The BMR is a more restrictive measurement of the energy your body uses for basic functions (such as breathing, blood circulation and organ functions) whereas the RMR is your energy expenditure during a normal resting or non-exercising state ie. Genetics: Some people have higher BMR due to their genes and also many genetic defects.ĭifference Between Basal Metabolic Rate and Resting Metabolic Rateīasal metabolic rate (BMR) and Resting metabolic rate are both ways of assessing the calories used by your body to perform various metabolic activities. Hormonal factors: Hormonal imbalances like thyroid disorders can increase or decrease your BMR.ĭiet: Foods highly affect your metabolic rate - "You are what you eat"! While some foods increase your BMR, others would reduce it.ĭrugs: Drugs like caffeine, and nicotine can increase your BMR as they power up your metabolism. Physical activity: Physical activity increases your muscle mass, hence more calories would be required in carrying out simple metabolic reactions, therefore raising your BMR.Įnvironmental factors: Extreme environmental conditions like high hot or cold temperatures can make your body work harder to maintain the normal temperature, thus increasing BMR. Gender: Men usually have a faster metabolism than women and hence have BMR higher than women. Muscle mass: Having high muscle mass increases calorie usage due to high surface area and therefore, you need high BMR with increased muscle mass.īody size: People with larger bodies and high weight have high BMR because they have big organs and fluids to metabolize and support. Thus, you would find having low BMR as you age. Factors that Affect Basal Metabolic Rateīelow are a few of the factors that affect basal metabolic rate,Īge: Your metabolism slows down as you age because of the loss of muscle tissues, and also due to molecular changes that occur in neurological and hormonal systems. A higher BMR indicates that you have an active metabolism and need more calories to sustain yourself. Knowing the BMR helps you in knowing the calorie requirements of your body for performing the most sedentary activities. ![]() ![]() What is Basal Metabolic Rate?īasal metabolic rate is the number of calories that are burnt when you perform basic activities (ie., while resting). Read on to know these to level up your knowledge of fitness and health. Here you would know what these words mean to your fitness goals. ![]() If you are a fitness enthusiast, you would have probably heard BMR, BMI or RMR almost repeatedly. Calories have always been the talk of the town since the day fitness took over the front seat in the minds of people.
