Over-the-counter weight-loss products tempt consumers with sometimes outrageous claims that promise to take off pounds easily and effectively. Instead of relying on products, the best way to lose weight and keep it off is to follow a calorie-controlled diet and increase your level of physical activity. If you do decide to use a supplement, consult your doctor first because interactions and side effects can occur.
Alli
Alli, the over-the-counter version of the weight-loss drug orlistat, is approved by the Food and Drug Administration for weight loss. Alli blocks a small percentage of fat from being absorbed into the large intestine. The fat is instead passed during bowel movements. You can lose an extra 3 to 5 pounds per year on average taking Alli, compared with diet and exercise alone. You must follow a low-fat diet while taking Alli because eating fatty foods can increase your chances of developing unwanted side effects, such as gas and loose stools.
Conjugated Linoleic Acid
Conjugated linoleic acid is a supplement ingredient that may help you achieve your weight-loss goals. According to a 2004 study printed in the "American Journal of Clinical Nutrition," Scandinavian Clinical Research scientists found that supplementation with conjugated linoleic acid decreased body fat mass in overweight subjects. The body fat mass for the test group was an average of 6.9 to 8.7 percent lower than the control group after a year. The supplement is sold over-the-counter in soft gel form and manufactured by companies such as Now Foods, Nature Made and ProLab.
Considerations
According to the Mayo Clinic, chitosan, chromium, hoodia, green tea extract and bitter orange cannot be considered effective because insufficient evidence is available to support the products' weight-loss claims.
Warning
Keep in mind that even though a weight-loss product is effective, it does not mean it is safe. For instance, ephedra was a common ingredient in weight-loss products that helped decrease a person's appetite and increase energy levels. However, in 2004 the Food and Drug Administration banned ephedra because of an increased risk of stroke, heart attack and irregular heart beats. Read all warnings before taking a product to lose weight.
