Some girls lead themselves to fainting with crazy diets, focusing on bony models on TV, others are not at all worried about the problem of excess weight. And very few people are really interested in – and what should it be, is it the norm of my weight?
And to take an interest on this topic is not only to know “how much to throw off”, but first of all, to understand your own organism – it is easier to prevent the problem, as they say.

weight standards calculation women by age and growth
Modern Nutrition now offers many ways (of course, approximate rather than accurate to a gram) of the definition of its weight standards. One of the most popular is the calculation, which is carried out based on the growth and age of the lady.
How to gain weight to a very thin girl – a diet for weight gain
Everyone knows that over time, weight can gradually increase. And this is considered the norm. That is, those “extra” centimeters, in fact, can be completely and not superfluous. Therefore
use for counting a certain formula:
50 + 0.75 (P – 150) + (B – 20) 4 = your weight norm
In this case, “B” – it’s your age (note – full years), and “P” – is, respectively, growth.
Quetelet index will calculate the ideal weight
Through BMI (note -. Body mass index), it is possible to draw conclusions about the lack of weight gain or obesity beginning of the process.
The calculation for this scheme is usually carried out for adults of both sexes who have already reached the age of 18 and have not yet crossed the age of 65 years .
It is worth noting that it is possible to get a false result if the “researcher” is an elderly person or an adolescent, a nursing mother or a future mother, or an athlete.
How to find this very index?
The formula is simple:
In: (P) 2 = BMI. In this case, “B” is your weight, and “P” is the height (squared). For example, a girl with a height of 173 cm has a weight of 52 kg. Using the formula, we get the following result: 52 kg: (1.73 x 1.73) = 17.9 (BMI).
We estimate the result:
- BMI <17,5 – anorexia (urgently to the doctor).
- BMI = 17,5-18,5 – underweight (not reaching the norm, it’s time to recover).
- BMI = 19-23 (at the age of 18-25 years) – the norm.
- BMI = 20-26 (for people over 25 years of age) is the norm.
- BMI = 23-27.5 (at the age of 18-25 years) – weight is more than normal (it’s time to take care of yourself).
- BMI = 26-28 (when over the age of 25 years) – overweight.
- BMI = 27.5-30 (18-25 years) or 28-31 (over 25 years) – obesity of the 1 st degree.
- BMI = 30-35 (18-25 years) or 31-36 (over 25 years) – obesity of the second degree.
- BMI = 35-40 (18-25 years) or 36-41 (over 25 years) – obesity of the third degree.
- BMI exceeds 40 (18-25 years) or 41 (for people over 25) – obesity of the 4th degree.
As you can see from the table, independently – 19 years old or already “knocked” 40, but the lower limit is uniform for any age (within 18-65 years, of course).
That is, if a girl with a BMI of 17, from morning to night, discards “extra pounds”, then, in addition to a nutritionist, she would not be hindered by a specialist in the correction of the psyche.
How to determine your normal weight by body volume?
If your weight is “normal” in most of the indicators, but still the insignificant fullness is reflected in the mirror and prevents you from quietly eating at night, you can use another method.
If the previous method shows the presence / absence of excess fat, then using this formula, you can determine the ideality of the figure, based on the waist circumference (note – we measure at the level of the navel).
P (waist in cm): V (volume of the buttocks, in cm) = Value of formula, of which the following look
- Women rate: 0,65 – 0,85.
- Men rate: 0,85 – 1.
Nagler formula for calculating the norm of its own weight
Using this formula, one can calculate the ideal ratio of its height and weight:
- At 152, 4 cm of your height account for 45 kg.
- For every inch (note – inch is equal to 2.54 cm) beyond that – another 900 grams
- And then another – plus 10% from the weight already received.
EXAMPLE: girl weighing 52 kg with an increase of 73 cm
45 kg (152.2 cm) + 7.2 kg (note – 900 g per 2.,. 54 cm above 152.2 cm and up to 173 cm) = 52.2 kg.
52.2 kg + 5.2 kg (10% of the resulting weight) = 57.4 kg.
That is, the weight norm in this case is 57.4 kg.
Calculate the ideal weight can be according to the Brock formula
Also very interesting way, taking into account several factors at once.
First of all, you should determine the type of your physique . For this we are looking for the thinnest place on the wrist and clearly measure its circumference.
And now compare with the table:
- asthenic type: for women – less than 15 cm, for the stronger sex – less than 18 cm
- normostenicheskaya type: for ladies – 15. -17 cm, for the stronger sex – 18-20 cm
- And hypersthenic type:. for women – more than 17 cm, for the stronger sex – more than 20 cm
What’s next.?
And further we consider according to the formula:
- Growth (in cm) – 110 (if you are less than 40 years old).
- Growth (in cm) – 100 (if you are over 40 years old).
- Subtract the resulting number of 10% if you are an asthenic.
- Add to the number obtained 10% , if you are hypersthenic. Calculation of the weight norm by John McCallum’s method
The formula created by the expert methodologist, and considered one of the best.
The method based on measuring the circumference of the wrist is based.
Namely:
- Circumference of wrist (in cm) x 6.5 = chest circumference.
- 85% of the circumference of the chest = circumference of the thighs.
- 70% of the circumference of the chest = waist circumference.
- 53% of the circumference of the chest = circumference of the thigh.
- 37% of the circumference of the chest = neck circumference.
- 36% of the circumference of the chest = circumference of the biceps.
- 34% of the circumference of the chest = shin circumference.
- 29% of the circumference of the chest = circumference of the forearm.
Of course, the resulting figures are averaged, that is – average.
Why the weight does not go away with diet and exercise – major weight loss errors
applying calculations, it is important to understand what your ideal weight – the one in which you are most comfortable live, breathe and work.
The main thing is health!
