Healthy lifestyle go long way rather than having such a supplements.
These supplements are not recommendable. No qualified dietitian or doctor precribe these suppliments. Some ill effects on health have been noted with this supplement like rash ,
liver damage etc.
Eating normal well balanced diet gives us satisfaction, satiety. It could not be replaced by such a suppliments on daily basis.
Weight loss will happen till you are using these suppliments. But the moment you stop taking these supplements , and you are not eating right, or you have not modified your lifestyle you are going to increase your weight which is undesirable.
So to my opinion once you realize you need to change, working on right food, healthy lifestyle is right choice than any shortcuts. And one should not hesitate to take professional help in this regard. Your doctor or dietitian can suggests right suppliment for you after understanding the details.
