Are those bars claiming to be "protein bars", or are they claiming to be "energy bars"?
I don't know, there was a big mixture of bars, some of which said "energy" and some that said "high protein". I only bothered looking at the labels of the ones that claimed to be high in protein. If it just said "energy bar" I knew it would be all carbs. I found that even the ones claiming to be high in protein were also high in fat and carbs, except for the one brand of bar.
Edit: Did a search and found a picture of the bars on the web
here. These were the only ones at my local store that were truly high protein low carb. Everything else was high carb.
