⚖️ Understanding BMI
Body Mass Index (BMI) is a simple screening tool that uses height and weight to estimate body fat. While BMI doesn't directly measure body fat, it's widely used as a general indicator of whether a person has a healthy body weight for their height.
📏 BMI Categories
📉 Underweight
BMI < 18.5
Below normal weight
May indicate nutritional deficiencies
Potential weakened immune system
✅ Normal Weight
BMI 18.5 - 24.9
Generally healthy weight range
Lowest risk for weight-related issues
Good baseline for most people
⚠️ Overweight
BMI 25 - 29.9
Above normal weight range
Increased risk for certain conditions
May benefit from lifestyle changes
🚨 Obese
BMI ≥ 30
Significantly above normal
Higher risk for serious health issues
Medical attention recommended
⚠️ Medical Disclaimer: BMI is a screening tool, not a diagnostic tool. It doesn't account for muscle mass, bone density, or body composition. Always consult with a healthcare professional for personalized health advice.
