BMR is an abbreviation for Basal Metabolic Rate, which is the bare minimum of calories required to sustain the life of a sedentary animal. For example, the BMR is the energy your body would burn if you were asleep 24 hours a day. Certain factors influence how the BMR functions in each individual. How do I find the best age calculator?
Age: Younger people have a higher BMR. Because the metabolic rate slows with age, older people have a different BMR ratio than younger people of the same weight and height.
Height. Taller people have higher BMRs than shorter people.
Body Composition: Even if two people weigh the same, their appearances can differ. Someone may have a lot of lean muscle tissue, while another person may have a lot of fat. In general, this factor is unimportant when calculating a BMR for calorie counting because BMR calculations do not consider your body composition.
It is also important to remember that fasting and starvation can significantly lower the BMR, so if you are calculating this to diet, be careful not to cut back too much.
There are two main methods for calculating your BMR. The first is referred to as the “General Calculation.” In this case, your BMR equals your weight in pounds multiplied by ten. For example, 200 lbs born by ten equals 2000. This is a relatively simple procedure that, combined with a simple calculation for activity levels, should allow you to lose weight through calorie counting. This general calculation, however, is an approximation method. To determine how much, therefore, you need to lose and how much you need to maintain your weight, you must experiment with various techniques.
The Harris-Benedict Equation is a more sophisticated method of calculating BMR. This requires two different ways of calculation, depending on the gender of the person involved. The Equation for a male would be 66 + (13.7 x weight) + (5 x height) – (6.8 x age). So, a 200-pound 27-year-old man who weighs 5.10 has a BMR of 4300. This is the amount he needs to eat to stay at his current weight. If he wanted to lose weight by diet alone, he would eat 3800 calories weekly.
The following Equation yields a woman’s BMR score: 655 + (9.6 x weight) + (1.7 x height) – (4.7 x age). So, a 200-pound, 27-year-old woman who weighs 5.10 has a BMR of 2567.1. This is the amount she would need to consume to maintain her weight. If she wanted to lose weight, she would cut her daily calorie intake by 500 (3,500 calories equals one pound). This would bring her daily information to 2067.1.
On the one hand, you can see the dramatic differences between the two weights. Conversely, you can see the difference between the General calculation and the Harris-Benedict Equation. In practice, the Equation is the best tool for calculating a more accurate BMR for each individual, and it also allows. Individuals recalculate as their weight changes, so you are not always calculating the same amount.
Suppose you believe the Harris-Benedict Equation is not accurate enough for you. In that case, you can measure your BMR in other ways, such as the Underwater Weighing measurement, the gold standard for calculating body composition, or a Skinfold Measurement test, which measures fat folds around the waist, back, and other areas. These are the farthest reaches of the BMR calculation spectrum.
