When it comes to understanding our body's energy expenditure, two terms often come up: Basal Metabolic Rate (BMR) and Resting Metabolic Rate (RMR). These measurements provide valuable insights into the number of calories our bodies burn at rest. However, there is often confusion surrounding the differences between BMR and RMR and which one to use for training goals. In this blog, we will explore BMR and RMR, decipher their distinctions, and discuss how they can contribute to achieving your training goals.
When it comes to understanding our body's energy expenditure, two terms often come up: Basal Metabolic Rate (BMR) and Resting Metabolic Rate (RMR).

However, there is often confusion surrounding the differences between BMR and RMR and which one to use for training goals. In this blog, we will explore BMR and RMR, decipher their distinctions, and discuss how they can contribute to achieving your training goals.
Understanding BMR and RMR
1. Basal Metabolic Rate (BMR):
Basal Metabolic Rate (BMR) is the number of calories your body needs to sustain basic physiological functions while at complete rest. These functions include breathing, circulation, cell production, and maintaining body temperature. BMR is typically measured in a controlled environment, after an overnight fast and with no physical or mental stimulation. BMR provides a baseline estimation of your minimum caloric needs.
2. Resting Metabolic Rate (RMR):
Resting Metabolic Rate (RMR) is similar to BMR and is often used interchangeably, but it accounts for a slightly broader range of conditions. RMR takes into account the same physiological functions but is measured in a more relaxed setting. It considers resting conditions where an individual is awake but in a physically and mentally relaxed state. RMR is a practical alternative to BMR as it reflects the body's energy needs in a more realistic and attainable context.
Which One to Use?
The choice between BMR and RMR depends on the purpose and practicality of the measurement:
1. Research and Clinical Settings
BMR measurements are typically used in research or clinical settings where strict control over the testing environment is possible. These measurements are highly accurate but are less practical for everyday use.
2. Personal Training and Fitness Goals
For most individuals pursuing training goals, RMR is a more accessible and practical measurement. RMR provides a close estimate of the energy your body requires at rest and is often used as a starting point for designing nutrition and training plans.
Using BMR or RMR for Training Goals
While BMR and RMR are essential measurements, it's important to note that they alone won't directly impact your training goals. However, they provide valuable information that can guide your approach:
1. Caloric Intake and Weight Management
Both BMR and RMR provide insights into your baseline caloric needs. By understanding the energy your body requires at rest, you can establish an appropriate caloric intake for weight management. Consuming more calories than your BMR or RMR suggests can lead to weight gain, while consuming fewer calories can result in weight loss.
2. Nutrition Planning
BMR or RMR measurements can help design personalized nutrition plans. With the knowledge of your resting energy expenditure, you can adjust macronutrient ratios to meet specific goals, such as muscle gain or fat loss. Nutrition plans can be tailored to provide sufficient energy for workouts, promote recovery, and support overall performance.
3. Training Intensity and Goals
BMR or RMR can inform your training strategy by highlighting your body's energy requirements at rest. This knowledge can guide your decision-making regarding training intensity, duration, and recovery. Adjusting your training program based on your metabolic rate can help optimize energy utilization, enhance performance, and achieve specific fitness goals.
4. Monitoring Progress
Regularly reassessing your BMR or RMR throughout your training journey can help you monitor progress and make necessary adjustments. As your body composition changes and fitness levels improve, your metabolic rate may fluctuate. Monitoring these changes allows you to fine-tune your nutrition and training plans accordingly.
Conclusion
Understanding the distinctions between BMR and RMR is crucial for achieving your training goals effectively. While BMR represents the energy needed at complete rest, RMR provides a more realistic estimation of resting energy expenditure. RMR is typically more practical for everyday use, especially when designing personalized nutrition and training plans.
Utilizing BMR or RMR measurements can guide your caloric intake, inform nutrition planning, optimize training strategies, and monitor progress. However, it's important to remember that BMR or RMR alone won't directly determine the success of your training goals. They serve as valuable tools to enhance your understanding of your body's energy needs and create a framework for effective training and nutrition practices.
Consulting with a qualified professional, such as a registered dietitian or certified personal trainer, can help you interpret BMR or RMR measurements and design a comprehensive training plan tailored to your specific goals. By incorporating these measurements into your fitness journey, you can optimize your training and maximize your potential for success.
