A caloric deficit is required to lose weight. But because most people do not have access to state-of-the-art labs that are required to determine BMR, equations are often used to make approximations. The easiest way to measure your metabolic rate is to use an online calculator. You can find many calculators online, and all use varying equations.
The commonly used metabolic equation, called the Harris and Benedict equation, was first designed in and updated in While it was intended to estimate BMR, it actually estimates RMR, according to the NASM. It uses height, weight, biological sex, and age to determine RMR and is based on average lean mass levels.
The Mifflin-St Jeor equation is another equation that uses the same variables but may be more accurate, Church says. Other metabolic equations, such the Cunningham equation, use your total levels of lean body mass, which is a primary determiner of BMR and therefore RMR.
Calipers and smart scales are two popular at-home options, while the most accurate measures are performed in professional and laboratory settings.

For example, if a female pounds, 5'3", 36, and her body-fat percentage is 25 percent, her RMR is 1, calories.
BMR or RMR can be used to estimate total daily caloric expenditure. According to the American Council on Exercise , after you determine your RMR, based on one of the above equations or an online calculator, you can multiply it by one of the numbers below, called activity factors:.
If the man in the above example exercises two days per week, his daily caloric expenditure is roughly 2, to 2, calories. If the woman in the above example exercises six days per week, her daily caloric energy expenditure is roughly 2, to 2, calories.
