Most Weight-Loss Supplements Don't Work
Here's a bummer for anyone hoping hoodia pills (made from a South African plant) will whittle their waistline: A study found that most weight-loss supplements don't work. A researcher reviewed products claiming to block fat or carb absorption, increase metabolism, reduce body fat, or suppress the appetite and found that many supplements had no randomized clinical trials—the best way to determine a drug or supplement's effectiveness—to prove their claims. And those tested showed at most a 4-pound drop in weight compared with people taking placebos. A safer, more effective way to lose weight: Eat fewer calories and exercise more.
