Calculate your Basal Metabolic Rate using the revised Harris-Benedict equation, an alternative method for estimating daily calorie needs.

Frequently Asked Questions

What is the difference between Harris-Benedict and Mifflin-St Jeor equations?

The Harris-Benedict equation was developed in 1919 and revised in 1984. The Mifflin-St Jeor equation (1990) is generally considered more accurate for modern populations, but Harris-Benedict may work better for certain individuals or populations.

Which BMR formula should I use?

The Mifflin-St Jeor equation is recommended for most people as it tends to be more accurate. However, if you have a known body fat percentage, the Cunningham equation may be more precise for lean individuals.

Why do different BMR formulas give different results?

Each formula was developed using different populations and methodologies. The differences usually range from 5-10%, which is why it's important to use BMR as a starting point and adjust based on real-world results.
