1. What is Weight Loss Planning?

Weight loss planning for men and women over 50 involves calculating appropriate calorie intake based on basal metabolic rate (BMR) and activity level, with a modest deficit for sustainable weight loss.

2. How Does the Calculator Work?

The calculator uses the following equation:

\[ Calories = BMR \times activity\_factor - 300 \]

Where:

\( BMR \) — Basal Metabolic Rate (kcal/day)
\( activity\_factor \) — Multiplier based on activity level (dimensionless)
300 — Moderate calorie deficit for sustainable weight loss (kcal/day)

BMR Calculation: Uses Mifflin-St Jeor Equation which differs by gender:

Male: \( BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) + 5 \)
Female: \( BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) - 161 \)

3. Importance of Calorie Calculation

Details: Accurate calorie calculation is crucial for healthy weight loss, especially for individuals over 50 where metabolic changes occur. A modest deficit helps preserve muscle mass while promoting fat loss.

4. Using the Calculator

Tips: Enter your gender, age (must be 50+), weight in kg, height in cm, and select your activity level. The calculator will show your BMR, activity factor, and recommended daily calories for weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 300 calories?
A: This creates a modest deficit for gradual weight loss (about 0.3kg/week) that's sustainable and preserves muscle mass.

Q2: Is this calculator only for people over 50?
A: While it works for any adult, the calculations are optimized for metabolic changes common after age 50.

Q3: How accurate is the BMR calculation?
A: The Mifflin-St Jeor Equation is about 90% accurate for most people, more precise than older equations.

Q4: Should I eat exactly these calories?
A: Use this as a starting point. Adjust based on your progress and consult a dietitian for personalized advice.

Q5: What if I'm losing weight too fast or not at all?
A: Adjust your calorie intake by 100-200 kcal as needed. Sustainable weight loss is typically 0.2-0.5kg per week.
