BMR Calculator
Calculate your Basal Metabolic Rate (BMR) to understand the number of calories your body needs at rest.
Your BMR
How the BMR Calculator Works
Our BMR Calculator estimates your Basal Metabolic Rate, which is the number of calories your body needs to perform its most basic (basal) functions—like breathing, circulation, nutrient processing, and cell production—while at rest.
What Is BMR?
Basal Metabolic Rate (BMR) is the largest component of your total daily energy expenditure. Knowing your BMR can help you understand your body's energy needs and create a more effective diet and exercise plan.
How This Calculator Determines Your BMR
- Input Your Details: Enter your age, gender, height, and weight.
- BMR Calculation: The calculator uses the Mifflin-St Jeor equation to estimate your BMR:
- Men: 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) + 5
- Women: 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) - 161
Why Use a BMR Calculator?
Using a BMR calculator can help you:
- Understand Your Metabolism: Get a baseline understanding of your body's energy needs.
- Create a Calorie Target: Use your BMR as a starting point for determining your daily calorie needs based on your activity level and goals.
- Optimize Your Diet: Knowing your BMR can help you avoid eating too few calories, which can slow down your metabolism.
Frequently Asked Questions (FAQs)
1. What's the difference between BMR and RMR?
BMR (Basal Metabolic Rate) and RMR (Resting Metabolic Rate) are often used interchangeably, but they have slightly different meanings. BMR is the minimum number of calories required for basic functions at rest, while RMR is the number of calories your body burns while at rest. RMR is usually slightly higher than BMR.
2. Can I increase my BMR?
Yes. Building muscle mass is one of the most effective ways to increase your BMR. The more muscle you have, the more calories your body burns at rest.
