Mifflin-St Jeor Calculator
The gold standard for BMR calculation - most accurate for general population
How the Mifflin-St Jeor Formula Works
Developed in 1990, this formula is considered the most accurate for calculating Basal Metabolic Rate (BMR) in healthy adults. It's more precise than the Harris-Benedict equation and is widely recommended by nutritionists and fitness professionals.
Men: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age + 5
Women: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age - 161
