According to the Average Macronutrient Distribution Range (AMDR) 10-35 percent of the average adultâs daily kilocalorie intake should come from protein, which is approximately 50-175 grams per day. The average intake in the United States falls in between that range at about 80 grams per day.
The body can burn carbs and protein for the same yield of 4 calories per gram. Nutrients are chemicals that your body requires for growth, development, metabolism and proper function. Carbohydrates, fats and proteins belong to the macronutrient category because your body needs them in large quantities. Carbohydrates directly supply glucose, your body's preferred fuel source. While proteins have other primary roles, they can also supply energy whenever carbohydrates are not available.
