1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest. It represents the minimum energy required to keep your body functioning, including breathing, circulation, and cell production.

2. How Does the Calculator Work?

The calculator uses the BMR equation for men:

Where:

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

Explanation: This equation calculates the basal metabolic rate specifically for adult men, taking into account weight, height, and age factors that influence metabolic rate.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It helps determine your daily caloric needs and forms the foundation for calculating Total Daily Energy Expenditure (TDEE).

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid positive numbers. For accurate results, use recent measurements.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is the calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise. TDEE = BMR × activity level multiplier.

Q2: How often does BMR change?
A: BMR changes with weight fluctuations, aging, muscle mass changes, and hormonal factors. It's recommended to recalculate every few months or after significant weight changes.

Q3: Can I increase my BMR?
A: Yes, through building muscle mass (muscle burns more calories than fat), regular exercise, proper hydration, and adequate protein intake.

Q4: Is this equation accurate for all men?
A: While generally accurate for most adult men, individual variations in muscle mass, body composition, and metabolic health can affect actual BMR. For precise measurements, professional metabolic testing is recommended.

Q5: How should I use my BMR for weight loss?
A: For weight loss, create a moderate calorie deficit (typically 300-500 calories below your TDEE) while ensuring you don't eat below your BMR, as this can slow metabolism and cause muscle loss.
