About BMR Calculator

Basal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain essential functions like breathing, circulation, cell production, and nutrient processing.

What BMR Includes:

  • Basic body functions (breathing, circulation)
  • Cell production and repair
  • Nutrient processing and protein synthesis
  • Hormone production and regulation

Activity Level Multipliers:

  • Sedentary (1.2x): Little or no exercise, desk job
  • Lightly Active (1.375x): Light exercise 1-3 days/week
  • Moderately Active (1.55x): Moderate exercise 3-5 days/week
  • Very Active (1.725x): Hard exercise 6-7 days/week
  • Extra Active (1.9x): Very hard exercise, physical job

Note:

BMR calculations are estimates. Factors like muscle mass, genetics, hormones, and medical conditions can affect your actual metabolic rate. For personalized nutrition advice, consult with a healthcare professional.
