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