Good taste and apparently don’t break a fast

I eat these because they don't give me cravings afterwards
I tried the Prolon 3-day fast but I didn't like it much but I liked these protein bars. Handy for when you don't have time to eat...you just need something and this is the healthiest option. Slightly sweet..very slight which is what I love about them.

Best intermittent fasting bars ever!
These bars are expensive, but worth it! They are very satisfying, taste too good to be true, and the texture is smooth. In a nutshell they are beyond amazing. 🤩 Just one bad gives sustained energy on fasting days. With a low sugar content they work for those who fast. They are extremely filling, too!

Even tastier with good coffee
These are tasty. And they pair extremely well with coffee! Will have to report back on weight loss effectiveness…

Delicious, Trustworthy, and Convenient Fasting Bars
I tried the variety pack and have really enjoyed all three flavors: Nuts & Honey, Chocolate Chip and Coconut Macadamia Nut (my favorite). These bars are such an easy and convenient way to extend my intermittent fasting, while still getting healthy ingredients into my diet. I love that Prolon has really invested in trustworthy research of the benefits of the fasting-mimicking diet and intermittent fasting, to develop top-quality products that I trust are good for me. These bars are super tasty and satisfying and a great way to start the day without a lot of fillers and unknown ingredients you find in some bars. I’ve never seen any other bars that can be incorporated into a fasting regimen either. Will definitely purchase again.
