Manual Macro Diet Method

The Formula of BMR (Basil Metabolic Rate)

For manual calculations you have to use BMR. There are 2 formulas to calculate in


BMR for Men

66.47+ (13.75+ weight [kg] +  (5.003*size[cm]) – (6.755*age [years])

BMR for Women

655.1 + (9.563* weight [kg]) + (1.85*size [cm]) – 4.676 * age [years])

All macros are not created equal. Each macronutrient corresponds to a specific calorie amount per gram. 

Carbohydrates has 4 calories per gram

Proteins supply 4 calories of energy per gram

Fats consist of 9 calories per gram

Each individual is different so every person‘s preferable macronutrients intake will differ. 

Macronutrients Ratio For Weight Loss

  • 10-30% carbohydrates
  • 40-50% Protein
  • 30-40% Fats

First you need to know how many calories you eat one day. Suppose you eat roughly 2300 calories per day. For losing weight, you cut down 500kcal from calories we take per day. 

2300-500=1800kcal per day 

Next, determine your ideal ratio. Then, multiply your total daily calories by your percentage.

Finally divide your calorie amounts by its calorie-per gram number 

Calculate your each macronutrient


Macro Ratio for Weight Loss

  • 30% Carbs
  • 40% Protein 
  • 40% Fats


1800 multiply by 0.3 equal to 450 kcal 


1800 multiply by 0.4 equal to 720kcal 


1800 multiply by equal to 720 kcal 

To Calculate Gram Amount 

Carbohydrates(4 calories per gram) 

450 divide by 4 equals to 112, 5 grams of carbs 

Protein (4 calories per gram) 

720 divided by 4 equals 180 gm of protein

Fat (9 calories per gram) 

720 divided by 9 equals 80 grams of fats

In this way, you get your new macros with percentages to track your weight. That is rather hectic task.
