BMR Calculator

Calculate your Basal Metabolic Rate (BMR) - the number of calories your body burns at rest

Understanding BMR

Basal Metabolic Rate (BMR) represents the minimum amount of energy your body needs to perform basic life-sustaining functions while at rest. These functions include breathing, blood circulation, cell production, and maintaining body temperature.

Factors Affecting BMR

  • Age (BMR decreases with age)
  • Body composition (muscle burns more calories than fat)
  • Gender (men typically have higher BMR than women)
  • Genetics and hormones
  • Environmental temperature

Using BMR for Weight Management

  • Weight loss: Create a caloric deficit below your total daily energy expenditure
  • Weight gain: Consume more calories than your total daily energy expenditure
  • Weight maintenance: Match your calorie intake to your total daily energy expenditure
