Calculate Your BMR

Male Female

Definition of BMR (Basal Metabolic Rate)

BMR refers to the basal metabolic rate, the amount of energy a person’s body needs to function at rest.

For an accurate BMR, you need to use our BMR calculator. It is important to know your BMR to set realistic health and fitness goals

Knowing your BMR helps you determine how many calories you need daily based on your activity level, weight, and goals for gaining or losing weight.

BMR measures the energy required for digestion, brain activity, and other bodily functions that don’t involve physical activity, such as increasing muscle mass or rebuilding tissue.

With our accurate BMR calculator, you can easily create an effective meal plan without constantly guessing what you should eat.

This important figure can also help you track your progress in improving general health or getting into shape. Understanding your BMR is the first step toward achieving your goals!

Importance of BMR in weight loss and overall health

Understanding and tracking your BMR is important for weight management and overall health because it can also help you determine how many calories you need to consume to maintain, lose, or gain weight.

This is important because the number of calories you consume must be balanced with the number of calories you burn through physical activity and daily life to maintain a healthy weight.

1. Your basal metabolic rate (BMR) is the number of calories your body burns at rest. Various factors, including your age, weight, and muscle mass, influence it.

Maintaining a healthy BMR is important for weight management and overall health.

2. A high BMR means that your body is able to burn more calories at rest, which can help with weight loss.

A low BMR, on the other hand, can make it difficult to lose weight or even maintain your current weight.

3. Maintaining a healthy BMR is also important for overall health. A high BMR has been linked with a lower risk of chronic diseases such as heart disease, diabetes, and obesity.

An increased BMR can also help improve mental health and cognitive function.

4. You can also do several things to increase your BMR, including exercise and eating a healthy diet.

Getting enough sleep and managing stress levels are also important for maintaining a healthy BMR.

5. If you are trying to lose or diet weight, you must consult a healthcare professional to determine the best plan for you.

This may include changing your diet and exercise routine, as well as taking medications or supplements.( Doctor required)

Accurate BMR Calculator Formula

Several formulas can be used to calculate the basal metabolic rate (BMR). Some of the most commonly used formulas include:

Harris-Benedict formula

This formula calculates BMR based on your weight, height, age, and gender.

The equation for men is BMR = 66 + (6.2 x weight in pounds) + (12.7 x height in inches) – (6.76 x age in years).

The equation for women is BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years).

Mifflin-St. Jeor formula

This formula is similar to the Harris-Benedict formula but is considered to be more accurate. 

The equation for men is BMR =( 10 x weight in kilograms(kg) + 6.25 x height in centimeters(cm) – 5 x age in years + 5). 

The equation for women is BMR = 10 x weight in kilograms(kg) + 6.25 x height in centimeters(cm) – 5 x age in years – 161.


McArdle formula is based on your weight and body fat percentage. It is used to calculate BMR in people who are leaner and have more muscle mass.

The equation is BMR = 370 + (21.6 x lean body mass in kilograms).

It’s important to note that these formulas are estimates and may not be accurate for everyone. Other factors that can affect BMR include your level of physical activity, your diet, and your overall health.

How to use a BMR calculator

  1. First enter your gender, age, weight, and height.
  2. After that, put your right weight in lbs and height in inches.
  3. Now click the “calculate BMR ” button . Boom! now you get the accurate BMR for your health.

Factors that affect BMR

Several factors can affect your basal metabolic rate, including:

Age: As you age, your metabolism tends to slow down. This is because you lose muscle mass and gain fat as you get older, which can decrease your basal metabolic rate.

Weight: Your BMR is directly related to your weight. Generally, people who weigh more have a higher BMR because they have more body mass to maintain.

Height: Your height can also affect your basal metabolic rate. Because they have more body mass to keep up with, taller people tend to have a higher BMR.

Gender: Due to having more muscle mass and less body fat, men tend to have a higher BMR than women.

Genetics: Your genetic makeup can also play a role in your BMR. Some people may have a naturally faster metabolism due to their genetic makeup.

Hormones: Hormonal imbalances or changes in hormone levels can affect your BMR. For example, thyroid hormones play a key role in metabolism, and people with hypothyroidism (an underactive thyroid gland) may have a lower BMR.

It’s important to note that these are just some factors that can affect BMR, and the relative impact of each element can vary from person to person. To get a more accurate estimate of your BMR, you can use a BMR calculator or consult a healthcare professional.

Wrap Up

Understanding and tracking your basal metabolic rate is an important step in any weight-management journey.

By taking into account our daily activities and lifestyle, BMR serves as a valuable indicator of how many calories our bodies need to perform at the highest level possible.

A BMR calculator can be used to help calculate the amount of calories needed for an individual based on their current lifestyle and activity levels.

Also, it’s important to keep a close eye on your energy output by keeping track of both what you eat and how much you move around.

Doing this will help you understand how many calories are being burned throughout the day, so that you can make healthier dietary choices and maintain or increase your current level of physical activity.
