Estimate your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation. Enter your gender, age, height, and weight to determine your daily basal calorie expenditure.
⏳
Formula
Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161Example
Calculating BMR
Find the BMR for a 30-year-old man who is 175cm tall and weighs 70kg.
- Use the Mifflin-St Jeor formula for men: (10 × 70) + (6.25 × 175) - (5 × 30) + 5
- Calculate: 700 + 1093.75 - 150 + 5
- Result: 1,648.75 kcal/day.
