How to Calculate Body Mass Index and Maintain a Healthy Weight

Body mass index (BMI) is one of the important indicators of health; only an objective assessment can lend a helping hand and prevent you from pushing yourself to the extreme. You can calculate it by dividing your weight (kg) by your height (m) squared. Or use the BMI calculator, which will calculate everything in a few seconds!

Obesity and anorexia are two extremes that bring with them enormous difficulties both for human health and for his social activity. The problem does not arise overnight, but gains momentum gradually. With targeted monitoring of one's own weight, any person has a chance to prevent disease before it takes root. This is done very easily - periodically you need to check if the parameters of the figure correspond to the norm.

What does body mass index mean?

BMI is a medical term used to measure weight according to height. Its meaning must necessarily be considered taking into account the physique, gender, and age of a person. Fat and muscle tissue in men and women are distributed in different proportions, plus the type of figure imposes its own edits. Accordingly, everyone will have their own ideal index. Subjectively, it can be difficult to both determine the real picture and accept what you see. Plus, this applies to anorexia, the pursuit of a model appearance, attempts to push your body into a far-fetched ideal, almost always turn a blind eye to the truth. It’s the same with overweight – depression, overeating as an escape from stress or a complex of self-dislike will not allow you to just stop. And only an objective assessment can lend a helping hand and will not allow oneself to be driven to extremes.

Eat a balanced diet

The body must receive the required amount of proteins, fats and complex carbohydrates (BCC). Eat fish and seafood, meat, eggs and dairy products, nuts, cereals and legumes, vegetable oils, green vegetables.

But the body needs proteins, fats and carbohydrates in different quantities. In addition, proteins are divided into complete and incomplete, fats into saturated and unsaturated. Their proportions in the daily diet also differ...

It's easy to get confused about this, especially if you're not very knowledgeable about healthy eating. What foods to choose, how to correctly calculate the calorie content of dishes, what to cook so as not to sit on one salad all day? There are really a lot of questions.

Online calculator for calculating body mass index

Don’t know how to determine and calculate BMI yourself? Our online calculator allows you to calculate and find out your body mass index in a matter of seconds; to do this, you just need to indicate your real parameters. The calculation takes place in a couple of moments. This definition allows you to find out what weight category you belong to (whether there is a threat to your health). Based on this indicator, it will be possible to make plans for further actions: adjustments to diet, amount of physical activity, seeking medical help.

IMPORTANT! The online counter is not universal. It is not suitable for bodybuilders, during pregnancy, or for measuring the body of newborns.

How to determine the correct inputs?

How to calculate your real weight - be sure to weigh yourself in the morning, after toilet procedures, before meals, without heavy clothing, barefoot.

How to calculate height - during the day it can fluctuate within 0.5 - 2 cm, so it is also measured in the morning.

You can evaluate the results using the tables presented below. In them you can find:

• normal index;
• below normal;
• overweight index;
• stages of obesity.

Formula for self-determination of the index

How to find out BMI if you can’t use an online calculator? Using a simple mathematical expression - a calculation formula for independently determining BMI:

Body Mass Index = Weight (kg)/Height² (m)

Interpretation of indicators based on WHO recommendations:

• up to 16 – pronounced weight deficiency;
• 16 – 17.9 – insufficient body weight;
• 18 – 24.9 – index norm;
• 25 – 29.9 – overweight;
• 30 – 34.9 – 1st degree obesity;
• 35 – 39.9 – 2nd degree obesity;
• over 40 – 3rd degree obesity.

The accumulation of fat in the body is not a pathology in itself. This is a natural process of forming reserves for the future, especially for women who are called upon to bear offspring, and therefore provide the fetus with a set of necessary substances. But everything has a limit.

If the calculation showed you points 16-17.9 and 25-29.9, there is no need to panic. It is enough to choose the right diet, if possible, resort to strength training in the gym, and think about the reasons.

The concept of UTI and reasons for its use

The coefficient ratio is used in medicine to identify insufficient or excess weight. Deviation from generally accepted standards leads to the formation of pathologies of the cardiovascular system, joints, and respiratory organs. Body mass index values ​​do not differ by gender.

Continuous weight gain poses health risks. But UTI rates are not absolute for all people - small nuances are associated with sports, race, and age. The ratio is not considered an ideal tool for diagnostic testing. When doing weightlifting, the data does not correspond to the average statistical standards; they are designed for the average patient with small muscles.

When conducting an inspection, specialists pay attention to:

• on the volume of the skin fold - helps to identify the percentage of fat mass contained;
• features of the diet, the presence of regular motor and physical activity;
• genetic predisposition to obesity or anorexia.

In addition to BMI, secondary research is required. High levels are not always a harbinger of excess kilograms; their danger to life and health is determined by consultation with a doctor.

Obesity or overweight index

First degree obesity is characterized by an index range of 30-34.9 points. Despite the outward inconspicuousness and familiarity of this condition, the level of complications to which it leads is quite high. These include diseases such as diabetes, atherosclerosis, and cardiac dysfunction.

The second degree of obesity corresponds to an indicator of 35-39.9 units. Here it’s worth sounding the alarm and seeking help from specialists, since the risk of the most popular diseases triples.

The most dangerous indicator for health, vital activity, and eventually life itself, is a result of over 40 points. At this stage of obesity, simple diets can no longer help yourself. The way out of the crisis should be under the supervision of doctors, be gentle, gradual, since sudden weight loss can be no less dangerous than maintaining excess weight.

Interestingly, taking into account body type, there are two types of obesity:

• according to the male type, then fat accumulates from the abdomen and above;
• in the female type, the thighs and buttocks are most affected.

conclusions

Finding a problem leads to finding the most effective solution. An experienced psychologist can greatly help you with this. He will determine the right motivation and teach you how to fight complexes and bad habits. The attending physician will prescribe a period of rehabilitation therapy, and the cosmetologist will help cope with the loss of elasticity and smoothness of the skin after active weight loss.

The next difficult stage for many patients is complete adaptation to society. People have become unaccustomed to full-fledged social, family and work connections. Friends, relatives, and colleagues should help restore them with the least psychological loss.

Use a set of weapons that are very dangerous for him to fight Sly Fat:

• leisure,
• physical work and sports activities,
• moderate, balanced diet,
• constant contacts with doctors, nutritionists and psychologists.

Eating more fruit can improve bone density.

Correct! Wrong!

Consuming foods with plenty of bioavailable calcium improves bone density. Fruits generally do not contain much calcium.

Excess protein accumulates in the muscles, causing them to increase.

Correct! Wrong!

Once the need for protein and energy has been met, excess amino acids are converted to acetyl-CoA, from which they are converted into fatty acids and stored in adipocytes. Therefore, excess protein will not be converted into muscle.

Body mass index for women

As measurements show, the ideal index varies depending on gender, which is associated with the natural characteristics of the bone structure and figure. In women, the normal index is slightly lower than in men. For girls it will be even lower.

You can calculate the required value using an online calculator or calculate it using a formula.

BMI table for women

Body mass index for men

A man's BMI can be determined, just like a woman's, by calculating it using the formula by dividing the total weight by the square of height. The norm will be slightly higher.

You can easily find out online whether you belong to a risk group using the table:

The criteria for assessing the indicators are described in detail above. But let us remember - with good physical training, training in the gym, passion for sports, which leads to an increase in muscle mass. The index will be higher than ideal, since the weight of muscles is greater than that of fat deposits.

BMI for children and adolescents

The problem of excess weight, unfortunately, is relevant not only for adults, but also for the younger generation. It is especially pronounced in families where this trend affected both parents. It is dangerous to turn a blind eye to this; a child’s body is more vulnerable and is just being formed.

The load on the internal organs is higher than normal due to the pressure of fatty deposits, the need of the heart to pump blood more intensively, and the liver to more intensively cleanse it of toxins - will ultimately lead to incurable diseases. Don't forget this.

It is necessary to calculate the body mass index for children and adolescents taking into account their age separately. To obtain correct results, in particular the norms for adolescents, gender and age are included in the calculation, since the young body develops rapidly and gender has a huge influence.

A subjective way of assessment is to compare the external parameters of your child and his peers. But it is better to use an online calculator or formula and check the result against the table to determine the index.

The development scale for boys and girls is different, as evidenced by the figures in the tables, where the deviation from the predicted norm is expressed in %.

In case of strong deviations from the norm for adolescents (+\-), you should contact your pediatrician to clarify the causes and possible consequences.

Egorov-Levitsky table

This method is very easy to use! You don’t need to calculate anything, just step on the scales and then compare the result with the data in the table.

Maximum permissible body weight

It is worth noting that here we are talking about the maximum allowable weight for each age.

Body mass index based on age

The last, but no less painful point is the age assessment. In youth, a person is more active, emotional, and pays closer attention to his appearance. By the age of 40, most people reduce the pace of life and physical activity, which is quite natural and is reflected in the figure. The indicator itself should be calculated using an online calculator; the table is used to estimate the ideal index:

As you can see, over the years it increases slightly, which is absolutely normal and should be taken into account.

Remember - regularly determining your BMI will allow you to take timely measures to improve your health, avoid many diseases, and improve your appearance.

Are there any restrictions

It is recommended to use this method of calculation in adulthood. Young and old people should use this technique with caution as it has been statistically proven that they have a lower BMI. This means you shouldn’t navigate by it.

Another reason for mistrust of this technique is the inconsistency of the calculation results using different formulas.

For example, according to WHO criteria, most people are obese.
However, when using a formula containing the person's age and gender, the results are much closer to the actual results. Additionally, you may be asked to indicate your wrist circumference. To do this you need to use a measuring tape. It is fixed just above the wrist. The resulting value is entered into a separate field on the resource website, which will allow you to calculate BMI. No actions are taken to calculate this indicator independently. Everything is calculated by the program.

The calculator itself is at the very beginning of this page.
