If the 'magic bullet' approach worked, we wouldn't be a nation of obese people! It's another gimmick designed to prey on people's hope and desperation for weight loss. Don't waste your money.
Instead, continue your working out AND make sure you are following a sensible nutritional plan (one that you can adopt for the rest of your life). Take the money you might spend on a gimmicky product and go see a nutritionist instead.
Maintaining a healthy weight isn't about exercising and dieting for a short period of time until you achieve your goal; it is something you will do for the rest of your life. Good luck to you and hopefully you'll reach your goals!
