RMR is slightly higher than BMR, but the difference is less than 10 percent, according to the National Research Council.
1 Because men, on average, have a greater muscle mass and a lower body-fat percentage than women, they generally have a higher basal metabolic rate. 2  Age. 3  BMR is greater in childhood than in adulthood. 4  After age 20, BMR is estimated to drop about 2 percent to 3 percent each decade.  i was looking at this sites calculators and i thought i saw something that looked a little strange...when i calculate my BMR and RMR the BMR is always higher. Now i'm a little confused about this because your BMR (basal metabolic rate) is just the amount of the calories you need in a day. However your RMR (resting metabolic rate) is the amount of calories your body needs if you just slept all day.  When comparing calorie estimations, RMR is slightly higher than BMR, but the difference is less than 10 percent, according to the National Research Council. While both RMR and BMR are considered estimations of your calorie needs, BMR is a more accurate measure because of the stricter procedures required to obtain it. What's Measured. Both BMR, and RMR, estimate the number of calories you burn at rest, but RMR takes additional factors into consideration when determining needs. BMR measures your basal energy expenditure, or BEE. The amount of energy (in the form of calories) that the body needs to function while resting for 24 hours is known as the basal metabolic rate, or BMR. This number of calories reflects how much energy your body requires to support vital body functions if, hypothetically, you were resting in bed for an entire day.  So right now my BMR/RMR is 2399 * 1.3 - 500 = so about 2600 calories. I eat about 3100 calories a day right now and exercise about 500-600 so I try to stay in +/- range of 100 cals and my body fat went down nearly 4% in 3 months. A few months ago, I paid to have a resting metabolic rate test at my gym. I came in early in the morning on an empty stomach and reclined in a chair for about 40 minutes in a dark room while hooked up to a machine. My RMR came out at 1777. However, when I go online and do a BMR, I get 1492. Resting metabolic rate is the energy required by an animal to stay alive with no activity. Therefore, your real metabolic rate is always significantly higher than your RMR. Calculating RMR is a very useful first step in calculating your real metabolic rate. Resting metabolic rate is really what most lay people mean when they say basal metabolic rate, and I talk here only about resting metabolic rate (RMR). Basal metabolic rate is a precise calculation with a precise definition; RMR is close enough for practical purposes Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest. (McNab, B. K. 1997). On the Utility of Uniformity in the Definition of Basal Rate of Metabolism. Physiol. Zool. Vol.70; Metabolism refers to the processes that the body needs to function. Your basal metabolic rate accounts for about 60 to 75% of the calories you burn every day. 1. Basal Metabolic Rate. The biggest contributor to metabolic rate is resting energy expenditure, also known as Basal Metabolic Rate (BMR). Your BMR is the amount of calories you would need if you laid in bed all day and didn't move. In other words, it's the amount of energy your body needs just to keep you alive and perform basic functions like breathing, keeping your heart beating and maintaining your body's tissues.
