BMR Calculator
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body requires to perform basic functions such as breathing, circulating blood, and cell production while at rest. Understanding your BMR helps you determine how many calories you should consume daily to maintain or adjust your weight based on your activity level.
Why is Knowing Your BMR Important?
Knowing your BMR allows you to understand how much energy your body needs at rest. This calculation is essential for people looking to manage their weight, whether it's through weight loss, maintenance, or muscle gain. Additionally, it serves as the foundation for calculating your daily calorie needs, which are influenced by your level of physical activity.
How to Use the BMR Calculator
This BMR calculator is designed to give you a personalized estimate of your daily calorie requirements based on your:
- Gender: Males and females have different metabolic rates due to physiological differences.
- Age: As you age, your metabolism slows down, requiring fewer calories.
- Weight: Heavier individuals need more energy to sustain bodily functions.
- Height: Taller individuals also require more energy to maintain basic bodily functions.
- Activity Level: Your BMR is multiplied by a factor based on your activity level to determine how many calories you need to sustain your energy expenditure.
How Does the BMR Formula Work?
There are two primary formulas used for calculating BMR: the Harris-Benedict Equation and the Mifflin-St Jeor Equation. This calculator uses the more recent Mifflin-St Jeor Equation for its accuracy and relevance.
For men: BMR = 88.36 + (13.4 × weight in kg) + (4.8 × height in cm) – (5.7 × age in years)
For women: BMR = 447.6 + (9.2 × weight in kg) + (3.1 × height in cm) – (4.3 × age in years)
