A BMI (Body Mass Index) calculator is a tool that uses a person's weight and height to estimate their body fat percentage, which can help determine if they are within a healthy weight range. It's a common method used by healthcare providers to assess an individual's health and risk factors.
BMI < 18.5 → Underweight
18.5 – 24.9 → Normal weight
25 – 29.9 → Overweight
30 and above → Obese
Underweight: May lead to nutrient deficiencies and low immunity.
Overweight: Higher risk of heart disease, diabetes, and joint issues.
Obese: Significantly increases health risks including hypertension and stroke.
