It is a cellular cleanse not a colon cleanse so you don't run to the restroom. It cleans the toxins out of your body which keeps all the cravings away and junk food tastes awful!! It builds lean muscle mass which in turn burns the fat. I do it one day a week and it gives me a lot of energy too. My skin, hair and nails have never been healthier either. You can go to my website www.getoffthescale.com too for more information.
