Those bars are hard to tolerate frankly and I only could eat one this past cycle on the first day! I supplemented the soups each day with veggies to somewhat compensate for those lost calories and nutrition!

Very happy with this comprehensive… Very happy with this comprehensive fast. I returned to buy some of their products after completing. I would purchase again and highly recommend to individuals that want to fast but not miss out on important nutrients.

The little bit of food is a game changer. 3 days of water fasting is difficult, 5 days is almost impossible for me. However having the little bit of food to eat on the Prolon fast is a game changer. I love the couple of times on days 3 and 4 that a sudden feeling and movement in my intestines was so noticeable. I'm sure that is proof that so much healing was happening there. I know that I need to repeat this 5 day Proton fast again the next two months in order to address more health issues. I'm thankful that I don't have to do this alone and with water only.

My son introduced me to the 5-day… My son introduced me to the 5-day mimicking fasting protocol, and as a cancer survivor I thought I might give it a try. Though I have been nearly 20 years recovered (some say 'cured'), it seemed an interesting step to take. Weight loss isn't an issue––I lost 4.5 lbs in the five days, and I'm sure that most, if not all, of that will come back in the coming weeks as I return to my regular diet. Day 2 was probably the hardest, feeling hungry every minute. Now, on the first post-fast day, I'm feeling great, easing back to my regular routine (mostly plant-based diet, along with fish, and small amounts of other animal proteins). I will very likely try the fast again in 4 months, and then 4 months after that––three times for the year.

I appreciate the science behind the… I appreciate the science behind the program, that's one of the things that kept me going. I struggled a bit with hunger, but not enough to give up. I did feel better when the Fast was over. I am doing the program to address metabolic issues and I intend to continue with two additional fasts to see if this program helps in anyway. The food was also very good and that made a big difference for me as well.
