2. Age – Age plays a crucial factor in deciding your BMR. As you grow older your metabolic rate slows down due to the decrease in muscle mass.

3. Physical Activity – Exercising more and on a regular basis can help increase your metabolic rate as your muscles burn calories at a faster rate.

For men – BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)

For women – BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
