What is BMR?
BMR stands for Basal Metabolic Rate, the minimum calorific requirement needed to sustain life in your body when you are resting. It is also called Resting Metabolic Rate (RMR).
Even if you are in bed asleep all day, your body still needs energy to pump blood around the body, maintain body temperature, etc.
Does BMR formula include my activity level?
No, it does not. Basal Metabolic Rate is estimated using your weight, height and age (see BMR formulas below). BMR is gender specific. BMR Calculator prompts you to enter your activity level in order to calculate the number of calories you need daily to maintain your current weight.
What is BMR formula?
English BMR Formula:
Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years )
Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in years )
Metric BMR Formula:
Women: BMR = 655 + ( 9.6 x weight in kilos ) + ( 1.8 x height in cm ) - ( 4.7 x age in years )
Men: BMR = 66 + ( 13.7 x weight in kilos ) + ( 5 x height in cm ) - ( 6.8 x age in years )
Is it possible to raise your Basal Matabolic Rate?
Yes, it is. For details, please see "How to increase metabolism?".
question
I am 23 weigh about 140/145 in that range and am working out 4-5 days a week for 45 minutes or so with weights and cardio. I used to weigh much less but over the past 2 years put on the weight so I am trying to lose it in a healthy normal way w/o going on a fad diet. Using the BMR calculations I came up with 1478.45 calories. So, is that what I should consume in order to lose weight? (Because I exercise)? My ideal weight for 5'4' is around 120lbs...
BMR
BMR is not the number of calories you should consume in order to lose weight. It is the number of calories required to maintain the basic functions of your body (merely living and breathing). BMR is required to calculate the number of calories your body needs to maintain your current weight (for you, it is about 2250) Deduct 500 calories from this number and you get the number of calories you need to eat a day in order to lose a pound per week (in our case, we get 1750).
response to question
to lose weight, you will need to consume less than your BMR, eating 1200 calories/day will get you to the 120lb weight you desire. My advise is to do it eating an adequate diet. (all types of foods in proper proportions). I am a 23 y/o female, i used to weigh 136 but now weigh 115 doing exactly this. eat your fruit and veggies too!
Warning
1200-calorie diet may be too low for some people. You should always consult your doctor before trying it.
