One of the biggest mistakes when people try lose weight is that they do not consume enough protein. An important thing to remember is that protein feeds, repairs, maintains and helps build muscle. If you're trying to burn fat and lose weight, muscle is going to help this process by speeding up your metabolism. Muscle burn calories 24 hours a day 7 days a week. It's estimated that one pound of muscle tissue will burn 6-10 calories per day as opposed to one pound of fat which only burns 2 calories a day. So feeding, maintaining, and helping repair muscle tissue by consuming enough protein is extremely important in losing fat.
