What Exactly Is BMR?

Basal Metabolic Rate, also known as BMR, is the amount of energy your body burns on a daily basis when at rest. To clarify simply, your BMR the number of calories needed to keep your body functioning when you’re not doing any physical activities.

Even when you’re resting and less active your body is using energy. Your body uses energy to make your heart pump blood through your veins and process food in your stomach from your last meal. Your BMR impacts your circulation, cell production, nutrient processing, breathing and other necessities to perform basic life-sustaining functions. This process is known as your basal metabolic rate (BMR) and can be used as the foundation in planning a healthy diet program to safely lose weight and participate in clean eating habits.

Calories are often the first metric to be taken into consideration when losing weight. Understanding the number of calories burning in your body when you’re less active is a great starting point to determine how many calories to burn when exercising and actively moving around. It’s also valuable in discovering how to increase your personal BMR rate.

VeryWellFit has an awesome calculator you can use to see how many calories you burn every day while at rest. While BMR is most accurately measured in a lab setting under restrictive conditions and genetic factors like age, gender and body composition all play important roles in defining your unique basal metabolic rate, the Harris-Benedict Equation formula used to calculate BMR is helpful in providing an estimate. The Harris-Benedict Equation is often used to provide an estimate of the number of calories a person can burn each day based on the following:

                         Men:  BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)

                         Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

If you’d like to improve your personal basal metabolic rate all you need to do is work on building muscle. Start to do exercises that produce body mass and even when your body is resting your lean muscles will begin to burn more calories within a few weeks. Studies have shown an increase in resistance training will increase your unique resting metabolic rate (RMR), a term often used interchangeably with BMR by 7-8%. To speak to a qualified physician to evaluate your basal metabolic rate and healthy ways to increase it based on your lifestyle and fitness goals, schedule an appointment online or call (909) 786-9272 for more assistance.
