Calculation of the ideal weight according to the Lorentz formula

Attention, this calculation is not that of the BMI (Body Mass Index). This is a different measurement, you can find more information about BMI on this page .

Fill in your height (in cm) as well as your sex and we will calculate your ideal weight according to the Lorentz formula.

ORIGINS OF THE LORENTZ IDEAL WEIGHT & EXPLANATIONS

There are 4 popular formulas for knowing your ideal weight . The Lorentz formula is one of them (along with the formula of Monnerot-Dumaine , of Creff and of Broca ). This formula dates from the year 1929 ⁽¹⁾ .

This formula, even if it only gives a theoretical ideal weight, is used in geriatrics for example. In fact, the GNRI (Geriatric Nutritional Risk Index) takes Lorentz’s ideal weight ⁽²⁾ as a parameter .

The formula for men is: $P o i d s i d é a l (h o m m e) = H - 100 - ((H - 150) / 4)$

The formula for women is as follows: $P o i d s i d é a l (f e m m e) = H - 100 - ((H - 150) / 2, 5)$

Where the height is expressed in centimeters ( H value ) and the result is given in kilograms. This formula is therefore strongly inspired by that of Broca.
