Query: Best tasting protein bars

These are the best tasting protein bars i've ever eaten. the taste sweet but only have 5 grams of sugar. they don't have that bad chemically tasting sweetness that alot of low sugar foods have. they only have 200 calories whereas most of the protein bars i've tried have over 300 calories. i've been trying to lose weight and starting eat one of these bars a day to try and keep myself from eating candy bars. they definitly satisfy my craving for sweets. i've lost 4 lbs in the past few weeks so at least i know they aren't preventing me from losing weight like my daily candy bar fix was. also the carb amount is fairly low in these bars. i'm hooked on them and will plan to keep buying them in bulk.
