Hi, I have used the MCT oil for 2 months so far I am unsure if I have lost weight but I do know that I have lost fat in the form of inches around my waist and in the area that my wife used to call love handles, which no longer are to be found. I have during this time gone from a size 36 to a size 33, while keeping my muscle. I am Impressed, and will continue to use this product!
