Keeps me honest!

I like that this is the STOP signal for my eating. It definitely keeps me full well into the next day.

They are good, if expensive.

I have used this as meal replacements in an effort to lose weight. Last night was the chocolate brownie bar, and it was delicious. Yes, it is not the same as a bakery brownie, but it was chocolatey and rich. I drank a hot tea with it as it was a teensy bit dry and had a satisfying dinner. Great product and I will have to buy more.

Bars

They weren’t too bad, but thought they were dry, and too dense
