How to calculate normal weight for each age? Normal weight and height for women: the ideal ratio How to determine your body type

All women dream of being at their ideal weight. Rivers of information in the form of all kinds of advertisements for drugs that promise a slim and beautiful body, fashion magazines and shows that extol slender models, create a general concept that beauty can only have a physical form. The women of Rubens's era with their luxurious curvaceous figures are long gone. But besides physical attractiveness, a woman’s health plays a huge role.

Woman's weight and health

For women, excess fat in the belly area carries greater health risks than excess fat in the hip area. This can provoke high blood pressure, a predisposition to diabetes and the early development of coronary heart disease. There is a lot of debate about what a woman's weight should be. But the clear argument is that a beautiful woman is, first of all, a healthy and happy woman. And its weight plays an important role in this.

Methods for calculating ideal weight

For quite a long period of time, Broca's formula was used to calculate the ideal body weight. This is an accessible way for everyone to calculate the ideal weight for a specific height and age. Everything is quite simple, just know the woman’s height and weight: subtract 100 from her height in centimeters and you will have the ideal weight. But this formula is more likely to be suitable for calculating weight for women 40-50 years old. For 20-30 year old ladies, the ideal weight will be 10-12% less, and for ladies over 50 years old the number increases by 5-7%.

Nowadays various formulas and tables are used more, which also take into account body type. To find out how much weight corresponds to the ideal weight from a medical point of view, you should calculate BMI using the formula: body weight in kg divided by height in meters squared B/(P*P). For example: height - 180 cm, weight - 75 kg.

It turns out: 75 / (1.8 * 1.8) = 23.1.

In addition, BMI is influenced by gender, body type and age. It turns out that over the years the composition of the human body changes, as well as the mass of muscle and fat tissue. Therefore, new formulas have emerged that take into account the age-related characteristics of a person’s physique. First, BMI is calculated using the formula: height in centimeters divided by weight in kilograms squared. Then, to calculate BMI by age, you should use age adjustment.

How to calculate BMI by age and body size?

Taking into account the woman's age, the ideal BMI looks like this:

• from 19 to 24 years old - 19.5;
• from 25 to 34 - 23.2;
• from 35 to 44 - 23.4;
• from 45 to 54 - 25.2;
• from 55 to 64 - 26;
• over 65 - 27.3.

If we consider BMI norms, then everything is very individual. It should be borne in mind that the norm for women depends on her age. At 25 years old and at 50, the ideal weight for a woman may be very different. The BMI table may not be correct for teenagers, older people, women during pregnancy and lactation, and athletes. This index is used for men and women from 20 to 65 years old.

A normal weight should be between 18.5 and 25. If the index is below normal, there is a risk of a lack of nutrients the body needs. An index from 25 to 29 indicates overweight, and an index exceeding 30 indicates obesity. The more your BMI is above normal, the sooner you need to start losing weight. This will not only make your body lighter, but will also reduce the risk of coronary artery disease, diabetes and hypertension. But not only height and age influence the ideal weight for a woman; the table also takes into account the woman’s body type, since frail and large women have very different ideal weights.

Table of optimal weight for any body type

To correctly show the ideal weight for a woman, the table must have a slight adjustment. This is a correction for young girls.

For women aged 18-25, to calculate their weight, subtract 0.45 kg for each year up to age 25.

Choosing an individual weight loss plan

The path to an ideal weight is simple: to be in good shape, you should not overeat and you should move more. The main rule is no extremes and no fasting. The number of calories you burn daily depends on your level of physical activity. Therefore, depending on the daily calorie intake and physical activity, each woman has her own to get the ideal weight. For a woman, the table below will be useful to calculate nutrition, taking into account the level of physical activity.

It follows from the table that a woman leading a moderately active lifestyle can consume about 1,500 kcal per day without changing weight. However, if you plan to lose excess weight, you will have to limit yourself. Practice shows that when the calorie content of the daily menu is reduced to 1200 kcal, weight loss occurs gently, quickly, effectively and without causing harm to health.

How to lose weight?

Having chosen your personal weight loss plan, you need to plan your diet daily, combining different types of foods: carbohydrates, proteins, fruits, vegetables, dairy products, fats - so as not to exceed the permissible amount of daily calories. it should be done gradually, changing the menu and increasing physical activity.

The most acceptable rate of weight loss is no more than 500-800 g per week. If you reduce body weight at a faster pace, there is a risk of burning not only excess fat, but also muscle tissue. And muscles provide not only physical strength, but also metabolic rate. The more developed the muscles, the easier it is to maintain normal weight. To lose half a kilo of fat in a week, you need to give in 3500 kcal more during this time than you eat. You can eat less food, but by cutting back on your diet, it is difficult to preserve the necessary nutrients in it. It is much easier and healthier to gradually reduce the calorie content of food and increase the physical activity of the body.

How does a woman's weight change?

Nutrition, as well as weight norms for women, can change throughout life. During pregnancy, a woman becomes heavier, especially in the last trimester. On average, during the period of bearing a child, she gains from 11 to 16 kg. In the first trimester, the energy needs of her body increase slightly, and then the body needs to receive an additional about 300 kcal per day, including the necessary vitamins and minerals. Pregnancy and childbirth, as well as caring for a baby, require enormous amounts of energy. Therefore, a young mother needs more nutrients, and therefore calories.

But all young mothers strive to regain their prenatal slimness and elegance as quickly as possible. However, it is better to wait with the diet, because breastfeeding and pregnancy deplete the reserves of vitamins and microelements, so the young mother should receive adequate nutrition, both for herself and for the child. When breastfeeding, it is recommended to increase the daily calorie intake by about 500 kcal at least for a while until the milk supply stabilizes and only then very gradually reduce the amount of calories consumed in order to lose weight.

7 rules for losing weight

Each woman chooses her own most suitable way to lose weight, but there are basic rules for proper weight loss that cannot be neglected. You should drink a glass of water before each meal. This helps fill your stomach and avoid overeating. It is important to have breakfast. Otherwise, too much will be eaten at lunch. If you don't have an appetite early in the morning, you can take a light breakfast with you to work. You should chew food as long as possible: the slower the food is absorbed, the faster the feeling of hunger goes away. You shouldn't eat on the go. Be sure to first sit down at the table and then start eating.

You should only go to the store on a full stomach, buy products strictly according to the planned list, and not allow yourself extra sweets. Limit your intake of fatty foods, because fat has 2 times the calorie content of proteins and carbohydrates. Other foods should be taken in moderation. Vegetables can be eaten without restrictions. If you want a supplement, you should not take it right away, but wait 5-10 minutes; the body will probably receive a signal of saturation and you can abstain from the supplement.

Ideal weight and psychological dependence

Every woman should approach the process of losing weight wisely, because many, having a normal body mass index, are dissatisfied with their appearance and strive to lose weight as much and quickly as possible. You need to take everything into account: weight and age. It should be remembered that rapid weight loss leads to a weakening of the body's regenerative forces, causing various pathological processes in it. And the problem of dissatisfaction with one’s weight, first of all, is in the head and the psychological attitude of one’s beloved.

Table of weight in relation to height for women

Height and weight chart for men

Before losing or gaining weight, you need to calculate this ideal weight for yourself. You need to analyze your data to find out the criteria for ideality.

All people are different, thin or thick, short or tall, everyone cannot look the same. And for everyone to be 90 – 60 – 90, this cannot happen either. Many people make the mistake of trying to fit a figure like their idol. But each person is individual, with his own proportions and body type.

How to find the golden mean to amaze with your slimness and glow with health. First of all, we determine your body type. Professor Chernorutsky V.M. distinguished the following body types: 1 - asthenic, 2 - normosthenic and 3 - hypersthenic.

To determine the type, you need to measure the circumference of your wrist. The asthenic type includes women with a wrist circumference of less than 15 cm, men less than 18 cm. If a woman’s wrist circumference is from 15 to 17 cm, and a man’s is from 18 to 20 cm, then this is a Normosthenic physique. The hypersthenic body type includes women whose wrist circumference exceeds 17 cm, and in men more than 20 cm.

Representatives of asthenic physique are thin people whose height is above average. Their limbs are elongated, their shoulders are narrow, their neck is long and thin, and their chest is flat and narrow. They often lack stamina and strength because their muscles are poorly developed. But they are graceful, energetic and light, less prone to obesity than other representatives of body types. For people in this group, it is better to give preference to such sports disciplines as: dancing, aerobics, swimming. To develop endurance and strength.

Normosthenic physique. Representatives of this group have proportional body sizes. They are of average height. Their legs are slender, their waist is thin, their figure is beautiful and harmonious. Representatives of this type of cutting are fast in their movements and have good coordination. To keep fit, they are suitable for tennis, water aerobics and team sports (basketball, handball and volleyball).

Hypersthenic physique. Representatives of this group have heavy and wide bones. They are stocky and not too tall. Their shoulders are voluminous, their torso is wide, and their limbs are short. They are very hardy and strong, but nature has deprived them of flexibility and grace. People of this type tend to be overweight because their metabolism is not fast. To keep fit, they are recommended the following sports disciplines: yoga, martial arts and callanetics.

A person’s body weight depends on their body type, height and age. And yet, how to calculate the ideal weight for a height of 160 cm. To accurately calculate, you can use the Quetelet index. This index was calculated by the Belgian statistician and sociologist Adolphe Quetelet back in 1869. Body mass index (BMI) is a value that allows you to relate weight to a person’s height.

And gives a definition regarding weight. According to this, people of asthenic body type have 325 g for every centimeter of height. 350 g – normosthenic and 375 g – hypersthenic body type. For example, a woman with an asthenic build and height of 160 cm should weigh: 160 x 325 = 52 kg. But age categories must also be taken into account.

For the relationship between height and age, there are the following indices: Asthenic body type - at the age of 15 - 18 years, the index corresponds to 315; from 19 to 25 years old it is 325; and from 26 to 40 years old 335. Normosthenic type – 15 – 18 years old is 325; 19 -25 years is equal to 345; and 26 - 40 is equal to 360. Hypersthenic type - 15 -18 years old corresponds to 355; 19 -25 years 370; and 26 – 40 corresponds to 380. So, knowing your height, age and body type, you can easily calculate your ideal weight.

But what if, after calculation, a person’s height does not correspond to his weight. To determine the degree of weight deviation, you can use Quetelet's formula. BMI is equal to: body weight in kg divided by height squared in m. That is, 60 kg is body weight, and height is 1.6 m, we get: 60: (1.6 x 1.6) = 3.4.

Knowing the body index from the correspondence table, it is easy to determine the ratio of weight and height. With a BMI of 16 or less, weight deficiency is clearly visible. From 16 to 8.5 - mass deficiency. From 8.5 to 25 is the norm. From 25 to 30 – preobese, overweight. From 30 to 35 – 1 degree of obesity. From 35 to 40 – 2nd degree of obesity. From 40 and above – 3rd degree of obesity.

This classification was developed by the US National Institutes of Health and has been approved by WHO (World Health Organization). These indicators are widely used throughout the world. So, the index 3.4 shows that the weight corresponds to the norm, therefore, the ideal weight for a height of 160 cm is 60 kg. The problem of ideal weight worries not only people who take care of their appearance, the same problem worries doctors. Since extra pounds entail serious problems: cardiovascular diseases, early atherosclerosis, diabetes.

If a person feels comfortable, is healthy and energetic, and has an extra 3-5 kg, is it worth losing them? Being in harmony with yourself is more important than having ideal parameters.

The great Leonardo da Vinci was one of the first to study and define the ideal parameters of the human body. The anatomical proportions he presented are still studied in art schools all over the world. From Leonardo da Vinci’s theory of ideal proportions it follows that the volumes of the chest, waist and hips, taken separately, do not solve anything, it’s all about their ratio.

In modern society, changes in the parameters of the human body (anthropometric data) are revised every 15 years, because during this period, as a result of the acceleration process, changes in size, proportions and shapes occur figures person. The well-known 90 – 60 – 90, of course, are not the standard of ideal women's proportions for everyone. Body proportions generally cannot be the same for all women, since there are different body types given to us genetically.

Main body types

The main body types include asthenic (thin-boned), normosthenic (normal-boned) and hypersthenic (broad-boned).

• Women with an asthenic (thin-boned) body type have thin bones, long limbs, a thin neck, and muscles are relatively poorly developed. Representatives of this type are usually light in weight, they are energetic and active. Eating plenty of food for quite a long time does not lead them to gain weight, since they spend energy faster than they accumulate. If a woman of this type does not have a very thin waist and normal, not narrow hips, everything seems miniature because of the thin bone.

• The physique of normosthenic women (normal bone type) is distinguished by the proportionality of the main body dimensions, the correct ratio. Most beautiful female figures are found precisely with this body type.

• In representatives of a hypersthenic (big-boned) physique, the transverse dimensions of the body predominate. Their bones are thick and heavy, their shoulders, chest and hips are wide, and their legs are sometimes somewhat short. Women of this type need to remember that they tend to be overweight.
  

You can determine your approximate body type by measuring the circumference of the wrist of your working hand. For normosthenics it is 16-18.5 cm, for asthenics - 16 cm, and for hypersthenics - 18.5 cm.

Quite often there are mixed body types with a predominance of the parameters of the above types.

If we talk about gradations female height, then they are as follows: low height - 150 cm and below, below average height - 151-156 cm, average height - 157-167 cm, high - 168-175 cm, very tall - 176 cm and above.

True, in recent years this gradation needs to be changed taking into account the acceleration of modern youth, so normal height can be considered for normal and large-boned people from 166 to 170 cm, and for thin-boned people from 168 to 172 cm.

Correct legs

There are certain proportions between height and leg length. Legs can be considered short if their length is less than half the height. Can be considered proportional figure when the length of the legs is more than half the height. Forfor broad-boned people, preferably by 2-4 cm, for normal-boned people - 4-6 cm, for thin-boned people - 6-9 cm. For example, ifIf you have a normal bone body type with a height of 168 cm, the length of your legs is 90 cm, then this is ideal.

The length of the legs should be measured from the protrusion of the femur to the floor. In cases where the legs are somewhat shorter than the accepted norm, shoes with heels will help change this ratio, since they visually eliminate the existing imbalance.

The diameter of the leg at the calf, depending on the body type, ranges from 36 to 40 centimeters, at the ankle from 16 to 20 cm. Experts even tried to compile a table of the ideal leg shape depending on the body type.
Here are the approximate parameters: with a height of 156 and a weight of 50 - 55 kg - leg circumference at the hip from 48 to 54 cm, in the calf 31-32 cm, in the ankle 18-20 cm; with a height of 160 and a weight of 55–58 kg, the leg circumference at the thigh is from 50 to 56 cm, in the calf 32–35 cm, in the ankle 19–22 cm; with a height of 167 and a weight of 56-65 kg, the leg circumference at the hip is from 52 to 58 cm, at the calf 33-36 cm, at the ankle 22-23 cm.

And above all, ideal legs should have three gaps between them. To do this, you need to stand in front of a large mirror and put your feet in the position - heels together, toes apart. You should see the first gap under the knees, the second at the ankles, and the third at the top closer to the hips. In other places the legs should converge.

Correct weight

Body weight depends on the body type, height and, very importantly, the age of the person. One option for calculating weight is the Quetelet index. According to this index, for women with a thin-boned body type, it is enough to have 325 g for every centimeter of height, for normal-boned women - 350 and for large-boned ones - 375 g. Then the index is multiplied by height, and the weight corresponding to your parameters is obtained.
It must be emphasized that the ideal weight of women, especially those whose height is below 160 cm, should be 10-15% less than normal. For short women, at least under 20 years of age, it is advisable to weigh 3-5 kg ​​less than normal, i.e. calculated using the Quetelet index.

As mentioned above, body weight also depends on age. The table shows the weight-to-height ratio (weight in g divided by height in cm) for women aged 15 to 40 years.

To determine your normal weight, you need to multiply your height in cm by the weight-height coefficient corresponding to your age and body type.

Excess weight can be tracked by measuring the fat fold on the abdominal wall, above the navel, 3 cm from the midline. Its thickness should normally be from 1 to 2 cm.

Hips, waist and chest

Knowing your body circumferences - chest, waist and hips - also helps determine your body type. Suchthe indicator is called "whites".

Normal whites indicators for young women (18 - 28 years old) of a normosthenic body type can be considered if the chest circumference is equal to half the height plus 2-5 cm, for the bust - chest circumference plus 8-10 cm, for the waist - standing height, minus 100, hips should be greater than the waist circumference by about 25-30 cm. For thin-boned women, it can be considered normal if their chest circumference is in the range of 84-86 cm, and their bust is plus 4-6 cm to the indicated figures.
Their waist is usually thin, ranging from 60-64 cm, and their hip circumference is approximately 25-30 cm larger. In women with a broad-boned body type, the chest circumference exceeds half the height by 8-10 cm, chest - by another 8-10 cm. The waist circumference with a height of 166-168 cm is within 70-76 cm, and the hip circumference is larger by the same 25-30 cm.

Devendra Singh, professor of psychology at the University of Texas, came to approximately the same conclusion in the early nineties. Only he calculated the proportion between the hips and waist as a percentage. According to his theory, the ideal proportions are those in which the waist volume is from 60 to 70% of the hip volume.

To do this, you need to divide the waist volume by the hip volume, the resulting coefficient should be from 0.6 to 0.7. By the way, the ideal beauties according to this ratio are the Venus de Milo - 70% and the Nude by Rubens, the same 70%. But among real women, the waist-to-hip ratio is ideal: Marilyn Monroe 0.61 (56/91.5), Brigitte Bardot 0.66 (58.5/89), Demi Moore 0.72 (66/91), Claudia Schiffer 0.67 (62/92), Cindy Crawford 0.69 (58/84), Gisele Bundchen 0.70 (61/86), Kylie Minogue 0.70 (63/89).

Doctors believe that the ratio of waist circumference to hip circumference should not exceed the endocrine balance coefficient, which is 0.85. If your waist does not exceed 85% of your hips, then your figure in perfect order both from an aesthetic and medical point of view.

Time moves forward, new criteria for assessing the beauty of a female figure appear. The latest analysis of the results of an anthropometric examination of women, carried out in our country at the beginning of 2000, showed significant changes in body proportions. Young women have longer arms and legs, a higher waistline, wider shoulders with the same body size, and improved posture. So we can conclude that the young and middle generations of women have become taller and slimmer than the previous generation. Well, if your parameters do not match the ideal ones, don’t be upset! Still, the most important thing in a woman is her individuality and, of course, her well-groomed appearance.

What should be the weight for a height of 160, 164, 170 cm? This question worries many men and women: both those who dream of losing weight and those who have long been trying to gain the missing kilograms in order to make their figure more attractive. Despite the fact that the indicators of an ideal physique are relative, today more and more people are trying to “try them on”, forgetting that it is important to take into account not only your height, but also your age and body type, since each person is individual and has his own norms. So, what should the ideal ratio be and how to calculate it?

Calculation methods

Determining your correct weight is quite easy. To do this, you just need to resort to a few simple formulas. In most of these formulas, body length is denoted as h and weight as m. Similar methods for calculating ideal body parameters have been known for many years, and some of them are even successfully used in medicine and sports.

Broca's formula

The simplest and long-used algorithm for such calculations is Broca's formula. It looks like this:

• m = h - 100 (for height up to 165 cm);
• m = h - 105 (height 165-175 cm);
• m = h - 110 (over 175 cm).

Thus, to calculate your ideal weight, you need to measure your body length and subtract a certain coefficient from this number, taking into account the characteristics of your physique. For example, weight for a height of 170 cm should be 65 kg (170 cm minus 105). When making this calculation, you must pay attention to your body type. Brock's formula is designed to determine the ideal body weight for normosthenics (people with a proportional figure). If your body type is asthenic (long limbs, weak muscles, thin bones), you need to subtract 10% from the body weight obtained by the formula, if you have a hypersthenic body type (wide chest, wide hips, short legs), add 10%. Based on these data, you can calculate, for example, what the weight should be for an asthenic girl with a height of 165. This figure will be 54 kg.

To correctly determine what body type you are, measure the circumference of your wrist (it’s easiest to do this with a measuring tape). In women of the asthenic type, this figure will be less than 15 cm, in men - less than 18 cm. For women who are normosthenics, the typical value is from 15 to 17 cm, for men of this type - from 18 to 20 cm. In hypersthenics, the wrist girth is more than 18 cm (for female) or 20 cm (for males). Having accurately determined your body type, you can easily calculate your ideal weight indicators, adjusted for the individual characteristics of the body structure.

Body mass index

Another well-known way to determine whether your body type is normal is to calculate your body mass index (BMI).

This method makes it possible to find out whether you need to lose weight or gain weight and what your risk of obesity and various diseases associated with it is. To calculate BMI, you need to divide your weight in kg by the square of your body length in m and multiply by 2. For example, with a body weight of 70 kg and a height of 175 cm, the body mass index formula will look like this: 70: (1.75* 1.75) = 22.9. The results of this calculation are interpreted as follows:

• BMI 16 or less: severely underweight, very low risk of obesity;
• from 16 to 18.5: underweight, low risk of obesity;
• from 18.5 to 24.99 is considered normal. With proper nutrition, the possibility of developing obesity is negligible;
• from 25 to 30: overweight, high risk of obesity and related diseases;
• from 30 to 35: obesity I degree;
• from 35 to 40: obesity degree II;
• over 40: grade III obesity.

BMI indicators will help you navigate the need to adjust your body weight. BMI numbers that are too high or too low are equally dangerous for the body. Most often, the BMI formula is used to estimate body weight in a clinical setting. It is suitable for determining normal weight in both men and women.

other methods

The Lorenz method is a very simple and no less well-known method for determining ideal weight parameters: for it you only need to know the length of your body in cm. The height indicator must be divided by 2 and subtracted 25 (H/2 - 25). So you can calculate, for example, what weight should be for a man with a height of 180: 180/2 - 25 = 65 kg.

The Lorenz method can be considered a rather conventional way of determining normal body weight. It does not take into account a person's physique, and therefore only gives approximate figures. However, these numbers are very close to those obtained by using other, more labor-intensive calculation methods.

Another way to get results that are as close to reality as possible is the Cooper formula. It cannot be classified as frequently used, since it requires longer calculations. The method takes into account the physiological differences between men and women, therefore it has 2 calculation algorithms. For females, normal body weight is calculated using the formula (H (cm) x 3.5: 2.54-108) x 0.453. For men - (H (cm) x 4.0: 2.54-128) x 0.453. So, for a girl 164 cm tall, the ideal weight, according to this method, will be (164 x 3.5: 2.54-108) x 0.453 = 53.5 kg. There are also lesser-known and popular ways to calculate normal body weight. These include the determination of the Breitman index (h (cm) x 0.7 - 50 kg) and the Noorden index (h (cm) x 420/1000).

Normal ratio indicators

For those who do not want to spend time studying various algorithms, there are averages for normal weight according to height. In this case, the gender of the person must be taken into account. For example, for women there are the following standards:

• 142 cm - 46 kg;
• 145 cm - 47 kg;
• 147 cm - 49 kg;
• 150 cm - 50 kg;
• 155 cm - 53 kg;
• 158 cm - 54 kg;
• 160 cm - 56 kg;
• 163 cm - 58 kg;
• 165 cm - 60 kg;
• 168 cm - 62 kg;
• 170-172 cm - 64 kg;
• 173 cm - 65 kg;
• 175 cm - 67 kg;
• 176-178 cm - 69 kg.

Of course, these indicators are approximate and very conditional. The numbers can vary both up and down depending on your body type and age. For asthenics they will be smaller, for hypersthenics - larger, the difference will be on average 4-5 kg, less or more, respectively. The table of ideal height and weight for a girl will tell you more about this.

• with a body length of 1.55 - 1.58 m - 56-58 kg;
• 1.6 - 1.65 m - 59-62 kg;
• 1.68 - 1.7 m - 64-66 kg;
• 1.75-1.78 m - 69-72 kg;
• 1.8-1.83 - 74-76 kg;
• 1.85-1.88 m - 78-80 kg;
• 1.9 m - 82 kg.

The table below for weight and height norms for men can provide more accurate information. In it, the ratio is determined in connection with the body type.

When determining your ideal weight, you should pay attention not only to height indicators, but also to age. Children and teenagers have their own standards; their weight is always lower than that of adults. At the same time, the table takes into account the division by low, medium and high growth rates. Short children weigh accordingly less than their tall peers.

With age, body weight increases, so for people over 40 years old, their own standards have also been developed. For example, by the age of 40, a woman’s normal weight increases by 10-15% compared to what she had at the age of 20. If at the age of 20 a woman weighed 56 kg, then it is natural that upon reaching middle age this figure will change to 61-63 kg.

In matters of correcting your own figure, you should not rely solely on average tables and standard formulas, since they do not take into account the individual structural features of your body. For the same reason, there is no need to strive for the ideal indicators prescribed in such average tables. They can only tell you in which direction you need to move and whether you have a tendency to gain extra pounds or lose weight. However, if the weight-to-height ratio deviates noticeably from the norm, this may be a reason to visit a doctor, as it may indicate the presence of serious health problems.
