Calculate your Basal Metabolic Rate (BMR) by entering
Your BMR is _ calories/day.
What is BMR?
Basal Metabolic Rate (BMR) represents the minimum amount of energy (in calories) that your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at rest. It is an essential metric for understanding your body's energy requirements, helping you better manage your diet, weight, and overall health.
How to Calculate BMR
To calculate BMR, the most commonly used formula is the Harris-Benedict equation, which takes into account factors such as age, gender, weight, and height. There are two versions of the Harris-Benedict equation—one for men and another for women:

Example Calculation
Let’s say a 30-year-old man weighs 70 kg, is 1.75 meters tall (175 cm), and wants to calculate his BMR. Using the Harris-Benedict equation:
Why is BMR Important?
Knowing your BMR helps you make informed decisions about your nutrition and exercise regimen, particularly if you're trying to lose, gain, or maintain weight. If you consume fewer calories than your TDEE, you’ll likely lose weight. If you consume more, you’ll likely gain weight.
Limitations of BMR
- Doesn't account for muscle mass:BMR calculations don't directly consider lean muscle mass, which can affect calorie needs.
- Age and metabolism changes:As you age, your metabolism naturally slows down, and your BMR decreases.
- General estimate:While the Harris-Benedict equation is widely used, it provides only an estimate of your daily calorie needs.
