In the fitness industry, questions regarding protein and carbohydrates come up a lot. The body needs both protein and carbohydrates to grown, maintain, repair itself and increase lean body mass. Protein is needed to build and repair body tissues and structures. The recommendation for a strength athlete would be to consume 0.5 to 0.8 grams of protein per pound. Protein intake should be spread throughout the day and not taken all at once. Too much protein can be stored as body fat. Carbohydrates are the main source of energy used for your body and muscles while working out and they also help regulate digestion and the use of protein. The recommendation for carbohydrates would be 2.7 to 4.5 grams of carbohydrates per pound. Consuming protein and carbohydrates within 90 minutes after a workout will increase recovery that is needed for your body. Remember, excess amounts of protein and/or carbohydrates over daily calorie needs can cause weight gain.
