How to read the Macro Calculator result
A macro calculator splits daily calories into protein, carbohydrate and fat grams so the target is easier to plan as food.
Specific formula
- Protein grams = protein calories ÷ 4
- Carbohydrate grams = carb calories ÷ 4
- Fat grams = fat calories ÷ 9
Example interpretation
Example: at 2,200 kcal with 30% protein, 40% carbs and 30% fat, the target is about 165 g protein, 220 g carbs and 73 g fat.
Common mistakes
- Setting percentages that do not add up to 100%.
- Using macro targets without checking total calories.
- Treating one day of imperfect tracking as failure instead of looking at weekly consistency.
Macro targets are planning numbers. Individual nutrition needs vary.
