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 lost £398 I paid £398 for two boxes that were never delivered. Prolon says they were delivered to a neighbour, but the neighbours say they hadn't accepted any delivery. Also, I had not given permission to deliver anywhere other than me, personally. I asked Prolon to investigate, but they never replied.

I’ve done 6 five day fasts and they… I’ve done 6 five day fasts and they work fine but boy does one fatigue with the included food options! 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!

Promised discount code never delivered You promised me a $40 discount while I was at the summit, but although I have been in constant contact with Sarah via texting, she will not give me the coupon code. This has been quite frustrating and discouraged me from trusting your company.

Worst experience Worst experience - the soups are inedible, they have a gooey texture and the powder doesn't dissolve well. The L-bars are disgusting and inedible as well. Biggest waste of money. Not surprised people lose weight - this makes you starve for 5 days straight since the things they give you are inedible. The only thing that is somewhat good are the olives. Do not waste your money on this. And to add to that I paid $10 for express shipping and it took way longer than 3 days to get to my house.
