    Second Cycle

    This is my second round with the Fasting Mimicking Diet. The first cycle seemed easier to tolerate than the second cycle, but in both cycles, I was able to drop 12 pounds. My hope is that with this type of weight management, I won't regain the weight plus. So far, I am very happy with the results.

    4th time. Feel great

    This was my forth time doing the 5 day program. All but the Kale crackers were easy to eat. I lost about five pounds and have more energy than I did before.
