Worked out from 21 CFR 101.9(c)(1)(i) - caloric values of 4, 4 and 9 kcal per gram for protein, carbohydrate and fat and 4 other sources.
Macronutrient targets are general nutrition arithmetic, not medical or dietetic advice. Anyone who is pregnant, under 18, managing diabetes, kidney disease, an eating disorder or any other condition should have targets set by a registered dietitian or physician.

How this is worked out

7 steps
  1. Calorie target = 2000 + 0 = 2000 kcal.
  2. Percentage split 20 / 50 / 30.
  3. Protein 100 g x 4 = 400 kcal.
  4. Carbohydrate 250 g x 4 = 1000 kcal.
  5. Fat 66.7 g x 9 = 600 kcal.
  6. Shares of energy: 20% protein, 50% carbohydrate, 30% fat.
  7. Across 3 meals: 33.3 g protein, 83.3 g carbohydrate, 22.2 g fat per meal.
