Pure Protein bar??

 Why not just eat some meat for a snack..Then you do not have to worry about the carbs in the forms of sugars and dumping.  Just take small bites and take your time.

I do eat meat, and I don't have problems eating it.  I actually ate a slice of turkey and cheese this morning for a total of 16g of protein 130cals, 6g fat, 3g carbs (2g sugars).  I definitely prefer that over a protein bar, but they aren't nearly as portable.  I like to be able to have protein bars in the car in case I am really hungry and can't find something suitable to eat on the road (and of course in case of car failure on an abandoned road or natural disaster that leaves me stranded. LOL)
