1. What is BMI?

BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult women. It's commonly used in Weight Watchers programs to assess weight categories.

2. How Does the Calculator Work?

The calculator uses the BMI equation:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The equation calculates body mass per unit of height squared to estimate body fatness.

3. Importance of BMI Calculation

Details: BMI helps identify weight categories that may lead to health problems. It's a simple screening tool for weight classification in Weight Watchers programs.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are the BMI categories for women?
A: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), Obesity (≥30).

Q2: How accurate is BMI for women?
A: BMI is a useful screening tool but doesn't directly measure body fat. Athletic women may have higher BMI due to muscle mass.

Q3: Should BMI be interpreted differently for women?
A: Women typically have more body fat than men at the same BMI. However, the same categories apply to both genders.

Q4: What's the ideal BMI for women in Weight Watchers?
A: Weight Watchers generally aims for a BMI in the normal range (18.5-24.9).

Q5: Are there limitations to BMI?
A: BMI doesn't account for muscle mass, bone density, or fat distribution. It should be used alongside other measurements.
