Devine formula for water calculate. Methods for determining excess weight and calculating the caloric content of the diet. Ideal body weight

The body mass index (BMI) is an indicator that is calculated based on the ratio between a person's height and weight. BMI defines the range in which body weight can vary for a given height.

There are many formulas for calculating normal and ideal weight, but each of them is very approximate and can only serve as a rough estimate. Some formulas do not take into account body type, body fat percentage, and skeletal bone density, which varies from person to person.

In athletes, BMI can be high due to musculature, which is denser and heavier than adipose tissue. A BMI within the normal range also does not indicate an ideal physique and the absence of health problems. Initially, BMI was used in medicine to select the optimal treatment and prescribe the correct dose of drugs, and then found wider use.

To calculate the table, select the daily calorie content

For healthy weight loss, you need to reduce the number of calories that enter the body during the day. First you need to calculate the amount of energy consumed by the body for basal metabolism. It is equal to 1 kcal × 24 hours for every kilogram of weight. To this you need to add the calorie intake, which is calculated depending on your type of activity and lifestyle.

With age, people begin to lead a more relaxed and sedentary lifestyle. With a decrease in physical activity, the caloric content of the diet should also decrease.
Planned calorie deficit may vary depending on body type and amount of overweight, but should not exceed 600 kcal per day.

The best way to lose weight is to reduce the calories consumed per day by 200-300 units in parallel with the increase in physical activity. Two hours of intense training provides a loss of 500 kcal.

The more the ratio between muscle and fat mass increases in favor of the muscles, the more calories begin to be spent on the main metabolism, since the growth of muscle mass requires increased nutrition and energy consumption for its maintenance.

Daily nutrition should be balanced and follow the formula: proteins / fats / carbohydrates = 30% / 20% / 50%. Compliance with this formula guarantees the most effective result in the process of weight loss. Diets with a sharp reduction in one of the components of the diet (proteins, fats or carbohydrates) cannot be followed for a long time.

Once a week, you can spend fasting days on kefir, cottage cheese, apples, buckwheat, rice, etc. The duration of such a mono-diet should not be more than 1-2 days.. On fasting days, the number of meals can be increased up to 8-10 times a day, the amount of fluid you drink is up to 2.5 liters. Fasting days should be alternated.

You want add 21 kg.
With this calorie difference, you can
average raise your weight on 270 grams in Week,
and achieve the desired result by:

Losing excess weight takes time. After all, excess weight also did not appear instantly, but accumulated over the years. Any strict diet promising fast weight loss in a short time, very harmful and hazardous to health. Their consequence can be serious metabolic disorders in the body, the recovery of which will take a long time.

In order for the weight loss process to be safe, you should lose about 2-3 kg per month, or no more than 3-5% of your original weight. With a sharper weight loss, sagging of the tissues is inevitable, their loss of elasticity, which will negatively affect the appearance and figure.

The calorie deficit of the diet should not exceed 600 kcal per day. The best way to lose weight is to reduce the calories consumed per day by 200-300 units and increase physical activity. Two hours of intense training provides a loss of 500 kcal.

If the goal is weight gain, then you need to increase the calorie content of the daily diet and the frequency of meals (up to 5-6 times). Anaerobic exercise is also a must.

Once a month, it is necessary to recalculate calories depending on changes in body weight.

You can determine your body type by the circumference of your wrist.

Your Ideal Body Weight:

You:

There are three main body types: asthenic (thin-boned), normosthenic, hypersthenic (broad-boned). It should be noted that the type of physique is laid genetically: a plump asthenic will never turn into a hypersthenic, just like an emaciated hypersthenic will never turn into an asthenic.

Signs of asthenics are narrow shoulders and pelvis, a short torso, long legs and arms with narrow hands and feet, a long, thin neck, a small amount of subcutaneous fat, and poorly developed muscles. The broad-boned type is characterized by broad shoulders, a pelvis, a chest, a long torso with short legs, wide hands and feet, and a tendency to be overweight. Normosthenics occupy an intermediate position between these two types and differ in the proportionality of the figure.

Body type is usually determined by the size of the circumference of the wrist:

• If the wrist circumference is less than 15 cm (for women) and less than 18 cm (for men), then this is an asthenic.
• If the wrist circumference is 15-17 cm and 18-20 cm for a woman and a man, respectively, then this is a normosthenic.
• You are hypersthenic if the wrist circumference is more than 17 cm (women) and more than 20 cm (men).

You can also determine the body type using a simple trick: grasp the left wrist with the index and thumb of the right hand. If the fingers do not close - you are a hypersthenic, if they close butt - you are a normosthenic, if the fingers overlap each other - you are an asthenic.

You: physique not defined

This table was compiled by Dr. Margaret Ashwell to determine the health risk depending on the type of figure, based on the relationship between height and waist size. This method of assessment is suitable for both women and men.

When fat is deposited in the waist area, it increases its circumference and makes a person look like an "apple". With such a physique, the risk of developing cardiovascular diseases, hypertension, diabetes, and oncological processes increases dramatically.

When excess fat accumulates in the lower abdomen, thighs and buttocks, the body becomes pear-shaped. This is less of a health hazard.
Too thin when the figure becomes similar to "capsicum", may also indicate health problems (with the exception of pronounced asthenics).

If you are in the pear zone, there is no cause for concern. If you are in the apple-pear zone, you should be more attentive to your health and not allow an increase in waist circumference. If you are in the "apple" zone, you need to take action, your health is at risk.

Normally, the waist circumference should be less than half the height. As the famous French proverb says, "the thinner the waist, the longer the life".

The number of calories you need per day:

The number of calories you need per day for weight loss:

Important: to maintain health during weight loss, the number of calories consumed per day should be 1000-1200 kcal for a woman, 1200-1500 kcal for a man.

→ If you need 1100 kcal per day for weight loss, calculate the average number of servings between 1000 and 1200 kcal.

The table below will help you figure out what one serving is equal to.

The composition of one dietary serving

1 cup (200 ml) is a common measure taken by nutritionists to measure serving size.

All food groups except starchy foods can be eaten at any time and in any combination of them. Starchy is recommended to be consumed in the morning or afternoon, but not in the evening for dinner.

Fat mass:

"Net" body weight (without fat):

Basal metabolic rate:

Calories needed per day:

Body fat percentage is an important indicator of health and fitness levels. Fats play an important role in the body, but the amount of fat should not go beyond certain norms. A simple weighing is not enough to determine these limits, since it does not provide information about the ratio of muscle mass to fat.

Normally, the amount of fat in the body should be at least 13% and not more than 34% (for women) of the total body weight.

Determining your body fat percentage is especially important for athletes. The effect and the right direction of a training program can only be assessed on the basis of this indicator.

There are various methods for determining the content of fat in the body, from ultrasound to measuring the thickness of fat folds.

The fat calculator takes into account the volume of the waist, hips and neck. Such a parameter as neck circumference is taken into account because it begins to change last when gaining weight, only with extreme degrees of obesity, therefore, it can be used to determine the body type of a person.

Calculator ideal body weight is designed to calculate the optimal weight, which represents a combination of maximum life expectancy with a minimum probability of death from a number of diseases (hypertension and diabetes, coronary heart disease, etc.). Meaning ideal body weight depends on the height of a person, his gender and physique (type of constitution). To use the calculator and calculate ideal mass of your own body, fill in all the fields of the form below in sequence. Registered and authorized users of our Internet portal can save the results of their calculations in the "favorites" section of their personal account and return to them later.

Ideal body weight

At the moment, it is considered ideal to consider such a body weight that is statistically significantly combined with the greatest life expectancy. However, it must be remembered that the concepts ideal body weight” and “normal body weight” are by no means identical. Ideal body weight is a rather abstract indicator and is characteristic of only a small part (5-10%) of the population of developed countries. It depends on a number of factors, the determining factors among which are the height of a person, his gender and physique (asthenic, normosthenic and hypersthenic). concept ideal body weight cannot be interpreted too literally, because speaking of it, we mean the expected life expectancy of a large group of people, and not an accurate and reliable forecast of the longevity of a particular person.

In the case of an assessment of overweight according to ideal body weight, 60-70% of the population (including developed countries) will be diagnosed with obesity of varying degrees, which is the result of an artificially created hype around the “slender body industry” and thereby creating demand for various means of losing weight. At the same time, when calculating overweight according to the criterion of normal body weight, the prevalence of obesity in developed countries approaches 25-30%, which is true and confirmed by numerous studies. Normal body weight ranges from 5-10% relative to ideal and, as a result, is represented by a wider range of weight options. maintenance ideal body weight allows a person to achieve a good level of physical development and a high level of performance, as well as emotional and mental stability.

Calculation of ideal body weight

There are currently many ways calculation of the ideal(and normal) body mass each of which has its own advantages and disadvantages. According to P. Broca's system in the definition ideal body weight growth plays a decisive role. To calculate the indicator using this method, a person with a height of up to 155 cm needs to subtract 95 from the body length, with a height of 155 to 165 cm, subtract 100, from 166 cm to 175 subtract 105, and with a height of 175 and above - 110. However, this the formula for calculating the ideal weight, gives an approximate and very inaccurate idea of ​​\u200b\u200bthe calculated indicator, since it does not take into account the gender and body type of a person. Moreover, according to experts, calculation of ideal body weight according to the method of P. Brock is correct only in the age range from 40 to 50 years. It should be reduced by 10-12% for people aged 20-30 and increased by 5-7% for people over 50.

Soviet endocrinologist and academician G. Baranov at one time for calculation of ideal body weight recommended to use the last two digits of growth, making an amendment taking into account the structural features of the skeleton and the development of muscles (body type). In people of the athenic body type (thin bones and a narrow chest, poorly developed muscles and a wrist circumference of less than 16 cm), it is equal to the number that consists of the last two digits of growth minus 10% of this number. For normosthenics ideal body weight is equal to the number corresponding to the last two digits of growth, and for hypersthenics (wide, strong bones and a wide chest, strongly developed muscles and a wrist circumference of more than 18.5 cm), it is calculated by increasing the number consisting of the last two digits of growth by 10% .

Calculation ideal body weight according to the Devine method is made using the following formulas:

for men: BMI=50+2.3*(0.394*height-60)

for women: BMI=45.5+2.3*(0.394*height-60)

Formula for ideal mass calculation bodies according to the Robinson method looks like this:

for men: BMI \u003d 52 + 1.9 * (0.394 * height-60)

for women: BMI =49+1.7* (0.394*height-60)

Where ideal body weight (BMI) is measured in kilograms and height in centimeters.

Critical periods of change in ideal body weight

In the process of life value ideal body weight of each person is constantly changing and undergoing adjustments both in the direction of decrease and in the direction of its increase. This is an inevitable and natural process, which, nevertheless, must be kept under control. In order to prevent sudden weight gain and obesity, one should be aware of periods of increased risk of such deviations from ideal body weight.

It is necessary to carefully control the weight in children up to 2 years, as well as between 10 and 13 years, that is, before puberty. Quite often, an increase in body weight is observed immediately after the start of married life, which is explained by the banal decrease in the attention of spouses to their own figure. Pregnancy and the early postpartum period are another critical period of deviation from ideal body weight among women.

A sharp weight gain and obesity are possible after the cessation of intense sports training. Often such deviations in weight from ideal body weight occur during treatment with hormonal drugs and taking contraceptives, as well as after stopping smoking and during the onset of menopause.

In order to calculate excess or underweight, the index of ideal, or normal, body weight is used. The most common opinion is that the ideal weight for a person is the one that he had at 18 years old. However, this judgment is rather superficial. This calculator will allow you to calculate your ideal weight using parameters such as height and gender.
Calculation of normal weight for adults can be done in two ways: according to Devine or Robinson. The difference between these methods lies in the difference in the coefficients used in the formulas for the calculation.
It is worth noting that the most popular is the formula proposed by Dr. Devine in 1974. At first, this formula was used to calculate the dose of medicines for patients. Then the ideal body mass index began to be used more widely.

The formula for calculating the ideal body weight according to the Devine method (most often used for calculation):
Men: BMI=50+2.3*(0.394*height-60)
Women: BMI=45.5+2.3*(0.394*height-60)

The formula for calculating the ideal body weight according to the Robinson method:
Men: BMI=52+1.9*(0.394*height-60)
Women: BMI=49+1.7*(0.394*height-60)
BMI - ideal body weight, kg

It is known that in the USSR, a healthy weight for a woman was calculated using the simplest formula, growth minus one hundred. According to her, Baba Klava from the bench at the entrance was declared a woman with an ideal figure. Later, nutritionists slightly changed the formula - "growth minus one hundred and ten", and for ballerinas the formula "growth minus one hundred and twenty" has always worked. If such generalized data does not suit you, read on - we have collected the most interesting, relevant and reflective formulas.

Ideal Weight Calculator

Classification of body types according to Solovyov:

1. Asthenic type: less than 18 cm in men, less than 15 cm in women.
2. Normosthenic type: 18-20 cm in men, 15-17 in women.
3. Hypersthenic type: more than 20 cm in men, more than 17 cm in women.

Cooper formula

Ideal weight for a woman (kg): (height (cm) x 3.5: 2.54 - 108) x 0.453.
Ideal weight for a man (kg): (height (cm) x 4.0: 2.54 - 128) x 0.453.

Lorentz formula

Ideal weight = (height (cm) - 100) - (height (cm) - 150) / 2

For our heroine, the ideal weight will be 25 kg. State?

Kyutla Formula (Body Mass Index)

The Body Mass Index is designed to measure overweight and obesity. BMI is familiar to many.

BMI = weight (kg) : (height (m))2

BMI below 19 - underweight.

• At the age of 19-24 - BMI should be in the range from 19 to 24;
• at the age of 25-34 - BMI should be from 19 to 25;
• at the age of 35-44 - BMI should be from 19 to 26;
• at the age of 45-54 - BMI should be from 19 to 27;
• at the age of 55-64 - BMI should be from 19 to 28;
• over the age of 65 - BMI should be from 19 to 29.

Calculation example:

weight - 50 kg.

height - 1.59 m

BMI \u003d 50 / (1.59 * 1.59) \u003d 19.77 (normal BMI)

Fixed weight-height coefficient

The calculation is based on a fixed coefficient (weight in grams divided by height in centimeters). The table below is for women aged 15 to 50.

Ideal weight formula: (height in cm*coefficient)/1000

Brock's formula

It was this formula, proposed by the French physician Brock more than a hundred years ago, that was used in vulgar calculations. Brock's formula takes into account the physique: asthenic (thin), normosthenic (normal) and hypersthenic (stocky).

Ideal weight formula:

• up to 40 years: height -110
• after 40 years: growth - 100

Asthenics subtract 10%, and hypersthenics add 10%.

So our calculations are:

age - 24 years

height - 159 cm

physique - hypersthenic.

Ideal weight = 53.9 kg.

Brock-Brugsch formula

This is Brock's modified formula for people with non-standard height: less than 155 cm and more than 170 cm.

• Less than 165 cm: ideal weight = height - 100
• 165-175 cm: ideal weight = height - 105
• Over 175 cm: ideal weight = height - 110.

Egorov-Levitsky table

Attention: the table indicates the maximum weight for this height!

Maximum allowable body weight

Our exemplary woman with her weight of 50 kg with a height of 159 cm and an age of 24 years is far from the maximum. And this is good.

Many consider this table to be the most complete and balanced approach to determining the presence of overweight.

Borngardt index (1886)

It also uses chest circumference data.

Ideal weight = height * bust / 240

Robinson Formula (1983)

There is an opinion that for men it is incorrect.

For women (height in inches):

49 + 1.7 * (height - 60)

For men (height in inches):

52 + 1.9 * (height - 60)

Miller Formula (1983)

For women (height in inches):

Ideal weight = 53.1 + 1.36 * (height - 60)

For men (height in inches):

Ideal weight \u003d 56.2 + 1.41 * (height - 60)

Monnerot-Dumain formula

This formula takes into account body type, bone volume, muscle mass.

Ideal weight = height - 100 + (4 * wrist)) / 2

Kref formula

This formula takes into account age and body type.

Ideal weight \u003d (height - 100 + (age / 10)) * 0.9 * coefficient

Odds:

• Wrist less than 15 cm - coefficient 0.9
• Wrist 15-17 cm - factor 1
• Wrist more than 17 cm - coefficient 1.1.

Mohammed Formula (2010)

Ideal weight = height * height * 0.00225

According to him, the ideal weight of our heroine should be 56.88 (which is too much).

Nagler formula

A little too general, Nagler's formula does not take into account your age and current weight at all - only height and gender.

For women (note: height in inches!):

Ideal weight = 45.3 + 2.27 * (height - 60)

For men (note: height in inches!):

Humvee Formula (1964)

Online weight calculators on the Internet usually use it:

Formula for women (height in inches):

Ideal weight = 45.5 +2.2 * (height - 60)

Formula for men (height in inches):

Ideal weight = 48 + 2.7 * (height - 60)

Devin Formula (1974)

Dr. Devin invented it to correctly calculate drug doses. She entered the mass consciousness as an ideal weight calculator later and enjoyed great success. True, there are also disadvantages: for women of small stature, the weight is usually offered very little.

For women (height in inches):

Ideal weight = 45.5 + 2.3 * (height - 60)

For men (height in inches):

Ideal weight = 50 + 2.3 * (height - 60)
