Question 1

What is BMR?

Accepted Answer

BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions while at rest, such as breathing, circulation, and cell production. It accounts for about 60-75% of your total daily calorie expenditure.

Question 2

What is the Mifflin-St Jeor equation?

Accepted Answer

The Mifflin-St Jeor equation is considered the most accurate BMR formula by the Academy of Nutrition and Dietetics. For men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) + 5. For women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) − 161.

Question 3

How is BMR different from TDEE?

Accepted Answer

BMR is the calories you burn at rest, while TDEE (Total Daily Energy Expenditure) includes BMR plus your activity level. TDEE = BMR × activity multiplier. Your TDEE is always higher than your BMR unless you are completely bedridden.
