How this calculation works
The macro nutrient calculator converts a calorie target and your chosen carbohydrate, protein, and fat split into daily grams. It can help organize meal planning, while leaving the food choices, medical needs, fibre, micronutrients, and cultural preferences for a more complete nutrition plan.
Mathematical formula and logic
Carbohydrate and protein supply 4 calories per gram; fat supplies 9 calories per gram.
Worked example
A 2,000 calorie target with a 45/25/30 split produces individual gram targets for each macro.
Calculation assumptions
- Percentages should add to 100 for a complete split.
- Protein and carbohydrate use 4 kcal per gram.
- Fat uses 9 kcal per gram.
- Use a dietitian for medical or performance-specific targets.
