How This Calculator Works
Calorie Calculation
Uses the Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR), then adjusts for your activity level to determine your Total Daily Energy Expenditure (TDEE).
Macronutrient Distribution
Protein is calculated based on your body weight (2.2g per kg), fat is set at 25% of total calories, and carbohydrates make up the remaining calories.
