    Let’s explore how BMI works and how this tool helps you make smarter health decisions.

    ⚖️ What Is BMI?

    Body Mass Index (BMI) is a quick way to measure body fat based on your height and weight.
    It gives you an idea of whether you are underweight, healthy, overweight, or obese — helping you plan your diet and fitness goals better.

    🧠 The BMI Formula

    Depending on your measurement system, BMI can be calculated using one of the following formulas:

    Metric Formula:

    BMI = Weight (kg) / Height (m)2

    US Formula:

    BMI = {Weight (lb) / Height (in)2} × 703

    Example:
    If you weigh 70 kg and are 1.75 m tall, your BMI = 70 / (1.75 × 1.75) = 22.9 (Normal)

    🧩 BMI Categories and Meaning

    🧘‍♀️ Limitations of BMI

    While BMI is a great starting point, it doesn’t consider everything.

    ⚠️ What It Doesn’t Include:

    • Muscle vs. fat mass differences
    • Bone density
    • Gender-specific variations
    • Age-related body composition

    External Reference: According to research by the World Health Organization (WHO), BMI should be used along with waist measurements and lifestyle factors for a complete health picture.

    🥗 How to Maintain a Healthy BMI

    Staying within a healthy BMI range involves balanced nutrition, regular exercise, and good habits.

    ✅ Proven Tips:

    • Eat more whole foods (fruits, veggies, lean proteins).
    • Limit processed sugars and junk food.
    • Exercise at least 30 minutes daily.
    • Sleep 7–8 hours every night.
    • Track your progress using the BMI Calculator regularly.

    📊 BMI for Men and Women

    While the BMI formula is the same for everyone, men and women store body fat differently.

    • Men: More muscle, less fat → slightly higher BMI may still be healthy.
    • Women: Naturally higher fat percentage → BMI might appear higher even with balanced health.

    That’s why ToolsNode’s BMI calculator includes gender input for more accurate estimates.

    👶 BMI for Children and Teens

    BMI for children (ages 2–19) uses percentiles based on age and sex, not fixed ranges like adults.

    • Below 5th percentile → Underweight
    • 5th–85th percentile → Healthy weight
    • 85th–95th percentile → Overweight
    • Above 95th percentile → Obese

    (For accuracy, consult a pediatrician.)
