dietary supplement, the 15-Day Diet capsules aren't regulated by the Food and Drug Administration for purity or safety, and the manufacturer is not required to prove with scientific research that the product functions as advertised. Some of the ingredients, including psyllium, uva ursi and cascara sagrada, can cause potentially harmful side effects such as dehydration and liver damage, or they may interfere with the function of prescription medications. Do not start the 15-Day Diet if you're pregnant, nursing or planning to become pregnant or if you suffer from digestive disorders or a chronic disease.
