Get the benefits of fasting without getting exhausted...

Get the benefits of fasting without getting exhausted and burning off all the muscle. I resumed heavy weight lifting right after the fast. This really is a breakthrough.

I can’t recommend ProLon enough...

I discovered ProLon last January and I have been doing it consistently ever since then. It is a really great reset for your body, especially after holidays. It has so many different benefits, it curbs sugar cravings and helps me manage portion control.

I'm 50 years old with 2 small children...

I started ProLon and I'm telling you, it worked! I lost 6 pounds, I have no brain fog, I absolutely do not crave sugar right now which is insane and I actually feel amazing, I'm full of energy! I am so proud of myself, my husband did it with me, he lost 5 pounds, says he has never felt better.

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.
