The Katch-McArdle Formula is slightly different in that it calculates resting daily energy expenditure RDEEwhich takes lean body mass into account, something that neither the Mifflin-St Jeor nor the Harris-Benedict Equation does. BMR stands for basal metabolic rate.

Metabolic rate calculation -

Because the terms are similar, some fitness and weight loss experts use both terms to describe the same thing. But the term "resting metabolic rate" is more common. If you are looking to reach or maintain a particular weight, you may find it helpful to have a BMR calculation.

You can find the number using a formula designed by scientists, get it tested in a lab, or you can use an online calculator. No method is perfectly accurate, but a lab test will probably give you the best estimate. Put your height, weight, and age into our online calculator to find your basal metabolic rate with the addition of daily activity.

The calculator provides an estimate of the total number of calories you burn daily. Once you understand BMR and get a reasonable estimate of your number, you can use it to help you reach or maintain a balanced weight.

First, you can try to increase your basal metabolic rate; then, you can increase the total number of calories you burn each day to help you reach your goal.

A combination of factors determines your basal metabolic rate. Genetic factors, age, sex, and body composition play a role. There's not much you can do to control genetics, age, or sex. But you can change your body's fat-to-muscle ratio to boost your metabolism.

You can use body fat monitors to help determine how much of your body weight is made up of fat compared to muscle, bone, organs, and other tissues. One way to change your body composition is to build muscle. Even when your body is at rest, lean muscle mass will burn more calories than fat.

And you don't even have to be a bodybuilder to see the benefits. The total number of calories you burn daily heavily depends on your basal metabolic rate.

But you can also burn more calories each day by making changes to your eating plan and activity level. Your basal metabolic rate and two other factors can give you an idea of the total number of calories you burn each day.

If you can burn more calories than you consume, you will create a calorie deficit or negative energy balance. If you burn fewer calories than you consume, you will create a positive energy balance and gain weight. Learning about your basal metabolic rate and the total number of calories you burn daily is a positive step in reaching or maintaining a healthy weight.

You can also use smart scales at home to measure and keep track of your weight, as well as BMI, muscle mass, and body fat percentage.

The more you know, the easier it is to make changes in your life that produce actual results. It is also important to talk to a healthcare provider, like a registered dietitian, to determine what is right for you. They can evaluate your medical history and nutrition goals and help you develop a plan that is right for you.

Mayo Clinic: Metabolism and Weight Loss: How you burn calories. Aristizabal JC, Freidenreich DJ, Volk BM, et al. Effect of resistance training on resting metabolic rate and its estimation by a dual-energy X-ray absorptiometry metabolic map.

Eur J Clin Nutr. Pethusamy K, Gupta A, Yadav R. Basal metabolic rate Bmr. Table of contents: What is a BMR calculator? How can you calculate your BMR? What is the Harris-Benedict equation? How to find your total daily calorie needs using Harris-Benedict equation?

What is a BMR calculator? FAQ How do I calculate my BMR? What is BMR? What does BMR mean? What is a good BMR? How do I increase my BMR? To increase your BMR basal metabolic rate , you can try: Eating more protein in every meal.

Doing more HIIT high-intensity interval training workouts. Increasing your daily activity — choose stairs over the elevator, walk more, switch to a standing desk.

Eating more spicy foods. Doing more resistance workouts — muscles burn more calories than fat tissue. How do I calculate BMR in pounds? To calculate your basal metabolic rate in imperial units, use the equations: For men: How do I use BMR to lose weight?

Is the Harris-Benedict equation accurate? How do I calculate my BMR as a female? To calculate your female BMR, you need to: Know your exact weight and height. Don't cheat - it will only make the results inaccurate. The result is your basal metabolic rate — BMR. You can then multiply it with your physical activity level — PAL — to find your total daily energy expenditure — TDEE.

Although direct and indirect calorimetry provide accurate estimates of RMR , these techniques are expensive , time consuming and difficult to access. As a result, more accessible and affordable techniques that estimate RMR have been developed over the past years.

They measure this value with varying degrees of accuracy. Perhaps the most common methods utilized today are mathematical formulas.

You can access these with calorie calculators on the Internet, an app or through wearable devices. NASM Online Calorie Calculator. While it was intended to measure basal metabolic rate BMR or basal energy expenditure BEE , they are used interchangeably with RMR. The Mifflin-St Jeor equation , created in the s, provided an alternative and more valid estimate of RMR 3.

At first, this error appears small i. Furthermore, these formulas also imply that all individuals of the same gender, age, height and weight have the same RMR, a fact that is certainly not accurate.

Your lean body mass will significantly influence RMR and should always be considered. Although the Katch-McArdle and Cunningham formulas are derived from lean body mass rather than total body weight, they rely upon an accurate measurement on lean body mass.

Although newer equations continue to emerge e. Genetics and epigenetics can also play a significant role. Over different genes have been identified by scientists that are related to obesity.

The fat mass and obesity-associated gene, the FTO gene , can cause people to overeat due to low satiety 7. Eating behaviors associated with a low satiety include eating larger portions, preferring calorie-dense foods high in fat and sugar, enjoying palatable foods like appetizers and snacks, and snacking more frequently.

This FTO gene can also alter RMR by up to calories per day — this amounts to almost 17 pounds 7. Epigenetics is the field of study that examines inheritable changes within our genetic expression that occurs without change to our underlying DNA sequence.

It is both a regular and natural occurrence and is influenced by age, environment, diet, geographical location, lifestyle and disease. Research continues to examine potential links between epigenetics and TDEE considering how it can influence food uptake and overall metabolism — possibly altering RMR by a few percentage points or to calories daily 8.

This list is potentially endless, but the reality is that most fitness professionals usually limit their strategies to exercise, macronutrients , calories and various stimulants.

Building lean body mass is another effective method for boosting RMR. Peak muscle mass in humans usually occurs at ages to after which muscle losses begin to occur.

The ability to preserve muscle mass or even better, build muscle mass can help preserve our age-related losses. per year. It might interest you to know that even a lack of sleep i. Thirty years of research demonstrates how the practice of eating very low caloric intakes e.

Under this stress, sustained, elevated levels of cortisol can suppress thyroid stimulating hormone production which will ultimately impact thyroid hormones that regulate metabolism.

Furthermore, these starvation states can also waste away valuable muscle mass which in turn will also reduce RMR. For more on hormone production and how it pertains to metabolic function , follow the link. So, how do you gauge whether you are in starvation states where RMR might be negatively impacted?

Unless true RMR is known which can set a minimal threshold for daily caloric intake, you might just be guessing with mathematical formulas even though the Mifflin St Jeor is probably the best to use. An alternative to the BMR formulas is to simply follow the commonly suggested minimal numbers of 1,to-1, calories for women and 1,to-1, calories for men.

These numbers, however, provide estimates at best because the macronutrient composition of a diet e. The sensation of hunger is another viable option to use as a guide, but the sensation of hunger is considered plastic i. Regardless, the hunger scale can help you gain a sense of whether you are providing adequate food calories to your body to avoid starvation — in other words, the opportunity to listen to your body.

Ideally , you would spend your waking hours between hunger scores of 4-and Lastly, take the time to understand some basic differences between hunger and appetite which are outlined below:.

While RMR is an important component of TDEE, an accurate measurement remains elusive for many. Subsequently, we resort to mathematical formulas, but considering their potential errors, the values determined should always be considered a general estimate rather than an accurate value.

Given this, there may also be value in including other methods as a guide to avoiding starvation.
