Who could have predicted that we would spend billions of dollars each year on diet pills? Yes, billions. These tiny little capsules, powders, juices and patches, that we are so certain provide the absolute cure for a thin, slender body, rake in substantial amounts of money each year and have very little regulation. They are as varied as diets on the market and provide everything from fat burning and weight loss, to increased energy, sex drive, more youthful skin, metabolism boosters and appetite suppression.
