Great tasting Proton Fasting Bars!!!
I absolutely love the Proton Fasting Bars! I really like the Variety pack because all the flavors are tasty. They are not hard but chewy. I enjoy having one first thing in the morning. It gives me enough to put in my stomach to take my medication without breaking my fast. The sugar content is low and so are the calories. I think they are extremely expensive. I would like to buy more often but they are too pricey.

Good tasting. My go to in the morning to extend my fast.
These are great tasting bars first and foremost. I bought the variety to try, because I really the bars that come in the reset fasting kits, which I do 1-2x per week. These bars are a bit different, but great tasting as well. I ended up re-ordering the chocolate chip and the coconut macadamia in full boxes. I eat these bars in the morning, and they keep me full for an extended period. I don't like doing water fasts. They make me feel terrible to be honest. Fast mimicking is easy for me, and I love it. I usually cut myself off food by 8pm. I will drink water and herbal tea. Upon waking in the morning, I drink black coffee and water. I have one of these around 9AM and I am good until lunch at 12PM. For lunch and dinner, I stick to a reduced carb diet most of the time, but I allow myself anything I want 1 to 2x per week. I am losing weight, have energy, and I am never bloated anymore. Worth a try if you want to lose some unwanted weight and feel better.

Game-changer!
The ProLon Intermittent Fasting Bars are a total game-changer for me. You know how it is when you're doing the whole intermittent fasting thing and suddenly, out of nowhere, you're hit with those snacky feelings or hunger pangs? Yeah, been there. But this variety pack is like a secret weapon. It's perfect for managing those cravings and giving in to your sweet tooth without messing up your fast. Pretty amazing! Only giving it 4 stars because I think the taste could be improved just a little. Otherwise, it's great!

Great flavor
I can’t decide which flavor I like more, they are all so delicious!! Yes, this is a real review and I spent a lot of time reading ingredients and different brands. I’ve tried a few but they were either too dry or the flavor was awful. There are moist and are filling. I start my mornings with one.

Watch for nut shells!!!!
I really loved these bars until I bit into the shell of a nut and cracked a tooth! $5,000.00 in dental work later, I’m terrified to eat them, no thank you!

Snack bars I'll actually eat!
I was pleasantly surprised by how tasty these bars are. If you know me, I have a history of stocking up on healthy protein or snack bars, never eating them, then letting them breeze by their expiration dates and having to throw them out. I haven't been able (or willing) to get on the intermittent fasting train but I've always been intrigued by the concept (except for the part where I have to go hours without food, which is the WHOLE concept). I still don't know how much I buy into the idea but what I will say is that I love these bars. I find myself reaching for them for a hearty and satisfying burst of energy, clean ingredients, and satiety. Out of the variety pack, I love them all but in this order: Coconut Macadamia, Nuts + Honey, Chocolate Chip. I throw them in my bag as a pre or post workout snack or for my breakfast. I will say I don't follow the recommended 15-hour fasting rules but honestly I will keep buying these regardless.

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!
