Daily Caloric Needs by Activity Level

Welcome to the RMR Calculator, a highly precise tool to know how many calories your body burns while completely at rest. Understanding your Resting Metabolic Rate -(RMR) is really important for effective weight management, fat loss, or gaining muscle.

This Resting Metabolic Rate Calculator utilizes research-tested formulas such as 'Mifflin-St Jeor', 'Harris-Benedict', 'Katch-McArdle', and 'Cunningham' providing you the most accurate outcome given your 'age', 'gender', 'height', and 'weight'.

What Is Resting Metabolic Rate (RMR)?

Resting Metabolic Rate - (RMR) defines the calorie needs of your body to conduct necessary life functions - such as breathing, circulating blood, body temperature maintenance, and cell repair when the body is completely at rest.

In simple terms, it's the most minimal amount of calories your body burns for you to live.

Our RMR Calculator will help you work out your RMR right away so you'll understand your baseline caloric need before adding in any physical activity or exercise.

How Our RMR Calculator Works

Our Resting Metabolic Rate Calculator is predicated on sound science. It follows the Mifflin-St Jeor Equation (preferred) - the most trusted equation accepted by the nutrition and health community.

You simply need to:

1.
Enter your age, gender, height, and weight.
2.
Select a method of calculation (Mifflin-St Jeor, Harris-Benedict, etc.)
3.
Optionally, you can input your body fat percentage for additional accuracy.

In just a few seconds, you will have your RMR(Resting Metabolic Rate), - which represents the total calories that your body burns in a 24-hour period while at rest. You will also have the ability to compare results, using different equations, while exploring your daily caloric needs based on your level of activity.

Why You Should Know Your RMR

Understanding your RMR is a game-changer for anyone looking to:

Lose Weight: Eating fewer calories than your RMR plus your activity level.
Gain Muscle: Eating just above your daily calorie needs calculated based on your RMR.
Maintain Weight: Matching your calorie intake with total energy expenditure.

When you calculate your RMR, it gives you a sense of your metabolism and offers you an opportunity to make better nutritional, and fitness, choices. It doesn't matter if your an athlete, an exercise enthusiast, or just starting your health journey, our RMR Calculator helps keep you on track.

RMR vs. BMR:- What is the difference?

Many people confuse RMR(Resting Metabolic Rate) with BMR(Basal Metabolic Rate). Here is the difference:

BMR is measured under very strict conditions (complete rest, fasting, no physical activity).
RMR is slightly higher because it includes basic daily activities like sitting, eating, or minor movements.

Our Resting Metabolic Rate RMR Calculator gives you a more realistic estimation that reflects your actual calorie needs in daily life.

Equations Used in the RMR Calculator

Our tool lets you compare results from multiple scientific methods:

Mifflin-St Jeor (Recommended): - Recognized as the gold standard for the general population, includes the variables of age, weight, height, and gender
Harris-Benedict: - Original RMR equation, has been found to be slightly less accurate than Mifflin-St Jeor
Katch-McArdle: - Most accurate estimate when using body fat %. The best estimate for someone who weight trains
Cunningham: - Accurate for athletes or individuals with known lean body mass

The variations provided make it easy to accurately calculate your RMR, regardless of your goal.

FAQs

An RMR calculates an estimate of how many calories your body burns while at rest, to help you understandsome physiology of metabolism and caloric requirements for the day.

You can, calculate your RMR using formulas like 'Mifflin-St Jeor', 'Harris-Benedict', or 'Katch-McArdle'. Simply input your personal data into our Resting Metabolic Rate Calculator for quick results.

Knowing your RMR helps you tailor your diet and fitness plan for better weight management, improved energy, and efficient metabolism tracking.

No - RMR(Resting Metabolic Rate) includes minimal daily activities, while BMR(Basal Metabolic Rate) measures energy used at complete rest in a controlled setting.

You can calculate your RMR every few months, especially if your 'weight', 'fitness level', or 'lifestyle' changes significantly.

Yes - your Resting Metabolic Rate can vary with 'age', 'body composition', 'muscle mass', and 'hormone levels'. Regularly using an RMR Calculator helps track those changes.
