My mom was taking Metabolife, and strted to get really sick, she went to the doctor, found out that she had heart damage due to the Metabolife, and a very low potassium due to the Metabolife. Low potassium damages your heart as well, so she got a double dose of heart damage. I wouldn't advise anyone to take metabolife, it might make you sick, or worse!

I was looking for a way to kick start my diet a few months ago and found myself wondering if one of these supplements might do the trick. So, I asked my doctor about it and, while she didn't seem too critical of them, she still advised against it. This was mainly because these types of diet aids tend to boost your metabolism by speeding up your heart rate. If you tend to have high blood pressure this could be a very bad thing. Your best bet for getting your metabolism back in working order is to start off with some moderate exercise. It's the natural way to do it and it works.
