Calculating your BMR
(Basal Metabolic Rate)

Print this page

BMR, or Basal Metabolic Rate, is the minimal amount of calories needed just for living. It is different for each of us. Basal Metabolic Rate measures calories used when one is sleeping or sedentary, for brain activity and carrying on bodily functions.

We can do little to change Basal Metabolic Rate and it declines with age. The BMR for men will be higher than for women.

In addition, we burn about 10% of our daily caloric intake just digesting our food. This is called the Thermal Effect of Feeding or TEF. To figure your baseline calorie need, BMR plus TEF, multiply your weight (in pounds) by 9. For instance, a 40 year old women weighing 150 pounds, has a baseline calorie need of 1350 calories per day. If she wants to eat more, she has to move her body. Everything counts.

Some activities burn more calories than others. If she goes for a 30 minute run, she will burn more than if she plays the piano. She will burn more if she goes out dancing than if she goes to the opera.

Her more strenuous activities have an added bonus called EPOC, Excess Post-exercise Oxygen Consumption, the after-burn from a workout. It can be 30 to 200 calories, depending on her own unique metabolism and how hard she worked.

As I said, we are all different, but you can work with this method and figure out how many calories you need. Multiply your weight by 9.

Journal your activities each day. After you have figured out how many calories you need for the day, eat 500 less and let your body burn some of it’s stored fat.


Daily Activity Calories Burned/Hour
Sleeping 90
Lying Quietly 90
Sitting 115
Light Work 250
Exercise moderate vigorous
Backpacking 400 550
Bicycling 175 400
Callithenics 300 875
Dancing 285 550
Running 550 1090
Walking 250 (3 MPH) 490 (5 MPH)
Weight Training 470 N/A

(These figures are approximate, but they serve our purposes.)


Journal entry for 40 year old woman who weighs 150 pounds.

Basal Metabolic Rate: 150 X 9 = 1350 calories needed daily
One hour run, 5 miles-----------550 calories burned
EPOC--------------200 calories burned,
Total calories needed---2100 calories

Minus 500 calories to lose 1-2 pounds/week = 1600 calories


Multipling your weight by 9 may not work for you. You may need to multiply by 8, or by 10. Play around with this until you know how your own unique metabolism works.
