Based on your inputs, here's your estimated Basal Metabolic Rate (BMR):

  • Harris-Benedict Equation: calories/day
  • Mifflin-St Jeor Equation: calories/day

Understanding Your Basal Metabolic Rate (BMR)

Your Basal Metabolic Rate represents the number of calories your body burns at rest to maintain basic life functions. Knowing your BMR is crucial for:

  • Setting realistic weight loss or gain goals
  • Designing effective meal plans
  • Optimizing your fitness routine
  • Understanding your body's unique energy needs

Our calculator uses two widely respected equations to estimate your BMR:

  1. Harris-Benedict Equation: A time-tested formula that's been used since 1919.
  2. Mifflin-St Jeor Equation: A more recent equation (1990) that some studies suggest may be more accurate for the current population.

Remember, BMR is just one piece of the puzzle. For a complete picture of your daily calorie needs, consider factors like physical activity level and specific health goals.
