It definitely held off hunger during fasting at the last 30 minutes before the next pouch I was hungry, but decent amount of water which helped with hunger.
For me personally, fasting isn't necessarily easy, but it's simple to follow the plan. A little dedication and discipline and it absolutely works. I have tried it all, and I have found what works - give it a try.
FastBlast has changed me. My gut seemed to be sour most of the time. Not now! 1 scoop a day in water. Bonus- It's an OK taste.
I put it in my Ninja with a banana & yogurt & love it.
