1. What is the Forbes BMR Equation?

The Forbes BMR equation estimates Basal Metabolic Rate (BMR) from weight, height, and age. BMR represents the number of calories your body needs to perform basic life-sustaining functions at rest.

2. How Does the Calculator Work?

The calculator uses the Forbes BMR equation:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years

Explanation: This equation provides an estimate of the calories your body burns at complete rest to maintain vital functions.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for weight management, creating effective diet plans, and understanding your body's energy requirements for maintaining, losing, or gaining weight.

4. Using the Calculator

Tips: Enter weight in kilograms, height in centimeters, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to perform basic functions like breathing, circulation, and cell production while at complete rest.

Q2: How accurate is the Forbes BMR equation?
A: While no equation is 100% accurate for everyone, the Forbes equation provides a good estimate for most adults. Individual variations may occur.

Q3: Should I use BMR or TDEE for diet planning?
A: BMR gives your baseline calories at rest. For diet planning, you should calculate your Total Daily Energy Expenditure (TDEE) by multiplying BMR by your activity level.

Q4: How often does BMR change?
A: BMR changes with age, weight fluctuations, muscle mass changes, and hormonal factors. It's recommended to recalculate periodically.

Q5: Can I increase my BMR?
A: Yes, through regular exercise, building muscle mass, proper nutrition, and adequate sleep can help increase your metabolic rate.
