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 height and gender, and the obtained ideal weight value relates to these two factors.

The most famous formulas for determining the correct body weight are: BMI, Broc-Broc-Brugsh, Bernhard, Potton, Lorentz and the American Life Insurance Company formula.

All these formulas should be treated as indicative, as they do not take into account the body composition, i.e. the ratio of muscle mass to fat mass. Often, physically active people with high muscle mass are classified as overweight according to calculation formulas. The ideal weight formulas are therefore the most reliable for people with an average body build.

Based on the formulas below, we obtain results with certain discrepancies, therefore they should not be the only determinant of a he althy body weight. An important factor is the figure, body appearance, well-being, and most of all body fat, which is the main indicator of normal body weight and can be measured by a simple method of electrical bioimpedance.

Let's take a look atformulas used to calculate the ideal body weight .

1. Body Mass Index (BMI)

BMI is the most commonly used indicator of proper body mass. It shows the ranges of underweight, normal weight, overweight and obesity. We count it according to the formula:

BMI=body weight [kg] / height [m]2(check your BMI in the calculator)

The BMI ranges are as follows:

  • underweight: BMI<18,5
  • correct weight: BMI 18.5-24.9
  • 1st degree 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
  • III degree obesity (fatal):BMI 40-49.9
  • 4th degree obesity (extreme) BMI>50

If your BMI is in the range of 18.5-24.9, this is a good weight.

2. Broca pattern

During the research conducted by the French physician Pierre Broc on soldiers in the nineteenth century, a relationship was noticed, according to which the average body weight of the respondents was the height value in cm - 100. Currently, this formula is modified taking into account sex. It is assumed that the Broc formula is reliable for people with a height of not less than 160 cm and not more than 190 cm.

  • Broc's formula for women correct body weight [kg]=(height [cm] - 100) x 0.85
  • Broc's formula for men due body weight [kg]=(height [cm] - 100) x 0.90

3. Broca-Brugsha formula

The Broca-Brugsh index is similar to the basic Broc formula. The amount that is subtracted from height to determine weight varies depending on how tall the person is.

  • Broca-Brugsh formula for people with a height of 155-164 cm correct body weight [kg]=(height [cm] - 100)
  • Broca-Brugsh formula for people with a height of 165-175 cm correct body weight [kg]=(height [cm] - 105)
  • Broca-Brugsh formula for people with a height of 176-190 cm due body weight [kg]=(height [cm] - 110)

4. Bernhard's formula

In Bernhard's formula, apart from height, the circumference of the chest is also taken into account. There is no gender distinction, and female chest circumference should be measured just below the bust.

  • due weight [kg]=height [cm] x chest circumference [cm] / 240

5. Potton's formula

The formula can be used for people taller than 150 cm.

  • Potton formula for women correct body weight [kg]=height [cm] - 100 - (height [cm] - 100) / 10
  • Potton formula for men correct body weight [kg]=height [cm] - 100 - (height [cm] - 100) / 20

6. Lorentz formula

The formula can be used for people taller than 150 cm.

  • Lorentz formula for women correct body weight [kg]=height [cm] - 100 - 0.5 x (height [cm] - 150)
  • Lorentz formula for men correct body weight [kg]=height [cm] - 100 - 0.25 x (height[cm] - 150)

7. American Life Insurance Company template

The formula can be used for people taller than 150 cm.

  • due weight [kg]=50 + 0.75 x (height [cm] - 150)

How to weigh yourself correctly?

  • Time - you need to weigh yourself at the same time, preferably in the morning, in only your underwear or naked, on an empty stomach and after defecation. Then the body weight is least changed by external factors.
  • Frequency - weigh yourself once a week. Daily weighing can be frustrating because body weight varies significantly depending on the amount of metabolic water retained in the body and may be different every day - not always in line with the expectations of a slimming person.
  • Equipment - always use the same weight. Thus, the measurement is burdened with the same error.
  • Place - always weigh yourself in the same place. The weight indication may be slightly different depending on whether you place it on tiles or on a panel floor, as the hardness of the substrate changes.
  • Measure your circumference - when you start losing weight, check your waist, navel, hip and thigh circumference. Check them every 3-4 weeks. This is a very good indicator of progress in weight loss.
