Prolon FMD is the way!
If you're looking to get a jump start on changing bad eating habits, using the 5 day Prolon kit is the way. I also shed around 5 pounds while doing this. I'm looking forward to doing the 5 day fast quarterly. It can leave you feeling a bit tired and you might have a slight headache while on it but you'll feel fantastic afterwards. Highly recommend.

Best in taste breakfast bar
This is one of the best tasting breakfast bars on the market. All the ingredients come from natural foods with no chemical additives. Would have rated as a 5 however it is fairly pricey.

Expedited delivery?
I went to check out and saw it was going to arrive march 28th, 5 days later, so I added the $10 expedited and it was still March 28th so my excitement for starting early will still have to wait.

I really like the Fasting Mimicking Diet and have found it works and is relatively easy to do. To be honest, everything about this company has impressed my husband and I.

I love working with this company and using their products.

What is terribly frustrating is the different product options-they are not well laid out/explained AND importantly I cannot get answers to the questions I have via your chat system or emails.

Love Prolonlife
Love Prolonlife. I am usually eating horribly. So, I dedicated 1 day a week where I will fast 24 to 36 hours fast. I called it sabbath fast. One day for my body to rest and clean out any bad stuffs in my body. I do the 5 days fast before but with my schedule and my lifestyle, 1 day worked perfectly for me. I might try 5-2 soon.

Hi Kim,
Thank you so much for sharing your experience! It’s wonderful to hear how you’ve created a routine that works for your lifestyle, and I love the idea of your “Sabbath Fast, giving your body a dedicated day to rest and reset is such a mindful approach.
It’s great that you’ve tried the 5-day FMD before and found a rhythm with one day per week; listening to your body and fitting fasting into your schedule is key for long-term success. The 5:2 approach could be a great next step if you want to explore more structured cycles while still maintaining flexibility.
We’re so glad Prolon is supporting your health journey, and thank you for letting us be part of it!
