What Is Resting Metabolic Rate?
Resting Metabolic Rate (RMR) is the amount of energy your body expends when you’re not active. It indicates how many calories you consume when sitting without moving. You need to be aware of your RMR to be at your metabolic best.
Definition and Importance
Your RMR is the largest component of how many calories you expend every day, 60% to 75%. Knowing your RMR allows you to determine how many calories you require daily. If your RMR is high, you expend more calories, which aids in weight loss.
Knowledge of RMR is significant as it allows you:
To know how many calories you require each day
To plan your diet more effectively
Set achievable weight loss or gain goals
RMR vs. BMR: Understanding the Difference
Even though people often mix them up, RMR and Basal Metabolic Rate (BMR) are different. BMR is about the energy you use when you’re completely still and fasting, usually in a lab. RMR, however, is about your energy use when you’re resting normally.
The main differences are:
RMR is easier to measure and estimate
BMR needs a more controlled setting
RMR is better for everyday calorie requirements
The Science Behind Your Metabolism
Metabolism is how our body converts food into energy and the bits we require to develop and repair things. It’s a complicated system that keeps us alive. Understanding how it works can better inform us about our health.
How Your Body Burns Calories at Rest
Even when we’re not moving, our bodies still burn calories. This is called resting energy expenditure. It’s the biggest part of our daily energy use. Things like age, gender, and body type affect how many calories we burn at rest.
The resting metabolic rate (RMR) shows how many calories we burn at rest. It’s key to figuring out how many calories we need every day.
Metabolic Processes Explained
Metabolic processes are the ways in which our bodies break down and synthesize molecules in order to live. There are two broad categories: catabolism and anabolism. Catabolism degrades molecules in order to obtain energy. Anabolism constructs molecules from simpler substances, employing energy.
Cellular Energy Production
In the cell, energy is derived from the degradation of glucose. This produces ATP, the cell’s source of energy. This process is critical to all living cells.
Organ System Energy Requirements
Different organ systems require varying levels of energy. For instance, the brain and the liver consume a great amount of energy. This information assists us in determining our calculation of metabolic rate and energy requirements.
Factors That Affect Your Resting Metabolic Rate
Numerous factors can vary the manner in which your body consumes calories while you are at rest. Understanding these can assist you in selecting healthier foods and exercises.

Age and Gender
Age and sex impact your resting metabolic rate. Your RMR decreases as you age due to less muscle and less activity. Men tend to have a higher RMR than women because they have more muscle.
Body Composition and Muscle Mass
Your muscle composition, in particular, has a significant impact on your RMR. Muscle expends calories more than fat, even when you are at rest. Thus, individuals with more muscle have a higher RMR.
Hormonal Factors
Your RMR also depends a lot on hormonal factors. Thyroid hormones, for instance, determine how rapidly your metabolism is. If your thyroid is sluggish (hypothyroidism), your RMR decreases. If it’s overactive (hyperthyroidism), your RMR increases.
Genetics and Family History
Genetics and family history can also influence your RMR. You may get a faster or slower metabolism from your family. Although you can’t do anything about your genes, having this knowledge can inform you to plan your diet and exercise more appropriately.

Common RMR Calculation Formulas Explained
There are a number of formulas to calculate RMR, with each having its advantages and applications. These formulas assist in determining how much energy an individual requires daily. They are employed in medical environments as well as fitness regimens.
Mifflin-St Jeor Equation
The Mifflin-St Jeor formula is found to be highly accurate when it comes to determining RMR. It considers the individual’s sex, age, weight, and height. Men’s formula is: RMR (men) = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5. For women, the formula is: RMR (women) = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161. It’s used because it’s simple to use and easy to rely on.
Harris-Benedict Equation
The Harris-Benedict equation is another reliable formula for determining RMR. It considers the same variables as the Mifflin-St Jeor formula but with alternative figures. For males, it’s: RMR (men) = 66 + (6.2 x weight in lbs) + (12.7 x height in inches) – (6.8 x age in years). For females, it’s: RMR (women) = 655 + (4.35 x weight in lbs) + (4.7 x height in inches) – (4.7 x age in years). Although used, it is not quite as accurate as the Mifflin-St Jeor formula.
Katch-McArdle Formula
The Katch-McArdle formula is unique in that it incorporates lean body mass (LBM) in its calculation: RMR = 370 + (21.6 x LBM in kg). This is ideal for athletes or individuals with a great deal of muscle mass. It provides a more accurate reading by considering active tissue.
Every formula has its own advantages and disadvantages. The appropriate one varies on the information you have and the individual needs of the person or situation.
Knowing Your Total Daily Energy Expenditure
Total Daily Energy Expenditure, or TDEE, refers to the total calories your body expends on a daily basis. It’s important to know your daily energy expenditure. It’s calculated by your Resting Metabolic Rate (RMR) and activity level.
Activity Multipliers Explained
Activity multipliers vary your RMR for your workouts and daily activities. They are sedentary through very active. This reflects varying degrees of physical activity.
Sedentary vs. Active Lifestyles
Being sedentary entails little to no physical exercise, with a multiplier of approximately 1.2. An active lifestyle with frequent physical exercise has multipliers ranging between 1.55 and 1.9 or higher. This varies depending on the intensity and frequency of exercise.
Exercise Intensity Considerations
Exercise intensity greatly influences your TDEE. Moderate exercise such as walking or cycling boosts energy expenditure. High-intensity exercises like running or HIIT (High-Intensity Interval Training) increase it even further.
Calculating TDEE from RMR
To calculate your TDEE, multiply your RMR by an activity factor. For instance, if your RMR is 1,800 calories and you are moderately active, your TDEE is 2,790 calories. According to a study, “The Harris-Benedict equation and the Mifflin-St Jeor equation are employed to estimate RMR. Next, modify it with activity multipliers to estimate TDEE.”
“Accurate estimation of TDEE is crucial for creating effective training and nutrition plans.”
– Journal of Nutrition and Metabolism
Knowing your TDEE is vital in controlling your weight and fitness targets. With an accurate calculation, you can alter your diet as well as your training to suit your needs.
Applying RMR in Controlling Weight
Resting Metabolic Rate is instrumental in weight management. It’s a fundamental component of weight regulation. Being able to utilize your RMR can assist you in achieving your weight objectives. This entails losing weight, adding muscle, or maintaining your present weight.
Creating a Caloric Deficit for Weight Loss
To shed weight, you must consume fewer calories than you expend. Your RMR assists in determining how many calories to reduce. Aiming for a 500-calorie deficit per day may result in losing 1 pound weekly.

Caloric Surplus for Muscle Gain
If you want to build muscle, you have to consume more calories than you expend. Your RMR indicates the foundation calories for muscle building. Increasing 250-500 calories over your maintenance level aids in building muscle with strength training.
Keeping Weight with RMR Awareness
For those attempting to stay at their weight, having your RMR is important. It assists in discovering the appropriate caloric consumption to preserve your weight. By balancing what you eat and how much energy you burn, you can prevent weight alterations.
Myths Surrounding Metabolism
Metabolism is a complicated phenomenon, and there are plenty of myths around it. Awareness of the facts regarding metabolism is important for making good decisions regarding diet, exercise, and lifestyle.
Busting Popular Misconceptions
Some believe a higher metabolism is always beneficial. But it is not always. Elevated metabolic rate can facilitate weight loss but may also leave you hungrier and cause nutrient deficiencies if not controlled properly.
Another myth is that foods or supplements can significantly increase metabolism. Although some foods may have some effect on metabolic rate, this is generally minimal and temporary.
Common Metabolism Myths:
Myth: Under-eating slows metabolic rate.
Myth: Some foods can have a huge effect on metabolic rate.
Myth: Metabolism declines dramatically with age.

How to Increase Your Resting Metabolic Rate Naturally
Increasing your resting metabolic rate (RMR) naturally is achievable. You can accomplish it through combining strength training, nutritious eating, and adequate rest. These measures can enhance your metabolism and well-being.
Building Muscle Through Strength Training
Regular strength training is a top way to boost your RMR. Building muscle means your body burns more calories even when you’re not moving. Try exercises like squats, deadlifts, and bench presses to grow muscle. Make sure to do strength training two to three times a week.
Nutrition Strategies for Metabolic Health
Healthy eating is fundamental for your metabolic health. Consume plenty of protein from lean meats, fish, and legumes to gain muscle. In addition, include veggies, whole grains, and healthy fats in your diet. A well-known nutritionist once said,
“The key to a healthy metabolism is a balanced diet that supports your body’s needs.
Getting enough sleep and rest is crucial for a healthy metabolism. Make sure to sleep 7-9 hours each night to help your body heal. Bad sleep can mess with hormones, slowing down your metabolism. So, don’t forget to rest well to boost your RMR.
Tracking Changes in Your Metabolic Rate Over Time
With the change in your lifestyle and body, it’s important to monitor your resting metabolic rate (RMR). Your RMR is affected by hormones, muscle, and age. Monitoring this change will help you adjust your diet and exercise to meet your needs.
How Often to Recalculate Your RMR
How often to reset your RMR is up to you and depends on your goals and changes in your body. For most, it’s every 6-12 weeks. But, if you’re exercising hard or losing weight quickly, you may need to reset more often, such as every 4-6 weeks.
Adjusting Your Diet and Exercise Based on Changes
Once you have updated your RMR, you can modify your eating and exercise. If your RMR increases with muscle gain, you may require more calories. But if it decreases, perhaps due to aging or muscle loss, you may eat less or exercise more to maintain the same weight.
When to Consult a Professional About Your Metabolism
Knowing when to see a doctor about your metabolism is key. Metabolic health is complex. Some signs mean you need a professional’s help.
Signs of Metabolic Issues
Some symptoms point to metabolic problems. These include unexplained weight changes, constant tiredness, and trouble with blood sugar. If you notice these, getting medical advice is important.
