I was hesitant at first to try these cookies because I have tried diet shakes and have a problem with whey protein that is in most of those products. The cookies turned out to be a very nice surprise, they don't hurt my stomach, they taste nice, although I bought the four varieties and 3 of them apart from the chocolate ones all seem to taste the same. I believe a ginger one would be nice if you consider that in the future. The diet is easy, there is no effort, within a couple of days I have learned not to be hungry in between and I am drinking much more water now which is beneficial.
