Body Mass Index (BMI) is a simple and widely used method to estimate whether a person has a healthy body weight for their height. It is a quick screening tool used by health professionals to categorize individuals into different weight ranges and assess the risk of health problems related to underweight, overweight, or obesity.

🧮 How is BMI Calculated?

BMI is calculated using the following formula:

• Metric system:
  BMI = weight (kg) ÷ height² (m²)
• Imperial system:
  BMI = (weight in pounds × 703) ÷ height² (inches)

📊 BMI Categories:

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

🧠 Why is BMI Important?

BMI provides a quick estimate of body fat, which is helpful for assessing general health. A higher BMI is often associated with increased risk of conditions such as:

• Heart disease
• High blood pressure
• Type 2 diabetes
• Sleep apnea
• Certain cancers

However, it's important to note that BMI is not a perfect measurement. It doesn’t consider muscle mass, bone density, age, gender, or overall body composition. For example, athletes may have a high BMI due to muscle, not fat.

🧭 What to Do Based on Your BMI?

• If your BMI is in the normal range, continue maintaining a balanced diet and regular exercise.
• If your BMI is low (underweight), consult a healthcare provider to assess nutritional status and underlying issues.
• If your BMI is high (overweight or obese), consider a healthy weight-loss plan through diet, exercise, and possibly professional guidance.
