percentage of total calories from protein
Daily Protein Intake. As long as your kidneys are healthy, about 15 - 20 percent of your daily calories should come from protein, which is the same amount suggested for a regular balanced diet. About 45 to 50 percent of your caloric intake should come from carbohydrates, and the rest should come from fat. A person who needs 2,000 calories per day needs about 75 to 100 grams protein per day.
