An online BMR calculator allows you to calculate basal metabolic rate and calories need online. Mifflin st jeor equation calculator finds how many calories consume while your body is at rest. Enter the required parameters and the tool will instantly show calculations.
What Is BMR?
BMR stands for the basal metabolic rate which is the minimum amount of energy our body requires to stay alive. BMR is the major component of a person’s total calorie needs.
BMR Formula:
Everybody requires a little amount of energy for their survival. As we know energy level varies from person to person. The formulas that are used with respect to variations of resting metabolic rate by the bmr weight loss calculator are as follows;
Mifflin st jeor:
This BMR calculator with activity level uses Mifflin st jeor equation which is the most accurate BMR equation used to calculate the basal metabolic rate (BMR).
For men = (10 * weight in kg) + (6.25 * height in cm) - (5 * age in years) + 5
For women = (10 * weight in kg) + (6.25 * height in cm) - (5 * age in years) - 161
Revised haris benedict:
For men = (13.397 * weight) + (4.799 * height) - (5.677 * age) + 88.362
For women = (9.247 * weight) + (3.098 * height) - (4.330 * age) + 447.593

BMR = 370 + 21.6(1-body fat) * lean body mass
BMR does not include the calories that your burn daily from normal activities or exercise. In this case, you can use our TDEE calculator which will help you to estimate the energy that you use by assuming different types of exercises.
How To Estimate BMR?
BMR is resting calorie burn. Let's move on to calculate a basal metabolic rate that demonstrates the purpose of the BMR calculator to lose weight in the best way. Take a quick look at the example below.
Example:
Suppose that a 40 years old person whose weight is 170 pounds and he is 67 inches tall. Calculate their basal metabolic rate.
Solution:
Weight = 170 pounds
Height = 67 inches
Age = 40 years
The basal metabolic rate calculator helps you to understand your body requirements and current status. It makes it easier for you to make adjustments in your life that will have a positive impact.
BMR Formula to evaluate calories consumption;
For men = 66.47 + (6.24 * weight in pounds) + (12.7 * height in inches) - (6.75 * age in years)
For women = 65.51 + (4.35 * weight in pounuds) + (4.7 * height in inches) - (4.7 * Age in years)
BMR = 66.47 + (6.24 * 170) + (12.7 * 67) - (6.75 * 40)
BMR = 66.47 + 1060.8 + 850.9 - 270
BMR = 1708.17
Actually, you are looking at these calories that you burn without any activity. If you want to estimate the number of calories that are needed each day to maintain weight then you can use our calorie calculator.

FAQs
Does Nutritional Status Influence BMR?
BMR is dependent on various factors like age, gender, body temperature, height, current weight, body composition, and nutritional status.
You should take the help of our macro calculator to estimate the number of nutrients and macronutrients.
What Is Metabolism?
The conversion of food into energy is the result of a chemical reaction that occurs in the body's cells. This is called metabolism.
What Is The Ideal BMR Value For Women?
BMR is directly proportional to the fat-free mass. For women, typically 1000 to 2000 calories burn to do basic functions. In the case of men, about 1600 to 1800 calories burn in normal activities.
What Is The Daily Life Example Of BMR?
When a body is at rest basal metabolic rate is a waste of energy at that time. Suppose that a car is at rest means that the car is still in parking. How much gas a car is consumed in parking? We should equivalent this to the BMR.
