Guys: Don't be fooled by the "low-carb" labeling on most protien bars. After reading the ingredients, you will discover the second largest component of any "low-carb" bar is glycerine. Glycerine is made by Dow Chemical, and is a waxy substance used i a variety of household products and some foods. It keeps the bars moist, but is broken down by your body simillar to a carbohydrate, but really is providing empty calories as it is not a macronutrient. The reason the companies don't list glycerine in the carbohydrate count is because the FDA doesn't require them too. This is something that may change in the future, however. I would stick with 100% whey protien powders for supplementation purposes, but if you are in a hurry, the only bar I've found without glycerine or sugar that derives most of it's protien from whey is the Innovation bar, made by a little company called SunValley Labs out of Jersey (I think). 230 cal, 20g protien, 25g carbs, 5g fat. Tastes good too.
