About BMR

Basal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain basic physiological functions.

This includes breathing, circulation, cell production, brain function, and temperature regulation.

  • BMR accounts for 60-70% of daily calorie burn
  • Age, gender, weight, and height affect BMR
  • Muscle mass increases BMR
  • Mifflin-St Jeor equation is most accurate

Factors Affecting BMR

  • Age: BMR decreases with age
  • Gender: Men typically have higher BMR
  • Weight: Higher weight = higher BMR
  • Height: Taller people have higher BMR
  • Muscle Mass: Muscle burns more calories than fat
  • Genetics: Some people have naturally higher BMR

Boosting Your BMR

  • Build muscle through strength training
  • Eat adequate protein
  • Stay hydrated
  • Get quality sleep
  • Manage stress levels
  • Eat regularly throughout the day
