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.
For women, the average daily kilocalorie intake increased from 1971--1974 to 1999--2000 and remained relatively stable through 2007--2008. From 1971--1974 to 2007--2008, men consumed more kilocalories on a daily basis than women.
