# Ideal weight - Formula and tables for calculating weight according to height

## Ideal weight - Formula and tables for calculating weight according to height Finding the perfect weight formula can seem like a daunting task. However, it is simpler than it seems.

Today, the ideal weight formula most commonly used by nutritionists is  the  body mass index,  also known as the Lorentz formula. Today, scientists offer another more accurate formula for ideal weight.

## Ideal weight formula

The formula for calculating the ideal weight first appeared in medicine in the form of a height of minus one hundred (h - 100). It was later corrected by Lorenz.

On the  formula of the ideal Lorentz weight (2):

• [(height in cm - 100) - (height in cm - 150) / 4)] for men
• [(height in cm - 100) - (height in cm - 150) / 2)] for women.

For example, a 180 cm man should weigh 72.5 kg. The Lorentz ideal weight formula was introduced in 1850. According to Lorenz, a woman 1.65 m tall should weigh 65 kg.

## Ideal weight - a new formula

While the classical Lorentz formula is valid, it is approximate. According to a group of scientists from Stanford, there are other formulas that are better convergent.

The ideal weight formula according to these specialists is (3):

Ideal weight = 22 * ​​square height (IBW = 22 xh  2  )

According to obesity experts, this algorithm is a better ideal weight formula because it is more suitable for the whole population.

Initially, it was used to calculate the calculation of drug administration, and later adapted to calculate the average ideal weight according to height.

It is also important to know that assessing a person's health, taking into account only the weight that marks the scale, is a mistake.

For example, a change in body weight may be due to an increase or loss of water. Focusing energy on finding a formula for calculating the ideal weight and achieving this figure without setting a goal to  eliminate body fat  is one of the most common mistakes in nutrition.

Calculating the ideal body fat percentage  and following up with a nutritionist is just as important. Finding the ideal weight by height should not be the only factor to consider.

## Ideal weight - excess fat or weight?

Why isn't the ideal weight formula the only thing that matters? Fat is twice as light as muscle. There are overweight men and women who are 1.80 m tall and weigh 80 kg. However, there are people with an athletic body with the same values.

While the body mass index will be similar in both cases. The percentage of body fat does not. If you have an ideal weight, but excess body fat, you may be at greater risk of cardiovascular disease.

## Ideal body fat percentage Although there is no formula for calculating body fat percentage, there are several methods. One of the most used is the caliper and tables. This method involves measuring the thickness of the  subcutaneous fat  folds in the abdomen. The values ​​obtained in millimeters are compared with the tables.

If you go to a nutritionist, they will try to bring you to two values: the ideal weight and the ideal percentage of fat.

In men, the ideal percentage of body fat varies from 14-18%. While for women the figure is 16-20%. Figures above 25% are an indicator of an unhealthy condition.

## Ideal weight table according to height

Below you can see a table with the ideal weight according to height. The following table is made from the previous formulas:

### Body Mass Index - BMI Outdated ideal weight formula?

Science has come a long way since the introduction of the first ideal weight formula. Lorenz was a pioneer in the application of body mass index theory.

BMI is still the official indicator for determining whether a person is overweight or not. This method of calculation works well when applied to obese people.

However, remember that BMI does not take into account the percentage of body fat. So reading only the BMI and the ideal weight formula according to height is not the most correct. There does not appear to be a relationship between mortality and normal BMI values. (3)
