Metabolic age is connected to calories consumed by metabolic system. It is directly dependent on BMR (Basal Metabolic Rate). BMR is amount of calories consumed by our metabolism when our body remains at rest. Its calculation is different for different genders. Here we have given the formula usually used to calculate BMR. Here can calculate you BMR after filling the details in the form given below.

The above formulas are not used in modern calculations of BMR. Now we use a more accurate formula known as

### Metabolic Age

**Metabolic age**is actually a comparison of BMR of people of similar age group. If your BMR falls in the range of average BMR of other age then your Metabolic Age will be that. So your metabolic age can be different from your actual age. To keep your Metabolic age below your actual age you need to control your weight. Weight is the only factor that you can control. Height and actual age can't be controlled by anybody. Our BMR increases till the age of 20 and then starts decreasing 100 Calorie per decade.### BMR (Basal Metabolic Rate)

The formula given below is known as Harris-Benedict formula, which was created in year 1919.**BMR for women**= 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age in years )**BMR for men**= 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) – ( 6.8 x age in year )The above formulas are not used in modern calculations of BMR. Now we use a more accurate formula known as

**Mifflin - St Jeor formula**, which was created in 1990. Mifflin - St Jeor formula is given below.**BMR for men**= (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5**BMR for women**= (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
