Yup, hydroxycut will yeild results but it is BAD for your heart. I'd stop taking it if you have family history of heart problems. You're making your heart work a lot harder than it needs to.

Doing enough cardio and excercise will naturally speed up your metabolism. Taking pills alone won't keep your weight off. You have to make a lifestyle change in your diet and excercise. Otherwise you're just slapping a bandaid on the problem.
