I love the Horchata and so does my son. He lost most of his 130 lbs on it a couple of years ago. As far as it making a noticeable difference in weight loss..no way to know really since we are already losing rapidly on the regular Cambridge. It has shown in clinical testing to increase lean tissue development and protect what you already have, so if you are trying to protect or build muscle like my 6'6" son was then this may interest you. I sell tons of Tonalin CLA. People really like it.
