Ideal Body Weight and Health by WHO

Weight Loss calories

At all times, people wondered how to achieve perfection. The World Health Organization turned out well to resolve this issue at least in the perfect body weight for a person.

What Is WHO?

WHO is an abbreviation of the World Health Organization. It was founded in 1948 in Geneva, Switzerland. It consists of 194 countries and aims to resolve the health subjects of the humanity of the globe. 

How to Define a BMI?

To calculate your ideal body weight, you need to be aware of your BMI. BMI (body mass index) is a measurement that determines the degree to which a person’s height corresponds to his/her mass. While implementing BMI to the adequate formula, you may deduce about insufficient, normal, or overweight.

WHO has elaborated the formula to define the ideal weight for men and women. It looks like:

BMI – Weight (kg or Ibs) / (Height (m or in) *2

For example, if your weight is 80 kg, and your height is 1,80 m, your BMI is 80/ 1,80*2 = 22,2.

According to the WHO, BMI means:

  • Less than 16 – a strong leanness
  • From 16 to 16,9 – a leanness
  • From 17 to 18,4 – underweight
  • From 18,5 to 24,9 – normal (ideal) weight
  • From 25 to 29,9 – fatness
  • Over than 30 – strong obesity

To make it easier for users to calculate their measurements, there are a lot of automatic programs. There, you can count your index within seconds and track your BMI Chart.

Misses of the BMI

BMI is an approximate value, and it cannot determine with 100% accuracy whether a person’s weight is healthy. This is a very simple form of measurement that takes only basic units; so, this method cannot be considered the only correct meter. 

BMI does not take into account factors such as: 

  • waist and hips
  • body fat distribution
  • percentage of muscle and bone mass

For example, professional athletes have a big bodyweight but low body fat. Nevertheless, their BMI will be equally high as in obese people. 

Alternative Measurements

WHR. If you want to check your body for possible cardiovascular diseases, measure your WHR (waist-hip ratio). How to make it? Measure your waist at the narrowest point and divide by your hips at the widest point. For example, if your waist is 70 cm, and your hips are 110 cm, your WHR is 70/110 = 0,63.

According to WHO, these data can be interpreted as:

  • Lower than 0,9 (men) and 0,8 (women) – the minimal risk of cardiovascular diseases
  • From 0,91 to 0,99 (men) and 0,81 to 0,89 (women) –middle risk
  • Over 1,0 (men)  and 0,9 (women) – the risk of getting cardiovascular diseases is high

WtHR (waist-to-height ratio) excellently predicts the risk of heart disease, diabetes mellitus, and mortality. To calculate WtHR, you have to divide your waste on your height. The health index should be less than 0,5. For example, if your waste is 70 cm, and your height is 170, WtHR = 70/170 = 0,41.


None of the approaches can give you a complete picture of your body state. To obtain the most precise result, you should combine them all. Eat well, go in for sports, and be healthy!
