What is "Ideal Weight"?
The concept of a single "Ideal Weight" is actually a myth. No two bodies are exactly the same. Muscle mass, bone density, and body frame size play a huge role. A bodybuilder might weigh 90kg and be healthy, while a sedentary person at 90kg might be obese.
However, for the general population, doctors use specific formulas and the BMI range to estimate a healthy weight zone.
The Formulas We Use
This calculator doesn't just guess. It uses trusted medical equations:
1. Healthy BMI Range (The Gold Standard)
This gives you a Range, not a single number. It calculates the weights at which your Body Mass Index (BMI) would fall between 18.5 and 24.9. This is considered the safest target for most people.
2. The Scientific Formulas
These formulas calculate a single "Ideal" number based on height and gender. They were originally developed for calculating medication dosages.
- J.D. Robinson (1983): Often used to calculate drug dosages.
- D.R. Miller (1983): A variation of the Devine formula.
- B.J. Devine (1974): The most widely used formula for medical purposes.
- G.J. Hamwi (1964): One of the earliest formulas for ideal body weight.
Limitations
These calculators do not account for muscle mass or body fat percentage. If you are an athlete or have a broad frame, your "ideal" weight might be higher than these results. Always listen to your body and consult a doctor.
