1. What is This Calorie Calculator?

This calculator estimates the daily calorie intake needed for weight loss in men based on the Mifflin-St Jeor equation with a 500-calorie deficit, as commonly recommended on Reddit weight loss communities.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\_factor \) — Multiplier based on activity level
• 500 — Calorie deficit for weight loss

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

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for effective weight loss. A 500-calorie daily deficit typically results in about 1 pound (0.45 kg) of weight loss per week.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select your activity level. For best results, use accurate measurements and be honest about your activity level.
