Below is the Mifflin St. Jeor Calculator. The Mifflin St. Jeor formula can be located under the calculator.
Directions for using the calculator:
1- Select your sex
2- Enter in your weight and select lbs or kgs
3- Enter in your height and select inches or cm
4- Enter in your age.
You now have your BMR. Next you will want to multiply your BMR by your activity multiplier, you can get this from the filling out activity quiz from the Fat Loss Troubleshoot.
5- Select your activity multiplier from the drop down menu.
Once done, you’ll see 3 different estimates of your burn. The first number is your BMR multiplied by (activity multiplier you selected minus 0.10) you selected. The second number is your BMR multiplied by the activity multiplier you selected. The third number is your BMR multiplied by (activity multiplier you selected plus 0.10). I wanted you to see the three different numbers to get a better understanding of the range you should be in.
Below are the formulas:
10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5
10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) – 161.
