1. What Is This Calculator For?

This calculator estimates the daily calorie needs for women over 50 who want to lose weight. It calculates your Basal Metabolic Rate (BMR), Total Daily Energy Expenditure (TDEE), and suggests a calorie intake for weight loss based on your chosen deficit.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years (must be 50 or older)
• \( activity\ factor \) — Multiplier based on activity level
• \( deficit \) — Calorie deficit for weight loss (typically 500 kcal/day)

Explanation: BMR is the calories your body needs at complete rest. TDEE accounts for your activity level. The deficit creates weight loss.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation is crucial for healthy weight loss, especially for women over 50 when metabolism slows down. It helps prevent muscle loss and ensures adequate nutrition.

4. Using the Calculator

Tips: Enter your current weight, height, and age (must be 50+). Select your activity level honestly. A 500 kcal/day deficit typically results in about 0.5 kg weight loss per week.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculator specific to women over 50?
A: Metabolism changes with age and gender. Women over 50 typically have lower calorie needs than younger women due to hormonal changes and decreased muscle mass.

Q2: What's a safe calorie deficit?
A: 250-500 kcal/day is generally safe. Don't go below 1200 kcal/day without medical supervision.

Q3: How often should I recalculate?
A: Recalculate every 5-10 kg of weight loss or if your activity level changes significantly.

Q4: Why include activity factor?
A: More active people burn more calories and can eat more while still maintaining a deficit.

Q5: What if I'm not losing weight?
A: You may need to adjust your calorie intake, increase activity, or consult a doctor to rule out medical issues.
