1. What is the Calorie Maintenance Equation?

The calorie maintenance equation estimates the number of calories a man over 60 needs to consume daily to maintain his current weight, based on his weight, height, age, and activity level.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years (must be 60 or older)
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The equation accounts for basal metabolic rate (BMR) adjusted by physical activity level to estimate total daily energy expenditure.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation helps older men maintain a healthy weight, prevent muscle loss, and support overall health as metabolism changes with age.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age (60+ years), and select your typical activity level. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is this equation specific to men over 60?
A: Metabolism changes with age and differs by sex. This equation is tailored for older men's metabolic rates.

Q2: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Consider it a starting point and adjust based on results.

Q3: Should I use this if I want to lose weight?
A: For weight loss, consume 300-500 fewer calories than the maintenance value calculated here.

Q4: How often should I recalculate my needs?
A: Recalculate whenever your weight changes by 5+ kg or your activity level changes significantly.

Q5: What if I'm very muscular or have high body fat?
A: The equation may be less accurate. Consider consulting a dietitian for personalized assessment.
