Lean body low carb are good in terms of content, not all of them taste that great. In my opinion solid protein bars by natures best are the best thing your gonna find. They have taken all the fillers out of their bars and they have very low sugar/carbs and also taste good.
mesotech mint chocolate by MT tastes awesome. 300 cals though. for under 200 cals i like the zone perfect bars...higher in fat and carbs since they are balanced. only 16 grams of protein and its mostly soy. but for low cal and taste they are good. Lean body are good like GF said, the mint again tastes good. cookies and cream used to taste good....but the latest batches sucked. overall mesotech's taste the best to me...but they have a decent amount of carbs in them. i usually eat either Mesotech or zone perfect myself.
DETOUR by Designer Whey. They taste like Snickers bars. They have not started shipping them yet, but I ate them at the Mr. O and they were fucking awesome.
i seem to like the pure protein bars. Only the strawberry then the blueberry. They are cheap too if you go to a BJ's. Its a store in the nj area. kmart also has them real cheap
