1. What is BMR (Men Formula)?

The BMR (Basal Metabolic Rate) Men Formula estimates the number of calories your body needs to maintain basic physiological functions at rest. This version is specifically calibrated for adult males.

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: The equation accounts for the energy needed to maintain basic bodily functions based on body size and age.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in creating personalized diet plans, whether for weight loss, maintenance, or gain. It's the foundation for calculating total daily energy expenditure.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120). For accurate results, measure weight in the morning before eating.

5. Frequently Asked Questions (FAQ)

Q1: How does BMR differ for women?
A: The women's formula is: BMR = 10 × weight + 6.25 × height - 5 × age - 161. Women generally have lower BMR due to higher body fat percentage.

Q2: What are typical BMR values for men?
A: Average BMR for adult men ranges from 1600-2000 kcal/day, but varies significantly with body size and composition.

Q3: How accurate is this formula?
A: It provides a reasonable estimate but may be ±10% off for individuals with very high or low muscle mass.

Q4: Should I use this for weight loss planning?
A: Yes, but remember to multiply BMR by activity factor to get total daily energy needs before creating a calorie deficit.

Q5: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Very muscular individuals may have higher BMR than the formula predicts.
