It decreases when you lose weight because your body requires fewer calories to burn daily. Taller and heavier individuals typically have higher BMR. This means men generally have faster metabolisms or higher BMR. And the more mass you have, the more energy you need to sustain your body. Muscles require more energy to maintain compared to fat cells. The National Health Services (NHS) states men biologically have more muscle mass, less body fat, and higher bone density compared to women. Why is BMR different for men and women?īody composition is different for men and women. In this example, the woman's basal metabolic rate is 1,307.055 calories per day. Look at the example below to see how it's done.īMR = 655.1 + (4.35 × weight in pounds) + (4.7 × height in inches) – (4.7 × age in years) Women: BMR = 655.1 + (4.35 × weight in pounds) + (4.7 × height in inches) – (4.7 × age in years)įor a faster way to get your BMR, use the above calculator. Men: BMR = 66 + (6.2 × weight in pounds) + (12.7 × height in inches) – (6.76 × age in years) Only after can a specialist measure your oxygen and carbon monoxide levels to calculate your resting metabolic rate. This requires 24 hours of rest, including 12 hours of fasting and 8 hours of sleep. The most accurate way to measure BMR is still through a lab test. Take note: The formula is just an approximation. Benedict developed a BMR equation by simply plotting the following information: Manini, program director for Geriatric Informatics at the University of Florida. How is BMR related to muscle mass? BMR typically declines by 1% to 2% per decade after age 20, mostly because of muscle loss, according to research by Dr.

Metabolism refers to all physical and chemical bodily processes that convert or expend energy. Healthline states RMR should still be an accurate estimate of the body's BMR. RMR slightly differs from BMR, with RNR including energy expended by simple daily movements. This includes breathing, blood circulation, cell production, and nutrient absorption.īMR is often used interchangeably with Resting Metabolic Rate (RMR), which is the number of calories the body burns while at rest. What is Basal Metabolic Rate (BMR)?īasal metabolic rate (BMR) is the amount of energy the body burns to accomplish basic life functions. Apart from tracking your metabolism, it allows you make smarter weight management strategies. This significantly lowers the body's resting metabolism, which makes people prone to weight gain and age-related diseases.īut the good news is you can calculate your basal metabolic rate. Aside from shedding excess fat, it's important to maintain muscles as you age.Īfter 30, adults start to lose 3% to 5% of muscle mass per decade.
