Understanding Body Mass Index

Body Mass Index (BMI) is a widely used measure to categorize individuals based on their weight relative to their height. While not a direct measure of body fat, it serves as a useful screening tool for identifying potential weight-related health issues.

BMI Formula

BMI = Weight (kg) / Height (m)²

Health Risks by BMI Category

  • Underweight: Risk of malnutrition, osteoporosis, decreased immune function
  • Normal: Lower risk of weight-related health issues
  • Overweight: Increased risk of heart disease, high blood pressure
  • Obese: Higher risk of diabetes, heart disease, certain cancers

Tips for Maintaining Healthy Weight

Focus on balanced nutrition with plenty of fruits, vegetables, and whole grains. Aim for at least 150 minutes of moderate exercise per week. Stay hydrated, get adequate sleep, and manage stress. Small, sustainable changes are more effective than extreme diets.

Frequently Asked Questions

Is BMI accurate for everyone?
