What is BMI?

Body Mass Index (BMI) is a simple measure to estimate body fat using your height and weight. It helps you understand if your weight is in a healthy range. BMI can indicate if you are:

1. Underweight
2. Normal / Healthy weight
3. Overweight
4. Obese

BMI is widely used by doctors and health professionals as a quick screening tool.

How to Calculate BMI

1. Take your weight in kilograms (kg)
2. Take your height in meters (m)
3. Use the formula: BMI = weight / (height × height) or kg/m²
4. Example: If you weigh 70 kg and are 1.75 m tall → BMI = 70 / (1.75 × 1.75) ≈ 22.9

BMI Categories

1. Below 18.5: Underweight
2. 18.5 – 24.9: Normal / Healthy weight
3. 25 – 29.9: Overweight
4. 30 and above: Obese
5. These ranges help identify potential health risks related to weight.

Why BMI Matters

1. Gives a quick estimate of body fat and overall health risk
2. Helps track weight changes over time
3. Supports planning for diet, exercise, or medical advice
4. Acts as an early warning for potential obesity-related diseases
5. Note: BMI is a general guide and may not account for muscle mass, bone density, or body composition

Tips to Maintain a Healthy BMI

2. Engage in regular physical activity like walking, running, or strength training
3. Monitor your weight regularly to stay within a healthy range
