What is BMR?
BMR, or Basal Metabolic Rate, is the number of calories your body needs to maintain basic functions while at rest. These functions include breathing, circulation, cell production, and nutrient processing. BMR represents your baseline energy requirement to survive.
How is BMR calculated?
BMR is calculated using your age, gender, height, and weight. The most commonly used formula is the Mifflin-St Jeor Equation:
For men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5
For women: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) − 161
Why is BMR important?
Knowing your BMR helps you understand how many calories your body burns at rest. It’s essential for planning weight loss, maintenance, or muscle gain. Once you know your BMR, you can adjust your daily calorie intake based on your activity level and fitness goals.
How does BMR differ from TDEE?
BMR is your calorie need at rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities. BMR is a starting point; TDEE adds calories burned through movement, exercise, and daily tasks.
