What percentage of the calories consumed in a day should be from fat, protein and carbs?


The Dietary Guidelines for Americans recommends this distribution for the energy nutrients:

  • Fat: 20 - 35% of total calories (average 30%)
  • Protein: 10 – 35% (average 15%)
  • Carbohydrates: 45 – 65% (average 55%)

Some healthy diets, like the Mediterranean Diet, promote 40% of calories from fat, but the fat must be olive oil, fish oil and nuts.  Alcohol is the fourth energy-producing nutrient, and it is recommended in moderation, if at all.
