WEIGHT STANDARDS

Each of us has an ideal weight, that is to say that corresponding to its size and is one of the pillars of good health. But nutritionists use to determine the standard weight of the body mass index (BMI). This measure is not "talking" as posted on the pounds the scale, and is the authoritative reference.

Body Mass Index

The BMI is calculated by dividing twice the number of kilograms by height:

BMI = weight / (height) 2

Example:
A woman measuring 1 m 65 and weighing 63 kg with a BMI 23.1 kg per square meter

Weight = normal BMI between 18.5 and 25 kg / m².

BMI (kg / m²)

BMI under 18.5:
Risk of morbidity (health): Low
Names: Underweight: thinness
Correspondence kg for a size of 1.70 m: <53

BMI of 18.5 to 24.9:
Risk of morbidity (health): Medium
Names: Normal weight or ideal weight or desirable weight
Correspondence kg for a size of 1.70 m: 53-72

BMI of 25 to 29.5
Risk of morbidity (health): Increased risk
Names: Overweight
Correspondence kg for a size of 1.70 m: 72-86

BMI from 30 to 34.9
Risk of morbidity (health): Serious Risk
Names: Obese Class I: moderate obesity
Correspondence kg for a size of 1.70 m: 87-101

BMI from 35 to 39.9
Risk of morbidity (health): High risk
Names: Obese Class II: severe obesity
Correspondence kg for a size of 1.70 m: 101-116

BMI greater than 40
Risk of morbidity (health): High risk
Names: Obese Class III: very severe obesity
Correspondence kg for a size of 1.70 m: above 116

The BMI is a reference technique to determine the limits of excess weight and especially the dangers inherent in them, that is to say, the "morbidity" a term which means the occurrence of diseases related toobesity such as diabetes andcardiovascular disease.

But this standard, very abstract, nothing evokes the actual number of pounds that we read on the dial of a scale.

Ideal Weight

A simple way to define your ideal weight is to apply the formula of Lorentz.

Male
Ideal weight = Height (in inches) - 100 - [(size - 150) / 4]

Male
Ideal weight = Height (in inches) - 100 - [(size - 150) / 2]

According to this calculation, the ideal weight for a woman of 65 is 1 m of 57.5 kg. A man of 70 is 1 m 65 kg.

This weight may not be suitable theoretical. Some women 1 m 65 are too round when they weigh 60 kg while others are delighted. And many men of 1 m 70 consider themselves too thin with 60 kg.

In fact, the margins of ideal weight were very broad.
