What Protein Does in Your Weight Gain Diet

Protein is necessary for metabolic function and other bodily processes and it also helps our immune system to fight off disease. It is a building block in hair, finger nails, skin, cartilage, muscles and bones. Adults need protein to build up and replace tissues that are breaking down with use and children need protein to grow. You can get protein from meat, eggs, beans, grains and dairy products. Although protein helps your metabolism, it should not be avoided in your diet for weight gain. A balanced mix of the food groups will help you maintain a healthy lifestyle while maintaining a healthy weight.
