The FDA has warned several companies selling the diet drug HCG that they better stop their "fraudulent" marketing schemes.
HCG is a hormone produced by pregnant women. Diet drug companies say taking it (either orally or by injection) can help a person lose weight, but the FDA points out that it's the 500 calorie diet you have to stick to that causes the weight loss -- not HCG.
FOX Chicago News medical contributor Dr. Mona Khanna joined us on FOX Chicago News at 9 to explain why the FDA says HCG is so dangerous.
