1. What is This Calorie Calculator?

This calculator estimates the daily calorie needs for men over 50 who want to lose weight. It's based on the Mifflin-St Jeor equation with an adjustment for weight loss in older men.

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 50+)
• \( activity\_factor \) — Multiplier for physical activity level
• 300 — Calorie reduction for weight loss in older men

Explanation: The equation calculates basal metabolic rate (BMR), adjusts for activity level, then subtracts 300 calories for safe weight loss in men over 50.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation helps create an effective weight loss plan while maintaining muscle mass and energy levels, which is especially important for men over 50.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age (must be 50+), and select your activity level. For best results, combine this calorie target with strength training and balanced nutrition.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 300 calories specifically?
A: This creates a modest deficit for gradual weight loss (about 0.3kg/week), which is safer and more sustainable for men over 50.

Q2: Should I eat fewer calories for faster weight loss?
A: Not recommended. Larger deficits can lead to muscle loss and metabolic slowdown, especially in older adults.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual needs may vary by ±200 calories. Adjust based on your results.

Q4: What if I'm very overweight?
A: The equation works well for most men. If BMI > 35, consult a dietitian for personalized advice.

Q5: Should I change my calories as I lose weight?
A: Yes, recalculate every 5-10kg lost, as your calorie needs will decrease with lower body weight.
