1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. For women over 55, this calculation helps determine appropriate calorie intake for weight loss.

2. How Does the Calculator Work?

The calculator uses the BMR equation for women:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years (must be 55 or older)

Explanation: This equation estimates the calories needed to maintain basic bodily functions without any additional activity.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating an effective weight loss plan. It serves as the foundation for determining your daily calorie needs when combined with activity level.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age (must be 55+). For weight loss, aim for a calorie intake slightly below your BMR plus activity calories.

5. Frequently Asked Questions (FAQ)

Q1: Why is this equation specific to women over 55?
A: Metabolism changes with age and gender. This equation accounts for the lower metabolic rate typically seen in postmenopausal women.

Q2: How should I use my BMR for weight loss?
A: Start by eating at your BMR level and add light exercise. For faster weight loss, create a modest deficit (200-300 calories below maintenance).

Q3: Does BMR change with weight loss?
A: Yes, as you lose weight your BMR decreases. Recalculate periodically to adjust your calorie intake.

Q4: What factors affect BMR besides age?
A: Muscle mass, hormones, genetics, and body composition all influence BMR. Muscle tissue burns more calories than fat at rest.

Q5: Should I eat below my BMR?
A: It's generally not recommended to eat significantly below your BMR as this can slow metabolism and cause nutrient deficiencies.
