Many people consider that the calculation of the BMI is the only measure in order to calculate your ideal weight. But it's not necessarily true. The calculation of BMI required rate of obesity through a number only, but there are several additional ways you subtract other aspects related to the high weight dangerous. You more about the BMI.
This index is based on the ratio between the height and weight to determine the person who suffers from excessive obesity, which has a normal weight, who suffers from excessive weight and the weight is low.
But this is the best way to calculate your ideal weight?
To measure the BMI several disadvantages, since it is not estimated body shape and gives the possibility to understand the level of fitness, which begs the question: to what degree the BMI is useful? What are the other criteria that can be used to measure the weight?
The BMI, which measures the length-to-weight ratio, is divided into four sections:
Underweight: BMI below 18.5
Normal weight: BMI between 18.5 and 24.9
Overweight: BMI between 25 and 29.9
Excessive obesity: BMI of 30 and above
Claims that we are specialists when we take a large group - thousands or tens of thousands of people - for a specific search, it is difficult to use more advanced scale of the BMI. Calculate the BMI is cheap, fast and, in general, on average, gives acceptable standards can be used in these cases. But, for the sake of measurement of an individual person, is not considered a measure of the BMI scale better.
Traditionally, obesity is determined through a certain leap in the hierarchy of the BMI. In other words, obesity is determined by just a number. This standard does not give in many cases, no information about calculating your ideal weight. Assess the medical condition of the person, depending on the number one is an old and inefficient in the analysis of clinical levels for patients with excessive obesity.
Disadvantages of the BMI:
The BMI is just a number, does not reveal anything about the composition of the body - for example, the amount of muscle in the body than fat. Therefore, the conclusions that can rely only on the BMI can be misleading. For example, BMI has some people up, but they do not have a lot of fat in their body, but their muscle tissue increases the weight. It is possible that people who are located physical activity on a daily basis in this category.
Where resides fat?
Does the person seem like an apple or a pear? Could affect the whereabouts of fat on a person's health. Certainly, there are cases out of the base, but mostly, the fat located in the abdomen, or the form of the "apple", are the most dangerous in metabolic terms. When you accumulate fat in the waist area instead of the thighs, the risk of coronary heart disease and increase the risk of type 2 diabetes.
It possible to measure waist circumference helps to give us information about calculating your ideal weight.
The accumulated fat in the waist and thighs - image "الاجاصة" - is not considered harmful thing. "Many women gain weight at the bottom, so be Hodahn and larger Fajmahen, at a time when a narrow waist. Fats that break with the body does not pose a risk to the extent that posed by those in the abdomen."
Other ways to measure overweight
Any other ways except for the BMI can be used? These methods may need to use a measuring tape.
Waistline: It's very simple, measuring tape are tightened around the waist. To accurately measure your waist, must be surrounded by a measuring tape at the top of the hip articular (Articulatio coxae) and then on the lower back and down to the navel. Best hip circumference for men should not be more than 100 cm, and women no more than 86 - 87 cm.
The relationship between the waist and length: This method is based on the relationship between waist circumference and length. It is possible that this will be the most effective way of measuring waist circumference alone. This measurement is required to be a waist circumference less than half the length of a person.
The relationship between waist and hip: This method is based on the relationship between waist circumference and hip circumference. But do not recommend using this method.
Weight bio-mail (Bioelectrical impedance scales - Impedance bionics): This device sends an electronic frequencies for the body to estimate that the proportion of fat in the body.
There are other better ways to measure the proportion of fat in the body, such as the use of the MRI and DEXA imaging. However, these tests is impractical for most people. "These tests are much more accurate, but it's more expensive and it is difficult to take place, so they are often not considered the possibilities of disposable take place".
