01
What is BMR?
Basal Metabolic Rate (BMR) represents the minimum energy needed to keep your body functioning at rest. This includes breathing, circulation, cell production, and basic neurological functions.
02
Calculation Method
We use the widely used Mifflin-St Jeor equation. It uses weight, height, age, and the sex-specific constant defined by the formula to estimate BMR.
03
Factors Affecting BMR
• Muscle Mass: More muscle = higher BMR • Age: BMR decreases with age • Gender: Men typically have higher BMR • Genetics: Can influence your baseline metabolism • Health Conditions: Various conditions can affect BMR
04
Using Your BMR
BMR helps determine your daily caloric needs. To maintain weight, you'll need to eat more than your BMR to account for daily activities. For weight loss, create a deficit below your total daily energy expenditure.
05
Important Notes
BMR is a baseline estimate, not a calorie prescription. Total daily needs also depend on activity, digestion, health, and individual variation.
06
BMR Formula Explained
Mifflin-St Jeor Formula: Men: (10 × weight) + (6.25 × height) - (5 × age) + 5 Women: (10 × weight) + (6.25 × height) - (5 × age) - 161 Weight in kg, Height in cm, Age in years
Method and sources
Method: Mifflin–St Jeor resting energy equation.
Supported population: Adults age 18 to 100 using the equation's sex-specific constant.
- Weight is stable and measured in kilograms
- The population equation is an appropriate estimate
Frequently asked questions
How is the BMR estimate calculated?
Mifflin–St Jeor resting energy equation.
What are the limitations of this BMR estimate?
BMR is an estimate and is lower than total daily calorie use because it excludes normal activity.
