Hi L...
I've never used it but my boss and his wife did. They drink the shake but they don't exercise and they both lost a lot of weight (30-40 within several months). They weren't obese or anything...just a little overweight. Anyhow, the only thing is...of course....you have to keep drinking them. I noticed my boss would stop and binge (he travels and have business meals a lot), gain weight, goes back to the shake, loose weight. So...only waste your money IF you're keep it up as they're EXPENSIVE!
