Frequently asked questions
¿Se puede tener un peso ideal menos indicativo que el IMC?
Las fórmulas de peso ideal son orientativas y no distinguen músculo de grasa. El IMC y la circunferencia de cintura aportan información complementaria.
¿Por qué las fórmulas dan resultados distintos?
Cada fórmula se creó con poblaciones y criterios diferentes. Por eso mostramos un rango entre los cuatro métodos en lugar de un único número.
Can ideal weight be less indicative than BMI?
Ideal weight formulas are indicative and do not distinguish muscle from fat. BMI and waist circumference give complementary information.
Why do the formulas give different results?
Each formula was built with different populations and criteria. That is why we show a range across the four methods instead of a single number.
