I do not know if it helps lose weight, but do not buy it online. The companies that sell it are scams. I got the free trial and cancelled within the time limit. They messed around with the email I was supposed to get until it was past the limit and said I did not cancel in time. Then they charged me every couple months for things I did not buy. Whenever I called to have them refund me, they lied and never did. I finally had to cancel my credit card. Buy it from the store.
