Frequently Asked Questions
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at rest. It accounts for about 60-70% of your total daily energy expenditure.
How accurate is this BMR calculator?
Our calculator uses the Mifflin-St Jeor Equation, which is considered the most accurate for calculating BMR. However, individual variations may exist due to factors like muscle mass, genetics, and medical conditions. For the most precise measurement, consider professional metabolic testing.
How often should I recalculate my BMR?
You should recalculate your BMR every time your weight changes by more than 5-10 pounds, or every 3-6 months as your body composition changes. Significant changes in activity level, age, or muscle mass also warrant recalculating your BMR.
Note: This calculator uses the Mifflin-St Jeor equation, which is considered the most accurate for calculating BMR. The results are estimates and should not replace professional medical advice. Individual results may vary based on factors such as muscle mass, genetics, and health conditions.
