What is BMI (Body Mass Index)?

BMI stands for Body Mass Index. It is a mathematical formula that uses your weight and height to determine whether you are underweight, normal weight, overweight, or obese.

BMI is commonly used by doctors, fitness trainers, and health professionals as a quick screening tool to assess body weight categories.

BMI Formula

BMI is calculated using the formula:

BMI = Weight (kg) ÷ Height (m²)

For example, if your weight is 70 kg and your height is 1.75 meters, your BMI would be calculated as:

70 ÷ (1.75 × 1.75) = 22.86

BMI Categories Explained

Underweight (BMI less than 18.5)

If your BMI is below 18.5, it means you are underweight. This may indicate that your body is not getting enough nutrients, and you may need to improve your diet.

Normal Weight (BMI 18.5 – 24.9)

This is considered the healthy range. People in this category usually have a balanced body weight and lower risk of health problems.

Overweight (BMI 25 – 29.9)

If your BMI falls in this range, it means you have excess body weight. This can increase the risk of diseases like diabetes and heart problems.

Obese (BMI 30 and above)

Obesity indicates high body fat, which can lead to serious health conditions. It is recommended to consult a doctor or fitness expert.
