Basal Metabolic Rate: BMR Calculator
Basal Metabolic Rate (BMR) is the minimum number of calories your body needs to stay alive and you can use a BMR Calculator to figure it out. Your body needs calories for metabolic functions which include breathing, circulation, digestion, and maintaining muscle mass and bone strength. Keep in mind that BMR is the number of calories you burn at rest. Walking or exercising, in fact, any movement will require additional calories above those needed to support your BMR. Your individual BMR value is not constant, it is dependent on your age, sex, height, and weight.
Why is calculating your BMR important?
Your basal metabolic rate is important when planning a weight loss (or weight gain) program. Once you know your BMR, you can adjust your calorie intake by either consuming fewer calories to lose weight or more calories if your goal is to gain weight.
How to use the BMR calculator.
The BMR calculator provides an accurate number of calories your body requires daily to sustain itself based on your current lifestyle and these factors: age, height, weight, and gender. For example, if you are male, 30 years old, 70 inches tall, and weigh 200 pounds your BMR equals 1874 calories. Note that when entering your data, your weight must be in pounds and height in inches.
Using your BMR to plan your goals.
Your BMR provides a starting point for planning your weight loss or weight gain program. Remember, your BMR is the number of calories your body burns at rest and does not take into account the calories you need to move, walk or exercise, etc. When planning your diet for losing weight or gaining muscle, it will be beneficial to use your BMR number to calculate your Total Daily Energy Expenditure (TDEE) which estimates your activity and energy level.
