Pana nu de mult, greutatea ideala se stabilea in functie de inaltime. Mai exact, daca aveai 1,75, se considera ca 65 de kilograme este greutatea ideala. O mare societate de asigurare din New York a stabilit, insa, alte formula de calcul, una speciala pentru barbate, iar alta speciala pentru femei.

Conform acestor formule greutatea ideala pentru barbati se calculeaza astfel:

50 + 0,75 x numarul de centrimetri peste 150 + 0.25 x numarul de ani peste 20.

Mai exact, un barbat de 30 de ani, cu o inaltime de 1,70, isi va calcula greutatea ideala astfel: 50 + 0,75 x 20 + 0,25 x 10 = 67,5 kg.

Pentru femei, valoarea din formula trebuie inmultita cu 0,9:

(50 + 0,75 x numarul de centrimetri peste 150 + 0.25 x numarul de ani peste 20) x 0.9.

Respectand datele de mai sus, o barbat de 30 de ani, cu o inaltime de 1,70, isi va calcula greutatea ideala astfel: (50 + 0,75 x 20 + 0,25 x 10) x 0.9 = 60.75 kg.
