6/22/2023 0 Comments Bmr calculator kg cm![]() ![]() The amount that a person needs in a day is also dependent on the amount of activity they get on a given day, so it varies day by day, and is difficult to measure. department of Health estimates that adult males require approximately 2000-3000 calories per day to maintain weight, while adult females require approximately 1600-2400. The number of calories a person needs in a day varies widely depending on a number of factors such as age, weight, height, sex, physical activity level, general health, and more. Realistically, we are not usually completely at rest, so the number of calories we actually burn throughout the course of a day is most likely higher than this number. This means that while completely at rest, this woman would burn 1224 calories worth of energy. The Mifflin St Jeor equation uses the height (H in centimeters), weight (W in kilograms), and age (A in years) of a person to estimate BMR, and slightly differs for men and women.įor example, a 33-year-old woman who weighs 55 kg and is 160 cm tall has an estimated BMR of:īMR = 10×55 + 6.25×160 - 5×33 - 161 = 1224 For those who have an accurate estimate of their body fat percentage, the Katch-McArdle formula may provide a more accurate estimate of BMR. The calculator on this page uses the Mifflin St Jeor equation. How is BMR estimated?īMR is estimated using several different equations. to maintain weight, consume the same number of calories as your BMR.Įveryone's circumstances are different however, and while the above works in theory, it may not work for everyone.to gain weight, consume more calories than your BMR.to lose weight, consume fewer calories than your BMR. ![]() The equation used by this calculator to estimate BMR is the Mifflin St Jeor Equation (discussed below).īMR is commonly used as a way to measure the number of calories you need to consume per day in order to lose weight, gain weight, or maintain your weight. A significant amount of research has been done surrounding estimating BMR, and a number of different equations have been developed for this purpose, such as the Mifflin St Jeor Equation, the Harris-Benedict Equation, and the Katch-McArdle formula. BMR and REE are often used interchangeably, because while their definitions differ, they can be used to estimate each other.īecause BMR requires strict conditions to properly measure, such as being awake but completely at rest, it is usually estimated instead. This is also a good estimate of your resting energy expenditure (REE), which is the amount of energy you burn over time while at rest. ![]() Your basal metabolic rate (BMR) is the amount of energy that your body requires in order to perform these base functions. To use the calculator, please provide your age, weight, height, activity level, and click the "Calculate" button.Įven while at rest, your body still expends energy to perform functions such as breathing, circulating blood, processing nutrients, producing cells, and more. This calculator is intended for adults between the ages of 18 and 80 years old. Add 500 calories to the total to gain around 1lb per week or deduct 500 calories to lose roughly 1lb per week.This BMR calculator estimates the Basal Metabolic Rate (BMR) of a person based on age, sex, body weight, and body height. If your goal is to maintain your current weight, eat this amount. Obviously, these are rough guides, so you may need to play around with the numbers to better suit your needs as you go along. He number you get is the number of daily calories you need in order to maintain your current weight. Very active. If you take part in hard exercise six to seven days per week, multiply your BMR by 1.725.Įxtra active. If you engage in very hard exercise six to seven days per week or have a physical job, multiply your BMR by 1.9. Moderately active. If you moderately exercise three to five days per week, multiply your BMR by 1.55. Lightly active. If you lightly exercise one to three days per week, multiply your BMR by 1.375. Sedentary: If you get little or no exercise, multiply your BMR by 1.2. To include the number of calories you burn during daily activities based on your lifestyle, use the following multiplications: This will make sure that you allow for the extra calories needed for things like walking around, playing sports, training and rebuilding muscle through hypertrophy. Once you’ve got your BMR, you need to multiply it by your activity level. ![]()
