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.

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.

I have always said there is no way I… I have always said there is no way I could do more than a 24 hour fast, let alone the number of days it takes for change in one’s body. Yet your Five day mimic Fasting made doable,the impossible,and even allowed me to move into an Elimination diet to see what may be cause of problems in my health journey.

I wasted 200 GBP, had to throw the whole thing away. Part of the package contained food that expired on an extremely short notice. They promised a replacement 5 times via email but never delivered it. Eventually they blocked my email address. If they are this trustworthy (keeping promises) and care about customers or customer experience this much, imagine how many of the claims about the product might be true. Reminds me of the old saying goes, "if it sounds to good to be true...then it's a scam." Avoid.

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.
