📖 What is BMI?

Body Mass Index (BMI) is a widely used screening tool that measures body fat based on height and weight. It's calculated using the formula: BMI = weight (kg) / height (m)² for metric units, or BMI = (weight (lbs) / height (inches)²) × 703 for imperial units.

📊 BMI Categories

• Underweight (Below 18.5): May indicate malnutrition or underlying health conditions
• Normal Weight (18.5-24.9): Indicates a healthy weight for your height
• Overweight (25.0-29.9): May increase risk of health problems
• Obese (30.0 and above): Significantly increased risk of serious health conditions
