1. What is This Calorie Calculator?

This calculator estimates the daily calorie needs for men over 70 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 70 or older)
• \( activity\_factor \) — Multiplier based on physical activity level
• -300 — Calorie reduction for weight loss in older men

Explanation: The equation accounts for basal metabolic rate, physical activity, and the reduced calorie needs for weight loss in older men.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for healthy weight loss in older men, helping to maintain muscle mass while losing fat.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age (must be 70+), and select your activity level. The result shows recommended daily calories for gradual weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 300 calories?
A: This creates a moderate calorie deficit for safe weight loss in older men, helping preserve muscle mass.

Q2: How accurate is this for men over 80?
A: The equation works well up to age 90, but individual variations increase with extreme age.

Q3: Should I eat exactly these calories?
A: Use this as a starting point and adjust based on your weight loss progress and energy levels.

Q4: What if I have medical conditions?
A: Consult a doctor or dietitian before making significant dietary changes, especially with diabetes or heart disease.

Q5: How much protein should I eat?
A: Older men should aim for 1.0-1.2g protein per kg of body weight to maintain muscle during weight loss.
