Question 1

What is BMR (Basal Metabolic Rate)?

Accepted Answer

BMR is the number of calories your body burns at rest to maintain vital functions like breathing, circulation, and cell production. It represents the minimum energy needed to keep your body functioning while at complete rest.

Question 2

How is BMR calculated?

Accepted Answer

BMR is calculated using the Mifflin-St Jeor equation, which considers your weight, height, age, and gender. For men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5. For women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161.

Question 3

What is the difference between BMR and TDEE?

Accepted Answer

BMR is the calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through daily activities and exercise. TDEE = BMR × Activity Factor.

Question 4

How can I increase my BMR?

Accepted Answer

You can increase BMR by building muscle mass through strength training, staying physically active, eating enough protein, getting adequate sleep, and avoiding crash diets that slow metabolism.

Question 5

Why does BMR decrease with age?

Accepted Answer

BMR decreases with age primarily due to loss of muscle mass (sarcopenia), hormonal changes, and reduced physical activity. After age 20, BMR typically decreases by about 2-3% per decade.
