As far as I am concerned, it should only be used coupled with lifestyle and diet changes. Drop 5lbs with it and use the next few months to make further changes with your lifestyle and diet and then use it again for another 5 lbs.
Lifestyle changes alone can do that.
Nobody needs drugs to *help*.
I know someone who has lost over 50 pounds and counting just by eliminating junk food; soda, snacks like chips, and fast food.
