So I didn't buy this peanut butter because I'm doing any sort of Keto diet. To be honest, I was a little scared to try after buying it. I bought it at Costco (and a few other kinds/flavors) because I love peanut butter and I wanted to explore new brands and flavors. WELL …. I opened the NuttZo jar last night. It hasn't been more than 24 hours and I have shoveled 1/3 of the jar into my mouth! It is so yummy!!!!!! The company has a number of other flavors that I will definitely be checking out!
