The degree of obesity by BMI. Formula for calculating body mass index

In many developed countries, the number of people with excess weight exceeds 50%, in addition, their numbers are steadily growing from year to year. Increasing the level of comfort, enthusiasm for fast food, lack of active physical activity on the body adversely affects the harmony of the current generation.

Problems with excess weight

Excess weight is an extra burden on the joints, blood vessels, liver, and as a consequence - diseases of the heart, arteries and veins, the musculoskeletal system. In addition, it's just plain ugly, because excess fat can spoil the most beautiful appearance by nature, and with it both self-esteem and the attitude of others. However, excessive leanness, too, never paints anyone and brings no less health problems than excess weight.

It is important to stick to the golden mean to feel healthy and sociable. Understand this will help BMI - the body mass index. Before you determine the body mass index, you need to know the exact growth and weight.

What is BMI?

How to determine the body mass index? After all, this indicator characterizes how much the person's mass coincides with the medical calculation norm. Determine the degree of obesity by BMI is simple enough, for this you need to perform simple calculations. Of the auxiliary material, you will only need a calculator.

The formula for calculating the body mass index is as follows:

• Body weight in kilograms should be divided into height in meters, ascended into a square.

How important is the connection of BMI and health

It is important to remember that maintaining your weight in an ideal framework is an important step towards maintaining your own health. Distinguish the degree of obesity in terms of body mass index. If the body mass index is less than the norm, then there is a shortage of nutrients, so necessary for the body. This increases the risk of endocrine and gastrointestinal diseases associated with insufficient nutrients in the body. The weight of such a person is less than the norm, perhaps it is to blame for too fast metabolism, diet or poor appetite. He, most likely, is disturbed by the energy balance.

What is the energy balance? The mass of the human body directly depends on the number of calories that it receives with food. On the other hand, each person spends a bit of energy on biological processes. With a normal BMI, the energy intake is equal to the energy costs, and as a result, the person has a normal weight. Energy in this case is measured in calories.

Energy and calories

Nutritionists for the development of nutrition for ideal weight use a term such as kilocalorie (kcal). Each food product has its own calorie content, that is, a certain number of kilocalories, and therefore a certain amount of energy. Caloric content of consumed food is determined by the quantity and caloric content of the products themselves. Knowing the approximate energy costs for active sports and physical activity, consumption of an approximate amount of kilocalories with food, you can adjust the amount of incoming and outgoing energy, thereby maintaining an ideal body weight.

Everyone is able to calculate the degree of obesity by BMI and find a balance between obtaining and consuming kcal, increasing physical activity or decreasing the nutritional value of their diet.

About what will tell BMI

Now more about the magnitude of BMI, which will help you get the formula for calculating the body mass index. It consists in dividing the weight by the square of the person's height.

This index can not be called an ideal characteristic of the weight of a person, but it is more important for health than the indication of weights, since each person is individual in its constitution, and its weight largely depends on the size of the skeleton. In addition, this formula is not suitable for growing organisms - children and adolescents. For athletes or people engaged in bodybuilding, it is also unacceptable. As you know, the muscles are much heavier than fat, and the inflated athlete may not correspond to the degree of obesity on the body mass index, being in excellent physical shape.

All the rest can check the state of their body by calculating their BMI. It is important to know that the risk of developing various diseases increases, the higher the body mass index.

Depending on the indicators, the classification of obesity by BMI is made:

• Low BMI;
• Normal BMI;
• excess weight;
• obesity.

Low BMI

BMI is less than 18.5 - weight below normal, the body does not get enough nutritious elements with food or energy costs are too intense. In this case, it is necessary to establish a full three meals a day, at least, meals with snacks in breaks, so that the body could replenish the missing energy reserves.

If the ratio of obesity through height and weight falls within the framework of 18.5-25, then the weight is normal from a medical point of view, although modern girls can seek to reduce it, believing that their figures are not slender enough. With a normal body mass index, it is very important to keep it at this level, eat right and lead an active healthy lifestyle.

Overweight

BMI is 25-30, so the owner of such a body is overweight. This is not very dangerous for health, but the load on all internal organs and joints is increased, which threatens with some problems, from increasing pressure to the development of diabetes and coronary artery disease. It is quite obvious that the body weight increases due to the imbalance between the arrival of energy and its consumption. But the genetic characteristics of each person are different, and with the same number of calories consumed, one can remain thin, and another rapidly gain weight. It is necessary as soon as possible to bring the weight back to normal, balancing the diet and burning more than a kilocalorie, so that energy consumption exceeds the incoming kcal.

What is the risk of obesity?

The degree of obesity in BMI gives the most accurate characterization of the appearance and health of a person. First of all, it should be understood that obesity is a disease, with all its inherent causes, the mechanism of development, clinical manifestations and methods of treatment. If the highest degree of obesity is observed in BMI, then the organism is in danger. It is necessary to lose weight immediately, better under the supervision of a doctor and a nutritionist. Refusal from the usual high-calorie food at the same time must be done gradually, as too quickly getting rid of excess kilograms, you can significantly disrupt metabolism. Nutrition should be built in such a way that at the same time all organs, including bones and joints, receive the necessary nutrients. Otherwise, the body risks to weaken its restorative forces and increase the risk of various diseases. It is necessary to grow thin, changing the quantity of consumed products, and not their quality.

In this case, you can not give up the usual food - this is also a significant stress for the body. It is necessary to gradually reduce the intake of high-calorie foods, especially fatty foods. Low-calorie food, especially vegetables, can be consumed in larger quantities, gradually replacing the fat and especially high-calorie food. For each person there should be an individual plan for dumping or gaining weight. The number of calories burned daily depends on the level of physical activity, so it is important to determine your level, because it depends on the daily need of slimming in kilocalories. The weight required for weight loss can range from 1200 to 1800 calories per day. You just need to adhere to these rules and advice, and this is the most difficult for a modern person.

What leads to overweight?

The following factors are the main reasons for the formation of extra pounds and obesity.

1. Excessive amount of high-calorie food in the diet, most often carbohydrates.
2. Features of temperament and metabolism, hereditary propensity to obesity.
3. Traditions and habits of the family, accompanied by abundant feasts.
4. Restriction of active physical activity. Unwillingness to go in for sports, passive rest.
5. Endocrine diseases. In this case, we are talking about endocrine disruptions in the metabolism that lead to obesity, often associated with congenital pathology or genetic diseases.
6. Admission of hormonal drugs, which can lead to a sharp increase in weight. After their cancellation, weight usually returns to the former.

Farewell to fat people

A healthy, active lifestyle is necessary for every person. It is not necessary to go in for sports for burning calories, it is enough to find your own version of an unbearable physical load and to deal with it regularly to fix your body mass index. A table with energy costs of calories can help in this.

You can study alone, every day doing a set of exercises or running around in the morning, and you can enroll in a wellness group of like-minded people and usefully spend time with the community. All individually, most importantly, do not give up, do not go on about age, laziness and stomach, but keep the health and beauty of your body as long as possible, despite the years.
