You have seen them on supermarket shelves: Skinny Water, Fuze Healthy Infusions Slenderize, Enviga. These beverages claim to help curb your appetite, boost your metabolism, and burn fat. "Wow, this is such a great deal!" you may think to yourself. "Not only do I get to drink something that tastes good, I also get to burn fat, and lose weight!" Not so fast.
The key ingredient in many of these beverages is green tea extract or caffeine. Short-term studies have shown that these additions can give your metabolism a small boost (about 3.5% average), and burn an average of 78 calories.
But in a 2006 issue of Obesity Reviews, researchers noted that additional studies were needed to determine whether the products actually help you lose in the real world, over the long haul. Some products included ingredients that you find in over-the-counter weight loss supplements (ex: Citrus aurantium, chromium picolinate).
Bottom line: Do not expect to lose weight just by drinking these beverages. The best way to lose weight is to combine exercise with a healthy diet, not by drinking "Skinny Water" and hoping the pounds will come off.
