What is BMI and Why Does It Matter?

BMI, or Body Mass Index, is a simple formula used to categorize a person’s weight as underweight, normal, overweight, or obese based on their height and weight. It provides a quick way to assess whether your body weight falls within a healthy range

‍

BMI Formula

BMI = Weight (kg) / Height (m²)

For example, if you weigh 70 kg and are 1.75 meters tall, your BMI would be:BMI = 70 / (1.75 x 1.75) = 22.86

Why should i check my BMI?

• Helps estimate your risk for health issues like diabetes, heart disease, and hypertension.
• A useful first step in setting fitness or weight goals.
• Widely recognized by health professionals.

BMI Categories and What They Mean

BMI ranges help classify your weight status. Here’s how to interpret your number:

BMI Ranges (BMI Index Chart)

• Underweight: BMI less than 18.5
• Normal weight: BMI between 18.5–24.9
• Overweight: BMI between 25–29.9
• Obese: BMI 30 or higher

These ranges apply to most adults aged 18–65. However, factors like age, muscle mass, and gender can influence accuracy. For example, athletes with high muscle mass may fall into the “overweight” range even though they have low body fat.

‍Special Considerations – Age, Gender, and More

BMI isn’t one-size-fits-all. Here’s how it varies by demographic:

Women: Hormonal changes during menstruation, pregnancy, and menopause can affect body composition.

Men: Typically have more lean muscle mass, which may push their BMI higher.

Children and Teens: BMI is interpreted differently using age-specific growth charts.

Older Adults: Muscle loss can affect BMI accuracy. Sometimes body fat is underestimated.

Bioimpedance Analysis: For more accurate readings, methods like bioimpedance analysis or body fat index calculators can help, especially for athletes or elderly individuals.
