Your resting metabolism rate is a measure of how well your body uses the energy sources you consume when it is at rest. While a healthy resting metabolism rate is mostly dependent on the individual in question and their muscle mass and body size, the average RMR for men is above 1600 calories per day for men and 1400 calories per day for women. The difference in metabolic rate between men and women is mostly due to differences in muscle mass. As such, it is not a cut and dried statistic. When you come to Transform Alliance for Health, one of our doctors can determine a target resting metabolic rate for you, given your weight, age, and muscle mass.
