Verified Mathematical Model & Formulation
BMI = weight_kg / (height_m)^2 Ideal Weight (Devine Male) = 50 kg + 2.3 kg × (height_in - 60) Ideal Weight (Devine Female) = 45.5 kg + 2.3 kg × (height_in - 60) Normal BMI Range = 18.5 to 24.9 kg/m²
Computes Body Mass Index via standard metric height-to-weight ratio and calculates estimated Ideal Body Weight (IBW) using the Devine formula.
Configurable Parameters & Standard Units
- Biological Sex (1=Male, 2=Female): (Default: 1 count)
- Height (cm): (Default: 178 cm)
- Weight (kg): (Default: 78 kg)
Standard Worked Example & Practical Verification
Scenario: A female who is 165 cm (65 inches) tall weighing 72 kg.
Practical Takeaway: A modest reduction of 4.5 kg brings this individual into the standard healthy, lower-risk BMI spectrum.
Frequently Asked Questions
What is a healthy BMI range for adults?
According to the World Health Organization, a normal and healthy adult BMI falls between 18.5 and 24.9. Below 18.5 is underweight, 25.0-29.9 is overweight, and 30+ is obese.
Why is BMI sometimes misleading for bodybuilders?
Muscle tissue is significantly denser than fat. Elite athletes and bodybuilders with high muscle mass and low body fat can score a high BMI while being exceptionally fit.
