1. What is the Harris-Benedict Equation?

The Harris-Benedict Equation is a widely used formula to estimate basal metabolic rate (BMR) and total daily energy expenditure (TDEE). This version is specifically designed for men and provides an estimate of daily calorie needs based on weight, height, age, and activity level.

2. How Does the Calculator Work?

The calculator uses the Harris-Benedict equation for men:

\[ TDEE = (88.362 + (13.397 \times weight) + (4.799 \times height) - (5.677 \times age)) \times activity \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity \) — Activity level multiplier

Activity Level Multipliers:

Sedentary (little or no exercise): 1.2
Lightly active (light exercise/sports 1-3 days/week): 1.375
Moderately active (moderate exercise/sports 3-5 days/week): 1.55
Very active (hard exercise/sports 6-7 days a week): 1.725
Extra active (very hard exercise/sports & physical job): 1.9

3. Importance of TDEE Calculation

Details: Calculating TDEE is essential for weight management, whether your goal is weight loss, weight maintenance, or weight gain. It helps determine appropriate calorie intake for your specific needs and activity level.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid (weight > 0, height > 0, age between 1-120, activity level selected).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the Harris-Benedict equation?
A: The equation provides a good estimate for most people, but individual variations in metabolism may affect accuracy. It's best used as a starting point.

Q2: Should I use this equation if I'm very muscular or have high body fat?
A: The equation may be less accurate for extremely muscular individuals or those with very high body fat percentages, as it doesn't account for body composition.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly, your activity level changes, or every few months to account for metabolic changes.

Q4: Is this equation suitable for athletes?
A: While it can provide a baseline estimate, athletes with very high training volumes may need more precise calculations that account for their specific sport and training intensity.

Q5: Can I use this for weight loss planning?
A: Yes, subtract 500-1000 calories from your TDEE to create a calorie deficit for weight loss, aiming for 0.5-1 kg loss per week.
