## perfect weight

The ideal weight is linked to a particular length of life expectancy, [1] as it can not say that every person has an ideal weight of one, as it is influenced by many factors; Such as height, sex, body composition and the addition of fat and muscle, the size of the structure, and others, no doubt the importance of reaching healthy weight and maintain it, as it can help to prevent infection with many diseases and contribute to control, in addition to its importance to the health of the body in general , while increasing the risk of serious health problems; Such as heart disease, and type II diabetes, high blood pressure in people who are overweight or obese. [2] [3] [4]

## The method of calculating the ideal weight

There are many easy equations to calculate the ideal weight but these equations determine the weight one, and therefore prefer specialists to determine the scope of the targeted health weights, because there is no ideal weight of a specific proportion to all ages and races, and in any case can use the following equations to calculate the ideal weight approximate: [5]

• Equation of the ideal weight for men: the ideal weight in kg = 48 + 1.1 × (length in cm - 150 cm)
• Equation of the ideal weight for women: ideal weight in kg = 45 + 0.9 × (height in cm - 150 cm)

## Find out the ideal weight for age and height

In addition to the equations of ideal weight there are many other ways that can be used to determine the weight that should be accessible, including the following: [3]

### BMI

• Body Mass for adults indicator: It is calculated by dividing weight in kilograms to height in meters square, and is a measure of physical to evaluate the amount of fat total in the body, but it may not be appropriate for some groups and estimated the amount of fat in their bodies well, and these categories: senior age, athletes who have a large muscular structure, and some ethnic groups, and with the implications of the resulting values ​​comes from the body mass index account for Adults: [6] [7]
• Children's body mass index: normal amount of fat change in the bodies of children and adolescents, depending on age and sex, so the result of the body mass index is not interpreted as in adults; But translated into a set of percentage slide in private growth schemes for each sex and age (in English: Growth Charts) was developed in the Centers for Disease Control and Prevention (English: Centers for Disease Control and Prevention), these slides are used to classify weights as follows: [8]

### Ratio of waist to height

The measured ratio of waist circumference to height (in English: Waist-To-Height Ratio) One of the ways that can help predict the risk of heart disease, diabetes, and deaths are more effective than the body mass index, calculated by dividing the circumference measuring waist along the body, the measure was a person's waist less than half a length that is the result of the division is equal to 0.5 or less; It means that a person is close to a healthy weight, the risk of suffering health complications, life-threatening is low, [2] because the accumulation of fat in the abdominal area and around one of the causes of problems in the heart, liver, kidneys, and in general it should be noted that if waist greater than approximately 101 centimeters for men circumference, greater than approximately 88.9 cm for women who are not pregnant, it means an increased risk of developing complications of obesity. [9] [2]

### Ratio of waist to hip

It can be used to measure the proportion of waist circumference to hip circumference to see if a person is suffering from excessive weight, or it may be exposed to health risks because of this, where this ratio is calculated by dividing the circumference measuring waist circumference measurement of the hip; Which helps determine the amount of fat stored in the waist, hips and buttocks, in contrast to the body mass index, which compares weight to height only without specifying the pool area of ​​fat, can be through the scale ratio of waist circumference to hip assess the perimeter of the risk of heart disease and other health problems, explains the following table the possibility of exposure to health risks based on the resulting values ​​of this scale: [10] [11] [10]

### The proportion of fat in the body

Objects are different combinations and the content of fat and muscles based on several factors; Including lifestyle practice, diet, physical activity, and because of the different fat weight from one person to another, and the difference in the weight of body fat from the weight of his muscles; The indicators that depend on body weight only in determining the amount of fat in it as an indicator of body mass may not give accurate results when some of the people; Including the previously mentioned athletes who most of their body is made up of muscle, as increased muscle lead to weight gain; An error is calculated as fat, so it may be a measure of body fat is more effective than weight. [3]

It should be noted that there are many ways accurate to estimate the proportion of fat in the body through the use of a computer on the Internet that require measurement of both body weight, height, hip circumference, waist circumference, and the perimeter of the forearm and wrist circumference, can also visit the doctor or personal trainer to find out, in addition to the possibility of using special tools to measure the thickness of fat in certain areas of the body (in English: Calipers), and there are more sophisticated ways; Such as some sensors that broadcast an electric current through the body to calculate the percentage of fat in it, and after knowing the body fat percentage can be compared to the table the following to see if it is normal and healthy fat or excess alone, humiliation, taking into account teams Age: [3] [12]

As can be seen from the table above the proportion of fat in the body increases naturally the greater the age, the proportion of fat in women is higher than men, it is worth mentioning that the fat in the body is divided into two types, namely: basic fat; Which plays a role in many body functions and is essential for survival, while the second type is stored fat; It is protecting the internal organs in the abdomen and chest areas, the body uses to provide energy when necessary, and classifies people according to the proportion of fat in their bodies into several categories, so based on the American Council on the recommendations of the exercise (in English: American Council on Exercise), the more I forgot fat in the body is more person fitness, and while clarifying it comes to: [12] [2] [13]

## How to reach a healthy weight

It can be influenced by the human weight of many different factors; Such as the environment surrounding, behavior or habits, genes and family history, and the way that prevents the body of food and oxygen into energy which is the so-called metabolic (in English: Metabolism), and in general, the health way to reach a healthy weight is to follow a healthy diet, and if the person is suffering from obesity or weight gain; Reduce 500 prefer calories than the usual daily calories and increasing physical activity, and reduce the time it takes to relax. [4]

In the case of a person suffering from weight loss, it will do the opposite; Where he would prefer him to increase the number of calories per day; Through a balanced diet, in addition to eating snacks nutritious between meals and species selection of high-fat, including full-fat wholemeal, until it reaches the ideal weight for him, as the weight loss can lead to a lack of vitamins, minerals and other nutrients needed by the body to maintain his health, and to maintain a healthy weight must achieve a balance between the number of calories that enter the body by eating food and drink, and the number of calories the body to carry out respiration used by digestion and physical activities and others, and is not required to balance full between them every day, but to achieve over a period of time. [14] [4]

### What is the ideal weight for women

As previously mentioned can calculate the ideal weight for women through the following equation: [5]

• Ideal weight in kg = 45 + 0.9 × (height in cm - 150 cm)

### What is the ideal weight for a man

As previously mentioned can also calculate the ideal weight for a man through the following equation: [5]

• Ideal weight in kg = 48 + 1.1 × (length in cm - 150 cm)
