📘 What is BMR?

Your Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions—like breathing, circulation, and cell production—while at complete rest. It doesn’t include any physical activity or movement.

Understanding your BMR helps you:

  • Plan effective diets
  • Set realistic fitness goals
  • Avoid under- or overeating
  • Track your progress more accurately

📊 BMR vs TDEE – What’s the difference?

BMR only accounts for your body’s calorie needs at rest.

TDEE (Total Daily Energy Expenditure) includes all the calories you burn in a day through activity, work, exercise, and daily life.

👉 Use your BMR as a starting point, then factor in your activity level to get your TDEE for better calorie planning.
