Check your BMR (Basal Metabolic Rate) using this Mifflin-St Jeor BMR Calculator below to get the estimated number of calories you need daily to maintain your body weight.
BMR CALCULATOR
*Sedentary means little or no exercise
*Lightly active means light exercise/sports 1-3 days/week
*Moderately active means moderate exercise/sports 3-5 days/week
*Very active means hard exercise/sports 6-7 days a week
*Super active means very hard exercise/sports & physical job or 2x training
*Before using the data obtained using this calculator, please consult with a doctor.
If you choose BMR as your activity level, you will get the estimated number of calories your body burns while at complete rest.
However, if you choose a physical activity between Sedentary and Super active, your original BMR is multiplied by an activity factor. And you will get a more realistic value of how many calories your body needs daily for maintaining your body weight.
By the way, your BMR is the number of calories your body burns at rest to carry out all of the biological activities (like breathing, digestion, pumping of blood, etc) to do to keep you alive and functioning properly.
How do you use The result
Once you get your caloric maintenance estimate, you can either:
- Consume about that number of calories daily to maintain your weight
- Consume LESS than that number of calories daily to lose weight
- Consume MORE than that number of calories daily to lose weight
BMR Calculator Formula
There are various equations from different scientists that attempt to calculate the BMR number, which is also referred to as Resting metabolic rate (RMR).
However, the Mifflin-St Jeor Equation is considered one of the more accurate and widely accepted equations used for calculating BMR (or RMR)
The above calculator uses the Mifflin St. Jeor equation to find the Basal Metabolic Rate.
The calculator also factors in activity level to estimate how many other calories are burned daily in addition to the BMR.
Your activity level is also factored in to estimate how many other calories you burn per day in addition to your BMR. The amount given is the total of the two and should be, which estimates your maintenance level.
Mifflin St. Jeor derived this formula to find the Basal metabolic rate:
For Men : 10 x weight (kg) + 6.25 x height (cm) – 5 x Age + 5
For Women : 10 x weight (kg) + 6.25 x height (cm) – 5 x Age – 161
