1. What Is This Calorie Calculator?

This calculator estimates the daily calorie needs for men over 40 who want to lose weight, based on the Mifflin-St Jeor equation with a 500-calorie deficit for weight loss.

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 40 or older)
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The equation calculates your basal metabolic rate (BMR), adjusts for activity level, then subtracts 500 calories to create a weight loss deficit.

3. Importance Of Calorie Calculation

Details: Accurate calorie estimation is crucial for healthy weight loss, especially for men over 40 when metabolism naturally slows down.

4. Using The Calculator

Tips: Enter your current weight in kg, height in cm, age (must be 40+), and select your activity level. The result shows daily calories for steady weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit typically results in about 1 pound (0.45 kg) of weight loss per week, which is a safe and sustainable rate.

Q2: Is this calculator only for men over 40?
A: Yes, the calculation is specifically adjusted for the metabolic changes that occur in men after age 40.

Q3: How accurate is this calculation?
A: It provides a good estimate, but individual variations in metabolism may require adjustments based on actual results.

Q4: Should I eat fewer calories for faster weight loss?
A: Not recommended. Very low calorie diets can lead to muscle loss and metabolic slowdown, especially in older men.

Q5: How often should I recalculate my needs?
A: Recalculate every 5-10 kg of weight loss or if your activity level changes significantly.
