Factors contributing to your basal metabolic rate

Factors contributing to your basal metabolic rate

Your basal metabolic rate or BMR is the amount of energy ( in calories) that is required to keep you body functioning — maintaining your body temperature, heartbeat, circulation, breathing, and neural functions — while resting for 24 hours. Your BMR represents 60% of the total energy burned each day by your body.

Knowing your BMR is important for a number of reasons. The higher your BMR, the more calories you’re burning on a daily basis which is beneficial if you’re trying to lose weight while adding more lean muscle to your body. Individuals with a lower BMR may be at a higher risk for becoming obese.

Factors contributing to your basal metabolic rate include:

  • Age – BMR decreases approximately 5% each decade after age 40
  • Gender – men have a BMR that is 5 to 10% higher vs women
  • Body size – weight, height, surface area
  • Body composition – fat vs muscle mass; muscle burns more calories
  • Hormonal levels
  • Current health status
  • Exercise
  • Genetics – differences in genetic makeup can affect an individual’s metabolism

BMR estimation formulas

Studies have shown that being able to estimate an individual’s BMR is important when it comes to developing a more effective strategy for achieving weight loss goals. By knowing your BMR, you can change your daily caloric intake and develop an exercise regimen to help meet your goals for losing weight while adding lean muscle mass to your body.

The two most commonly used BMR estimation formulas are the Harris-Benedict Equation and the Mifflin St. Jeor Equation. Both formulas are based upon age, gender, height (cm), and weight (kg), but use a series of different calculations to determine BMR.

Over the years, revised formulas have been employed to take into account changing lifestyles and the difference in metabolic activity between lean body mass vs. body fat in order be better predictors of an individual’s BMR.

Improving your rate

Knowing your BMR can be a valuable tool when it comes to maintaining your optimal weight and overall health. The Ivy Health Labs Body Analysis Scale makes tracking your basal metabolic rate easy, and you can do it from the comfort of your home without complicated formulas that don’t take into account some of the factors contributing to your basal metabolic rate such as sickness, change in activity level, psychological factors such as fear, stress, and anxiety, and genetics.

The Body Analysis Scale provides you with the ability to view your BMR on a daily basis as well as to track it over time to determine any trends in BMR level. This can be a valuable tool when it comes to making lifestyle changes to achieve weight loss goals and to support and maintain lean muscle mass.
