This stuff is awesome! I got the Blue Diamond brand one in chocolate unsweetened and it's only 45 calories for a whole cup. I added some nutrasweet and cinnamon and heated it in the microwave and it was a yummmmy hot chocolate drink!
I wish I could find it somewhere else besides Whole Foods (I think I saw a sweetened one at Trader Joe's, and not sure if it was the same brand, but I don't want to waste the calories on the sweetened!)
I want to get some of the plain or vanilla unsweetened and use it in smoothies/cereal. Yay!
Edited to say: Only problem is I think it doesn't have much protein.
