If you are looking for a meal replacement bar or simply want to supplement your protein intake, you should take a serious look at VPX's Zero Impact high protein meal bars. I have done my research and sampled many bars out there, but keep coming back to these Pumpkin bars. Why? Well, the flavor is better than most. The can be slightly dry so I suggest having something to drink on hand, but otherwise they are a pleasure to eat and are VERY filling. At 440 calories each, they better be! I usually eat half a bar as a snack or use it as a meal replacement, so the calories are not a big worry. What is great is that they are formulated to have minimal impact on your blood sugar so they actually help curb your hunger and maintain a good level of energy--thus helping you lose weight and maintain lean muscle mass, if that is what you are after. They contain fats, but they are the right fats, and in the proper ratio to protein for optimal assimilation by the body. The Pumpkin flavor actually has the healthiest combination of ingredients of all the Zero Impact bars and in my opinion, the best flavor.
I am currently taking part in a "Biggest Loser" competition at my workplace. I've started exercising more and modified my diet, making these Pumpkin Bars an integral part of it. We've just completed the third week and I'm currently in the lead with just over 12 pounds lost, almost 6% of my total body weight. I wouldn't say I am (or was) overweight, but I could stand to drop some belly and love handle fat. Obviously all of this loss is not due to the Zero Impact bars, but I'm certain they are helping. For anyone looking to lose weight or gain lean muscle, you have nothing to lose by incorporating these into your diet. Buy a box and the per-bar breakdown is just over two dollars. That's really not bad if you think of what you would pay for a healthy meal. Of all the Protein Bars on the market (Clif, Pure Protein, PowerBar, Met-Rx) this is the only one I would give a solid +5 rating.
While the flavor and texture is good, these bars are a bit dry and can be tough to swallow if you bite off too much. Have some water or another drink handy do wash it down--which also helps make it even more filling.
