What is a good basal metabolic rate?

Once you know your RMR, you might be tempted to compare your number to the RMRs of other people around you. And you might wonder if your RMR is normal. According to several sources, the average RMR for women is around 1400 calories per day1 and for men is just over 1600 calories.

What is the average metabolic rate?

Basal Metabolic Rate

BMR calculations use a person’s age, height, weight and gender to find the number of calories burned in a day. For women, the average BMR in the United States is 1,493 calories. For men, the average BMR in the United States is 1,662 calories.

What is metabolic rate in biology?

An organism’s metabolic rate is the amount of energy expended by that organism in a given time period – usually daily. At rest, meaning in periods of inactivity, the metabolic rate is known as the basal metabolic rate (BMR). At rest, the BMR is low compared to when the body is undergoing activities like exercise.

How do you know your metabolic rate?

There are 2 formulae used to calculate BMR, in [kcal / 24hrs] for men and women respectively:

  1. BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years])
  2. BMR for Women = 655.1 + (9.563 * weight [kg]) + (1.85 * size [cm]) − (4.676 * age [years])
