Carlos will have to consume about 63 gram of protein per day. The dietary reference intake of protein is 0.8 gram of protein per kilogram body weight or 0.36 gram per pound. Carlos is 175 pounds in weight, so he is going to need 0.36 * 175 = 63. Thus, Carlos needs 63 grams of protein per day.<span />
