Hoodia is an appetite suppressant. Diet companies of all sorts are all out to make the almighty buck. Some pills will help you shed some fat, but you want to play it smart and keep the weight off. These pills can be dangerous. Go on the "South Beach Diet" or "Weight Watchers." Both of these are good diets, and actually, Weight Watchers isn't so much a diet as it is teaching people to eat healthy and be the weight their bone structure permits. Drink those 8 - 8 ounce glasses of water a day (flushes out fats and toxins) and exercise.
