Recommendations for women

1. Underweight. People can become underweight for several reasons - congenital constitution (thin physique), insufficient nutrition (unbalanced diet), hormonal disorders, too fast metabolism, and hyperglycemia - the body’s ability to absorb glucose at a high speed. Hormonal imbalances should be corrected by an endocrinologist. Other violations require independent correction of dietary errors: increase the amount of carbohydrates and fats. Much more energy must be absorbed than such an organism expends, although this happens quite quickly. The consumption of simple carbohydrates is not prohibited. Loads should be aimed at increasing muscle mass; aerobic training will only slow down the process of gaining body weight.
2. Normal weight. The happy owners of the norm should only follow in the same spirit. With a balanced diet and moderate physical activity, body weight will be maintained. Overeating may increase your BMI, so you should not increase your caloric intake to avoid resorting to diets later.
3. Overweight. Those whose index has exceeded 25 should reconsider their lifestyle. First, review your diet. If the menu is dominated by carbohydrates (flour, sweets), you should reduce their consumption to a minimum. Eliminate sugary foods and increase protein in your diet. Secondly, analyze your physical activity. With a sedentary lifestyle, fats are absorbed especially well, since the body does not spend energy, which means it accumulates subcutaneous fat. Start doing physical activity, but watch the condition of your joints ; if you are overweight, your joints are already subject to stress.
4. Obesity. One of the causes of obesity is not only an excess of calories and a sedentary lifestyle, but also hormonal disorders. Hormonal imbalances, such as too much female hormones and too little male hormones, can lead to the accumulation of excess fat, not to mention diseases such as diabetes. This problem can only be solved with the help of hormonal therapy. If there are no violations, it is necessary to follow the measures as in the recommendations for overweight. In any case, reduce the overall calorie content of your diet, remove simple carbohydrates (sweets, and even fruits), and walk more. And don't eat 3-4 hours before bedtime .
5. Severe obesity. If you are severely obese, you should consult a doctor. Rather, this degree of obesity is not simply caused by diet. It is necessary to take tests for hormones and identify the content of enzymes, the possible absence of which makes it impossible to digest certain nutrients - fats and carbohydrates. Otherwise, proper nutrition and walking will not hurt.

BOO based on lean body mass. Body fat percentage

The disadvantage of both of the above formulas is that they do not take into account the percentage of muscle in the body, although, as is known, it is muscle mass that directly affects the metabolic rate.

Therefore, these formulas are well suited for people of average build. However, in some cases it is more correct to use the Ketch-McArdle

, which is based solely on lean body mass.

To calculate your lean body mass, you must first determine your body fat percentage. To do this, you need to specify additional initial data.

After filling in all fields, click the calculate button.

Results:

Body fat percentage: -

Fat mass: —

Basal metabolic rate: —

Daily calorie requirement: -

Recommendations for men

1. Underweight. Men also have a number of reasons for being underweight - hormonal imbalances, hyperglycemia, accelerated metabolism and lack of nutrition. With high intensive loads and work associated with physical labor, you should ensure an excess of calories in the diet, exceeding the amount of carbohydrates over proteins and fats. You need to eat often, at least 6 times a day. Workouts should last no more than an hour, perform loads aimed at gaining muscle mass.
2. Normal weight. With proper nutrition and exercise, maintain your usual lifestyle without significantly changing anything in your diet or exercise.
3. Overweight. A common cause of excess weight in men is not only an addiction to food, but also to drinks such as beer. The content of phytoestrogens in beer increases the production of female hormones, which leads to the accumulation of female-type fat (belly and thighs). In any case, there is the possibility of hormonal imbalance, in the direction of increasing estrogen and decreasing androgens. If the cause is poor nutrition, eliminate foods with a high glycemic index from your diet and move more.
4. Obesity. In men, as in women, the cause of obesity can be endocrine system disorders, as well as an excess of calories in the diet. Overeating can also be negatively affected by socio-psychological factors. Therefore, you should exclude all diseases and switch to a low-carbohydrate diet high in protein and fiber.
5. Severe obesity. You need to urgently consult an endocrinologist or gastroenterologist. You can also take measures to prevent the possibility of gaining even more weight, which are recommended for overweight and obesity.

Weight calculator

What specific weight is ideal for me?

The calculator calculates the ideal weight range for you based on your height.
From this range you are free to choose any specific weight, depending on your preferences, beliefs and requirements for your figure. For example, adherents of a model figure tend to keep their weight at the lower limit. If your priority is health and healthy life expectancy, then your ideal weight is calculated based on medical statistics. In this case, the optimal weight is calculated based on a BMI of 23.

Can the assessment received be trusted?

Yes. Adult weight estimates are based on the results of authoritative studies from the World Health Organization (WHO). The weight of children and adolescents from birth to 18 years of age is assessed using a separate special method, also developed by WHO.

Why is gender not taken into account?

BMI assessment of adults is carried out in the same way for both men and women - this is justified by the results of statistical studies. At the same time, when assessing the weight of children and adolescents, gender and age are of fundamental importance.

Some other weight calculator gives a different result. What to believe?

There are a huge number of calculators designed to give weight estimates based on height and gender. But their formulas, as a rule, were developed in the last century by individuals or teams based on criteria that are unknown to you or do not suit you (for example, formulas for evaluating athletes).

The WHO recommendations used in this calculator were developed for ordinary modern people, taking into account the conditions of modern life, medical advances and based on recent observations of the population of all continents of the planet. Therefore, we trust only this technique.

I believe the result should be different.

The assessment is made solely on the basis of the height and weight data you provide (as well as age and gender for children). If you receive unexpected results, please double-check all entered data. Also, make sure that you do not fall into any of the categories of people whose weight is not assessed through the body mass index.

My result is underweight, but I want to lose more weight

There is nothing unusual in this; many professional models, dancers, and ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a nutritionist and endocrinologist, so as not to harm your health, if it means something to you.

Please note that most people's bodies are not able to fully function in a state of underweight. And only a few, due to the characteristics of genetics (or disease, ecology, lifestyle), can live comfortably with a deficit of body weight: without risk to health and without experiencing malaise, dizziness and constant hunger.

My result is normal, but I consider myself fat (or thin)

If you have concerns about your figure, we recommend taking up fitness after consulting with a good nutritionist.

Please note that some elements of the figure are practically impossible to correct only with the help of fitness, exercise, diet, or a combination of these. Your goals should be analyzed by an experienced doctor to assess their reality, consequences and prescribe only the right procedures.

My result is pre-obesity (or obesity), but I don’t agree with it

If you are an athlete (or an amateur weightlifter) with increased muscle mass, then weight assessment by BMI is simply not intended for you (this is mentioned in the explanation). In any case, for an accurate individual weight assessment, contact a nutritionist - only in this case will you receive an authoritative result with a doctor’s seal.

Why am I considered too thin or fat even though my weight is normal?

Pay attention to the personalities and weight of the people who bother you. As a rule, they judge solely by themselves: subjectively. Overweight people always consider thin people to be skinny, and thin people always consider overweight people to be fat, moreover, both of them can have a weight within the healthy norm. Take into account social factors: try to exclude, suppress or ignore those judgments addressed to you that are based on ignorance, envy or personal hostility. Only an objective assessment of BMI, which clearly indicates the norm, excess or deficiency of mass, is worthy of trust; and trust your concerns about your figure only to supportive people in your weight category, or better yet, to an experienced nutritionist.

How to calculate body mass index (BMI)?

It is necessary to divide the weight indicated in kilograms by the square of the height indicated in meters. For example, with a height of 178 cm and a weight of 69 kg, the calculation will be as follows: BMI = 69 / (1.78 * 1.78) = 21.78
