Understanding BMR

What is Basal Metabolic Rate and why it matters

Basal Metabolic Rate (BMR) represents the minimum amount of energy your body needs to perform essential functions while at complete rest. These functions include:

  • Breathing and circulation
  • Cell production and regeneration
  • Hormone regulation
  • Brain function
  • Maintaining body temperature

Your BMR accounts for approximately 60-75% of your total daily calorie expenditure, making it the largest component of your energy needs.

Why BMR is important:

  • It helps determine your daily calorie needs
  • It's essential for effective weight management
  • It can help identify metabolic issues
  • It provides a baseline for nutrition planning

Note: This calculator uses the Mifflin-St Jeor Equation, which is considered the most accurate formula for estimating BMR in most individuals. For athletes or those with very high muscle mass, results may be less accurate.
