Ideal weight

Normal weight or ideal weight – what is the difference? These two terms are often used interchangeably, but there is a difference between them. Normal weight indicates the range within which weight is not considered a health risk. For example, the body mass index (BMI) can be used to define normal weight. In contrast, ideal weight usually follows aesthetic requirements and purely personal goals.

For many people, the ideal weight – especially these days – is often below normal weight and can be dangerous to health. Therefore, the ideal weight is not necessarily the right weight to determine the weight that is comfortable for you and your health.

The ideal weight indicates a minimum weight; readings below indicate underweight.

Normal weight is the weight that is standard for people of their height, anything more than that is overweight.

Ideal weight: Conclusions

It is believed that the ideal weight is the one you had when you were 18. It is desirable to keep it all your life. But if in the past 15-20 years or more you have fallen away from the ideal, you should not strive to return to it at any cost. After all, every 10 years of life the body’s energy expenditure decreases by about 10%.

Accordingly for every 10 years we add about 10% (5-7 kg): first from the ideal weight, later from the one that we have. It is necessary to lose fat carefully, focusing on the same 10%, but for one year. In addition, it is better not to strive for an eighteen-year-old weight, but to calculate their new ideal by one of the medical formulas.

There are many formulas for calculating weight (indices), and they are adjusted all the time. A little excursion into the world of formulas.

In 1965, according to M.N. Egorov, 4 degrees of obesity were defined

I degree – excess weight by 20-29% above the norm;

Grade II – excess body weight from 30 to 49%;

3rd degree – from 50 to 99% overweight;

Degree IV – body weight 100 percent or more above the normal range.

Mankind fights excess weight with the help of diets, sports and proper drinking regime.

Broca’s formula (index)

The normal weight in kg = a person’s height in cm – 100 cm for people between 155 and 165 dm.

At a height of 165 to 175 cm – 105 cm;

At a height of 175-185 cm – 110 dm.

This method did not take into account either age or type of physique.

Brightman’s formula (index)

Height in cm x 0.7 – 50 = result in kg.

Borngardt’s formula (index)

Height in cm x chest circumference in cm and divide by 240 = result in kg.

Garrow Index (Body Mass Index)

Divide your body weight by your height squared (in meters).

Normal BMI = 20-24.9;

Grade I obesity = 25-29.9

Grade II obesity = 30-49;

Grade III obesity over 40.

To determine body fat content in women, use the formula

1.218 x Garrow index = 10.13%;

in men

1.48 x Garrow index = 7.0%.

Obesity with adipose tissue content higher than normal by 20-25% in women; and by 15-20% in men.

It should be noted that an increase in body weight is possible due to individual features of the skeleton and with an increase in muscle tissue in persons engaged in heavy labor and athletes.

But in any case, visceral fat must go!

This fat is an important factor in calculating the waist-to-hip ratio. The higher the value, the more belly fat you have.

Abdominal fat is metabolically active and therefore can increase the risk of cardiovascular disease and some cancers.

There are now new formulas for calculating the ideal weight as…

Body Mass Index < BMI>

To calculate the lower ideal weight, you need the BMI for men 20 years old and for women 19 years old.

For the upper ideal weight, you need a BMI for men of 25 and a BMI of 24 for women. Height is given in meters.

Ideal weight for men (lower value) = Height² x 20

Ideal weight for men (upper value) = height² x 25

Ideal weight of a woman (lower value) = height² x 19

The ideal weight of a woman (upper value) = height² x 24

The result looks like this

BMI under 18.5: Underweight

BMI 18.5 to 24.9: Normal weight

BMI 25 to 29.9: (slightly) overweight

BMI 30 to 34.9: Grade I overweight

BMI 35 to 39.9: Grade II overweight

BMI 40 to 40: Grade III overweight

This approach was further optimized with the so-called Creff formula.

The Creff formula: What’s different from BMI?

The Creff formula takes into account your personal body type. Depending on what your body type and physique is, the calculation adapts to your personal data. This way, your ideal weight can be calculated even more accurately.

Calculate your ideal weight with the Creff formula.

The general Creff formula, which works best for people of average build and average height:

– [(height in cm – 100) + (age / 10)] x 0.9 = personal ideal weight


– You are 170 cm tall and 30 years old – so your calculation looks like this:

– [(170 – 100) + (30/10)] x 0.9 = 65.7 kg – your personal ideal weight

The formula is slightly modified in each case:

  1. Kreff’s formula for people of short stature and slim build

– [(height in cm – 100) + (age / 10)] x 0.9 x 0.9

  1. Kreff’s formula for people with a fairly sturdy build

– [(height in cm – 100) + (age / 10)] x 0.9 x 1.1

Et voila – you already know exactly what weight you should be targeting when dieting.

If you are already in your ideal weight range, you only need to maintain this.

Weight fluctuations of two to three pounds are perfectly normal.

Because of the cycle, hormones can cause water to build up in the body, resulting in a slight weight gain; but constipation or increased physical activity can also lead to these natural weight fluctuations.

Egorov-Levitsky chart.

There are no formulas. The author offers a table.

Weigh yourself and compare the data with the table.

It’s not your ideal weight, it’s your maximum weight!

Lorenz’s dream.

A woman’s ideal weight = (height in centimeters – 100) – (height in centimeters – 150) / 2.

Example: The ideal weight of a woman who is 165 cm tall =(165 – 100) – (165 – 150) / 2 = 65 – 15/2 = 57.5. The ideal weight is 57.5 kg!

The formula does not work for men and women over 175 cm.

Waist to hip ratio

Being overweight is not just about being overweight. Because – you already know – that especially fat deposits on the belly and around the waist increase the risk of cardiovascular and other metabolic diseases.

Thus, the “apple type” with belly fat has a higher risk of disease than the “pear-shaped” type, which “stores” fat on the hips and buttocks.

Calculating the waist-to-hip ratio is simple: waist circumference : waist circumference. Ideally, this ratio should be less than 1.0 for men and less than 0.85 for women.

To determine an increased health risk, all you need to do is measure your waist circumference. This should be no more than 88 cm for a woman and no more than 102 cm for a man.

Alternatively, you can also calculate your waist-to-height ratio. This value should be less than 0.5 for those under the age of 40 and 0.6 for those over 50.

Ideal weight: conclusions

There are many methods for determining underweight, normal weight, ideal weight and obesity.

Different formulas should be used depending on your height, build, fitness and goals.

But already the waist-to-hip ratio and waist circumference size can help determine the weight at which you are least at risk for health problems.

And, of course, aside from all the numbers, the most important thing is that you feel comfortable in your body.
