Based on years of research that examined the relationship between nutrient intake and disease prevention, generally-accepted ranges have been established for carbohydrates, fat and protein intake. These healthy ranges also help to ensure that a person is getting a sufficient intake of other essential nutrients, vitamins, and minerals. The recommendations are:
45% to 65% of calories eaten should come from carbohydrates.
20% to 35% of calories eaten should come from fat.
10% to 35% of calories eaten should come from protein
The table in this article converts these percentages into grams needed each day based on calorie intake. Finding the right ratio of macronutrients for your body type, activity level and goals is a process that many fine tune as they go along.
