Macro Calculator Guide for Fat Loss & Muscle Gain: Optimal Ratios

Counting macronutrients (protein, carbs, and fats) allows you to tailor your nutrition for targeted fitness goals—whether you want to lose body fat, build lean muscle, or maintain weight.

Step 1: Calculate TDEE (Total Daily Energy Expenditure)

Using the Mifflin-St Jeor equation, calculate your Basal Metabolic Rate (BMR) and multiply by your activity factor.

Step 2: Macronutrient Calorie Breakdown

  • Protein (4 kcal/g): Essential for muscle repair and satiety (typically 0.8g to 1.2g per lb of body weight).
  • Carbohydrates (4 kcal/g): Primary energy source for workouts.
  • Fats (9 kcal/g): Vital for hormone production and general health.
