How much should I weigh? If you often ask yourself this question, you’ve come to the right place. There are several ways to calculate your ideal body weight. Some are less, others more complicated. Typically, the calculation formula takes into account the height and sex, and the obtained ideal weight value refers to these two factors. The most well-known patterns for determining normal body mass include BMI, the Broc, Broc-Brugsh, Bernhard, Potton, Lorentz and American Society of Life Insurance.
All these patterns should, however, be treated as approximate, because they do not take into account the composition of the body, i.e. the ratio of muscle mass to body fat. Often, physically active people with high muscle mass according to calculation formulas are classified as overweight people. Patterns for ideal weight are therefore the most reliable for people with average body size. Based on the following formulas, we obtain results with certain discrepancies, therefore they should not be the only determinant of normal body mass. An important factor is the silhouette, body appearance, well-being, and above all the body fat content, which is the main indicator of normal body weight and can be measured by simple electrical bioimpedance method.

Let’s look at the formulas used to calculate the ideal body weight.
1. Body Mass Index (BMI)
BMI is the most frequently used indicator of proper body mass. It presents ranges of underweight, normal weight, overweight and obesity. We count it according to the pattern
BMI = body mass kg / m2 increase
The BMI ranges look as follows
underweight BMI <18.5
normal weight BMI 18.5-24.9
I grade overweight BMI 25-26,9
2nd degree overweight BMI 27-29.9
1st degree obesity BMI 30-34,9
2nd degree obesity BMI 35-39.9
3rd degree obesity (fatal) BMI 40-49.9
4th degree obesity (extreme) BMI> 50
If your BMI is between 18.5 and 24.9, it means your body weight.
2. Broc pattern
During the research conducted by the French doctor Pierre Broc on soldiers in the nineteenth century, a relationship was found, according to which the average body weight of the subjects was the value of the increase in cm – 100. Currently, the modification of this formula with regard to gender is used. It is assumed that the Broca pattern is authoritative for people with a height of not less than 160 cm and not more than 190 cm.
Broca pattern for women
due to body weight kg = (height cm – 100) x 0.85
Broca pattern for men
due to body weight kg = (height cm – 100) x 0.90

3. Broc-Brugsh pattern
The Broca-Brugsh index is similar to the basic Broca pattern. The value subtracted from the height to determine the weight varies depending on the growth range in which the person is located.
Broca-Brugsh pattern for people with a height of 155-164 cm
due to body weight kg = (height cm – 100)
Broc-Brugsh pattern for people with a height of 165-175 cm
due to body weight kg = (height cm – 105)
Broc-Brugsh pattern for people 176-190 cm tall
due to body weight kg = (height cm – 110)
4. Bernhard’s formula
In the Bernhard formula, apart from the growth, the chest circumference is also taken into account. There is no distinction related to sex, while the circumference of the chest in women should be measured just below the bust.
due to body weight kg = height cm x chest circumference cm / 240
5. Potton’s pattern
The pattern can be used for people over 150 cm tall.
Potton pattern for women
due to body weight kg = height cm – 100 – (height cm – 100) / 10
Potton pattern for men
due to body weight kg = height cm – 100 – (height cm – 100) / 20
How to weigh correctly?
Time – you should weigh yourself at the same time, preferably in the morning, in underwear or naked, on an empty stomach and after emptying. Then the body mass is least affected by external factors.
Frequency – check once a week. Daily weighting can cause frustration, because the weight of the body varies significantly depending on the amount of metabolic water retained in the body and may be different every day – not always consistent with the expectations of a slimming person.
Equipment – always use the same weight. The measurement is thus burdened with the same error.
Place – always stay in the same place. The indication of the weight may be slightly different depending on whether you put it on the tiles or on the floor of the panels, because the hardness of the substrate changes.
Measure circuits – at the beginning of slimming, check your waist circumference, at the height of the navel, on the hips and in the thigh. Control them every 3-4 weeks. This is a very good indicator of progress in weight loss.
