Muscle Milk says, "these delicious treats (Muscle Milk Light Bars) are ideal when you want a nutritious, convenient snack to tide you over between meals. They are also the perfect calorie control snack for weight management programs." Well, I'm more about the protein, and Muscle Milk has a ton of high-protein products, so when I saw the Muscle Milk Light Vanilla Toffee Crunch Bar, I decided to try it out.
