The BMR Calculator, or Basal Metabolic Rate Calculator, is a tool that determines how much energy your body needs to stay alive. Basal Metabolic Rate (BMR) is a term that refers to how much muscle mass a person possesses. Calculating BMR is crucial because if you don’t know how many calories your body requires, you may get fatigued. Your body won’t be able to carry out its essential activities. As a result, using our Basal Metabolic Rate Calculator to gain an understanding of BMR is preferable.
While awake, the BMR is tested under very tight conditions. A person’s sympathetic nervous system must be inactive for a reliable BMR assessment, which means the person must entirely sleep. The largest component of a person’s total caloric needs is usually their basal metabolism. The daily calorie requirement is calculated by multiplying the BMR by a factor ranging from 1.2 to 1.9, depending on activity level.
The number of calories consumed by the body is known as BMR (Basal Metabolic Rate) when it is at rest. To put it another way, this is the quantity of energy you require to live a healthy life. Moreover, if this necessary quantity of calories is not obtained, your basal metabolism will slow down. This will result in body exhaustion. So it’s critical for everyone to know how to calculate BMR. With the help of our simple Basal Metabolic Rate Calculator, you can calculate BMR in no time.
Even when you’re sleeping, your body burns calories by executing basic life activities like:
- Production of cells
- processing of nutrients
The amount of energy your body needs to conduct its basic (basal) life-sustaining processes is referred to as your basal metabolic rate.
The Formula for BMR Calculator
The formula is only a rough estimate. A lab test is still the most accurate technique to determine BMR. This necessitates a total of 24 hours of sleep, including 12 hours of fasting. Only then can an expert calculate your resting metabolic rate by measuring your oxygen and carbon monoxide levels.
The Harris-Benedict BMR formula is a formula devised by Harris and Benedict:
Men: BMR = 66 + (6.2 × weight in lbs) + (12.7 × height in inch.) – (6.76 × age in yrs)
Women: BMR = 655.1 + (4.35 × weight in lbs) + (4.7 × height in inch.) – (4.7 × age in yrs)
Use the calculator above to calculate your BMR faster.
Look at the example below to see how it’s done.
- Age: 30
- Gender: Female
- Height: 62 inches
- Weight: 115.3 lbs.
BMR = 655.1 + (4.35 × weight in lbs) + (4.7 × height in inch.) – (4.7 × age in yrs)
655.1 + (4.35 x 115.3 lbs.) + (4.7 x 62 inch.) – (4.7 x 30)
655.1 + 501.555 + 291.4 – (141)
= 1,448.055 – 141
BMR = 1,307.055
In this example, the woman’s basal metabolic rate is 1,307.055 calories per day.
The Basic Metabolic Rate (BMR) for Weight Loss
You can calculate your daily calorie requirements using our online basal metabolic rate calculator. The result helps you to “calorie-count.” To stay in a calorie deficit, maintain your calorie intake lower than your basal metabolic rate for weight loss. In theory, you can lose weight without engaging in any physical activity.
Exercise, of course, will boost your basal metabolic rate and help you burn more calories. We offer a specific online calorie calculator for this purpose that takes into consideration your sporting activity. As well as, determines your basal metabolic rate as well as the calories you actively require.
In general, as weight is lost, the metabolic rate, and thus the basal metabolic rate, lowers slightly. One of the reasons for this is muscle loss as a result of dieting. You can counteract muscle loss by doing weight lifting or general fitness training in addition to a diet. Adequate exercise is necessary and should be considered. When on a diet, to keep the body and metabolism running smoothly exercise adequately.
Factors affecting BMR
The list of things that may have a direct or indirect yet significant impact on your BMR is extensive. We’ll go through a couple of the elements that influence BMR in this section:
- The most essential element in most body-related indices and ratios, such as BMR, RMR, and BMI, is age. When determining BMR, the first thing you need to know is your age. BMR is directly related to age, and BMR is inversely proportional to age. Therefore, the greater the age, the lower the BMR.
- Gender: When calculating BMR, another aspect that determines your BMR is your gender. Because men have more muscle mass than women, their BMR is usually higher.
- Daily Activity: This is the aspect that has an impact on BMR numbers. Your BMR will be high if you are active and exercise on a daily basis. On the other side, if you don’t have an active habit and don’t care about exercise. Your BMR will be significantly lower than that of an active person.
- Climate and body temperature: People who live in tropical regions tends to have a 5-20% greater BMR than those who live in hotter climates. This happens so because it requires more energy to keep the body cool. Remember that exercising or engaging in physical activity in hot conditions adds to your metabolic load.
- Levels of Hormones: Thyroid hormones release a crucial hormone that has a substantial impact on BMR. Hypothyroidism is a rather prevalent condition, particularly in women nearing or beyond menopause. A person with a weight problem and a low thyroid function should also seek medical care.
Understanding your BMR, average activity level, and the number of calories you require daily are all crucial aspects of your physical well-being. Calculating your BMR is a fantastic place to start. It helps to know whether you need to gain weight, maintain your current weight, or reduce weight.
This BMR Calculator is a simple tool that allows you to figure out how many calories your body would require if you were to rest for the entire day. The Basal Metabolic Rate Calculator calculates your BMR score based on your age, height, weight, and gender. Continue reading to learn more about BMR, how to calculate it, BMR formulas. We’ll also go over the differences between calculating a male’s BMR and estimating a female’s BMR.
BMR = 1766 calories per day
Experts estimate that the RMR value accounts for 50 percent to 70 percent of a person’s daily energy expenditure. Keep in mind that beyond the age of 20, your BMR slows down by around 2% every ten years. That’s one of the key reasons why most people gain weight as they age while eating the same amount of calories.
It is very simple and easy, you can readily do the math yourself with the ease of the given equation:
If you are a man, then;
BMR = (6.23 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in years)
Weight = 170 pounds
Height = 5’11’’
Age = 43
BMR = 66 + (6.23 x 170) + (12.7 x 71) – (6.8 x 43) = 1,734.4 calories
If you are a woman, then;
BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years)
Weight = 130 pounds
Height = 5’3’’
Age = 36
BMR = 665 + (4.35 x 130) + (4.7 x 63) – (4.7 x 36) = 1,357.4 calories
