Calculate Macronutrient Targets: Multiply Ratios by Total Calories
Once you have determined your macronutrient ratios, you can calculate your specific macronutrient targets by multiplying these ratios by your total calorie needs.
-
Calculate Carbohydrate Target:
Carbohydrate Target (in grams) = Total Calories x Carbohydrate Ratio
-
Calculate Protein Target:
Protein Target (in grams) = Total Calories x Protein Ratio
-
Calculate Fat Target:
Fat Target (in grams) = Total Calories x Fat Ratio
-
Convert to Grams:
To convert macronutrient targets from grams to calories, use the following conversion factors: 1 gram of carbohydrates = 4 calories, 1 gram of protein = 4 calories, and 1 gram of fat = 9 calories.
For example, if your total calorie needs are 2,000 calories and your macronutrient ratios are 40% carbohydrates, 30% protein, and 30% fats, your macronutrient targets would be:
- Carbohydrate Target: 2,000 calories x 0.40 = 800 calories (200 grams of carbohydrates)
- Protein Target: 2,000 calories x 0.30 = 600 calories (150 grams of protein)
- Fat Target: 2,000 calories x 0.30 = 600 calories (67 grams of fat)
