As a teenager, how should I lose weight around my thighs, hips, and mid-section?

Ok keep in mind that I have been an opponent of Diet programs and I do not make it a habit of promoting them. My Wife started the HCG Diet, without my approval and lost 20 pounds in 20 days. It's has been over 5 months and she has kept off all the weight off the diet. It works, it actually reprograms your metabolism and burns only fat. The trick is that you have to follow the diet to the T. But if you do, It freakin works. Also my 300 pound step father has lost 60 pounds in about 70 days and when I visited him last week, I almost cried. My mother lost about 25 in about 50 days, but she cheated on the program and it cost her less weight loss. You don't do exercise until after you are off the diet, and the results are crazy. Google it HCG Diet, I think they have it in the grocery store, but make sure you read the book and follow all the rules.
