AKirkland..
Hi there-
I don't know your first name, so hopefully you will read this.. Have you tried the Detour Bars by Next Proteins? Those don't seem to wreak the havoc on the system that most of the other ones do. About 300 calories for 30 gms of protein and they actually taste pretty good!
As far as shakes, Isopure does a pretty good one and its sweetening is done Ace K and Sucralose (splenda). The chocolate and chocolate peanut butter are the best!
I agree with you about Balance Bars.. I don't have much of a problem with those either! Can you eat Zone bars? They are pretty good, too. But I think they have some soy in them, which can also be problematic for some people's digestive tracts.
Getting enough protein in for me is a challenge too.. I am not a big meat eater, so the bars/shakes are pretty key for me as well..
Take care, Lynn
