Only then can an expert calculate your resting metabolic rate by measuring your oxygen and carbon monoxide levels. This necessitates a total of 24 hours of sleep, including 12 hours of fasting. A lab test is still the most accurate technique to determine BMR. The amount of energy your body needs to conduct its basic (basal) life-sustaining processes is referred to as your basal metabolic rate. With the help of our simple Basal Metabolic Rate Calculator, you can calculate BMR in no time.Įven when you’re sleeping, your body burns calories by executing basic life activities like: So it’s critical for everyone to know how to calculate BMR. Moreover, if this necessary quantity of calories is not obtained, your basal metabolism will slow down. To put it another way, this is the quantity of energy you require to live a healthy life. The number of calories consumed by the body is known as BMR (Basal Metabolic Rate) when it is at rest. 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 largest component of a person’s total caloric needs is usually their basal metabolism. A person’s sympathetic nervous system must be inactive for a reliable BMR assessment, which means the person must entirely sleep. While awake, the BMR is tested under very tight conditions. As a result, using our Basal Metabolic Rate Calculator to gain an understanding of BMR is preferable. Your body won’t be able to carry out its essential activities. Calculating BMR is crucial because if you don’t know how many calories your body requires, you may get fatigued. Basal Metabolic Rate (BMR) is a term that refers to how much muscle mass a person possesses. Please remember to consult a medical expert if you are looking to gain or lose a lot of weight.The BMR Calculator, or Basal Metabolic Rate Calculator, is a tool that determines how much energy your body needs to stay alive. If you are looking to gain or lose weight, you can also use this number as a point to eat more or less then, respectively. Thanks to the Harris-Benedict calculator and Harris-Benedict equation you can know the perfect amount of calories to eat if you want to keep your body weight as it is. Keeping a healthy diet and using the Harris-Benedict calculator to keep an eye on your BMR will make it easier for you to stay in good health. If you are extra active (very hard exercise/sports & a physical job) : Calorie-Calculation = BMR x 1.9įor more on BMR, check out the BMR Calculator, Basal Metabolic Rate and the Mifflin St Jeor Equation.Very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725.Moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55.Lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.Sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2.To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: How to determine the Harris-Benedict equation? The Harris Benedict Equation is a formula that uses your BMR and then applies an activity factor to determine your total daily energy expenditure (calories). The calculators for both sexes are as follows:įor men: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5įor women: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161 How can you calculate your BMR?Ĭalculating your basal metabolic rate is easy all you need to measure is your weight and height, although your age and sex also come into play. You Basal Metabolic Rate (BMR) is equivalent to the amount of energy (in the form of calories) that your body needs to function if it were to rest for 24 hours.
