BMR Calculator

The BMR is calculated using the Mifflin-St Jeor Equation, which is the most accurate formula for estimating BMR. Here are the steps:

Input Your Details:
- Gender: Select your gender (male or female).
- Age: Enter your age in years.
- Weight: Enter your weight in kilograms.
- Height: Enter your height in centimeters.
Calculation:
- For Men:BMR=(10×Weight)+(6.25×Height)−(5×Age)+5BMR=(10×Weight)+(6.25×Height)−(5×Age)+5
- For Women:BMR=(10×Weight)+(6.25×Height)−(5×Age)−161BMR=(10×Weight)+(6.25×Height)−(5×Age)−161
Result:
- The calculator will display your estimated BMR in calories per day.

What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions (like breathing, circulation, and cell production) at rest. It accounts for about 60-70% of your total daily energy expenditure.
Why Calculate BMR?
- Helps you understand your body’s energy needs.
- Serves as a starting point for creating a personalized diet plan.
- Useful for weight loss, weight gain, or weight maintenance goals.
Factors Affecting BMR:
- Age: BMR decreases with age.
- Gender: Men generally have a higher BMR than women due to higher muscle mass.
- Weight: Heavier individuals have a higher BMR.
- Height: Taller individuals have a higher BMR.
Interpreting Results:
- Your BMR is the number of calories you need to consume daily to maintain your current weight if you were at complete rest.
- To account for physical activity, multiply your BMR by an activity factor:
  - Sedentary (little or no exercise): BMR × 1.2
  - Lightly active (light exercise/sports 1-3 days/week): BMR × 1.375
  - Moderately active (moderate exercise/sports 3-5 days/week): BMR × 1.55
  - Very active (hard exercise/sports 6-7 days/week): BMR × 1.725
  - Super active (very hard exercise/physical job): BMR × 1.9
Limitations:
- The formula provides an estimate and may not account for individual variations like muscle mass or medical conditions.
- For precise measurements, consult a healthcare professional.
