This is my second time using Prolon. It is so easy to follow and stay on the fasting plan for better health. I lost 6 pounds at the end of five days. I feel great. My bpm dropped 5 points and My anxiety level is nonexistent.

This is my third time trying the fast mimicking diet, and I have learned to go back to it whenever I need a reset. I tend to do great at watching what I eat for a period of time, but then start slipping back into old habits over time. At that point, I find that if I do the fast mimicking diet again, it really does reset my thinking about how much I need to eat.

This was my 10th Prolon fast. I used this one to reset myself due to having long COVID. I can't begin to describe how much better I feel after doing a prolon fast
