About this tool

Fórmulas clássicas para estimativa de peso ideal:

Broca: (altura em cm) − 100
Lorentz: mais ajustada para altura e sexo
Devine: usada em clínica (dosagem medicamentosa)
Hamwi: variante americana da Devine

⚠️ Peso ideal é uma estimativa. Composição corporal (% músculo vs gordura) é mais relevante que número absoluto na balança. Consulte um profissional de saúde.
