What is the BMI?

BMI – Body Mass Index – is one of the most important indicators – the body mass index, which determines our physical condition based on our parameters: Height, weight and gender. Anyone can calculate their BMI, as it is the ratio of body weight in kilograms to height squared. Although this indicator can determine our physical condition, it is not enough. What counts is your body composition: the percentage of body fat, muscle quality, the amount of water in the human body, the presence of visceral fat, mineral bone mass or muscle mass. With the ketogenic diet, we help you to achieve both a correct BMI and good body composition results. The higher the BMI value, the higher the risk of diseases associated with excessive body weight. The Body Mass Index is a starting point from which we can determine whether:

we have an appropriate body weight
our diet and lifestyle are appropriate,
we belong to the risk group for diseases associated with obesity or underweight.

The BMI calculator is almost 200 years old. It was developed by the Belgian Adolphe Quetelet and is a tool that tells us whether our weight is appropriate in relation to our height. The standards allow a clear interpretation of the results, which is why it is so easy to use. The BMI calculator is a reliable indicator of the correct weight. It is sufficient to compare the ratio of the body weight in kilograms to the height given in centimetres and squared.

The BMI standards were set by the World Health Organisation. However, these standards are not appropriate for everyone. Pregnant women, children up to the age of 18, older people with decreasing muscle mass and athletes with excessive muscle mass should not use them as a guide.

BMI value ranges:

less than 16 – Hunger – is a CRITICAL condition of the body that lacks nutrients, vitamins and minerals to function properly;
16 – 16.99 – emaciation;
17 – 18.49 – underweight;
18.5 – 24.99 – normal weight – this is not only a nice number, but also an investment in our health;
25 – 29.99 – overweight;
30 – 34.99 – obesity grade I;
35 – 39.99 – obesity grade II;
over 40 – third-degree obesity – also known as morbid obesity, which appears in the ICD-10 classification as code E66. Stage III obesity is recognised as a disease.

With a correct BMI we can expect: normal blood pressure, less muscle and joint pain, a reduction in cardiovascular disease and lower blood sugar levels, which is also the aim of the ketogenic diet.

Why is the BMI so important?

To answer the question posed above: BMI is so important to us because it gives us an idea and awareness of our physical condition. We can react in time and prevent diseases such as heart attacks, type II diabetes, high blood pressure or arteriosclerosis, which are linked to malnutrition and obesity. All these diseases can shorten or limit our quality of life. It is therefore important that we react to them, even if only through an appropriate diet and physical activity.
