The Weight-Loss Breakthrough Edge I Needed . . .

Gained a bunch of weight on the lockdown.  Haven't been able to make much progress since October.  So about a month ago I started the 16-8 (and sometimes 14-10) along with a workout program.  I don't do it perfectly every day, but with the help of Fastful, I've lost 8.5 lbs without having that starving, sinking feeling.  It really helps before exercising because it gives me that little boost of slow-burning nutritional calories I need to get through my workout, and the 20g of protein helps me recover.  Tastes a lot better than other bars I've tried, which takes the edge off my sweet tooth.  So far cookie dough is my favorite. Hey, I confess, I wasn't a "diet bar" guy . . but Fastful's a different deal, and for me, a game-changer.

I am thrilled that I found this protein bar. I am beginning my intermittent fasting journey and these bars are perfect for my sweet tooth cravings. The texture is perfect, chewy but not chalky! I cannot wait to try it in the microwave next. Definitely recommend 10/10.
