The advant edge carb control shakes and bars are pretty good, i mean they aren't like candy bars and steak and shake shakes, but they are some of the better tasting stuff out there. They are by EAS. If you limit ur carb intake, and add a little more protein, and also do some form of a work out, you can lose a fair amount of weight. Even if you didn't use the advant edge stuff, and lowered ur carbs and boosted ur protein, u would lose a considerble amout of weight. But that is just my in put. O also another good thing to do is drink half of one, work out, then drink the rest. (refidgerate for best taste)
