The media is now crammed with ads, which the actors are pretty thin women. Figure of the “barbie doll” for many women is the standard of beauty. However, physicians have become increasingly draw public attention to the fact that the figure models are by no means the standard of beauty, and so, moreover, is not the average for health. Since thinness is no less dangerous to health than obesity. The best possible weight should be somewhere between these two extremes.
Popular simple formula used to determine the optimal weight for their height (height in centimeters minus 100) is not accurate. The most appropriate measure, which assesses body fat is body mass index (bmi), in the English version – body mass index (bmi). It is calculated by the formula:
Body weight (in kg.) / square of height (in meters)
Example: a woman has a height 1.77 m and a weight of 68kg. Bmi = 68/1, 77h1, 77 = 21 (21.8)
Now try to determine your bmi. If the result is between 18.5 and 24.9 – the size of your figure is correct, you are in a safe weight class. Bmi greater than 30 indicate obesity. It is hazardous to health, and you need to go on a diet and if more than 40, then go to an endocrinologist.18.5 indicates a lack of weight gain and painful thinness. In this case, too, need to see a doctor.
A bmi of 25 to 29.9 speaks about overweight. In this case, you do not need a diet, and should be fed a balanced, move more, exercise and sport (article about a balanced diet, diets, physical activities can be found in the archive of our newsletter). Reduce weight in this case, you need if you already have health problems, or you are exposed to risk factors – diabetes, high blood cholesterol, high blood pressure if the waist perimeter is bolee101sm. Large waist size indicates that the excess fat is stored around the abdomen, rather than in the hips , which is more dangerous to health.
To more accurately determine the optimal bmi by weight for physically, you must consider its own formation. This can be done by the circumference of your wrist. For example, if your wrist circumference is 13-14cm, the optimal values of bmi for you will 18,5-20, with the wrist in a 14.5-16.5 cm, the optimal bmi will be in the range 21-23, and at the wrist in 17 -18cm they are 24-25.
It should however be borne in mind that bmi is not suitable for every person. It is not suitable for pregnant women and persons under 18 years of age. Since bmi suggests that obesity is associated with the accumulation of excess fat in the body, and does not consider lean body mass (muscle tissue and has a larger weight than the oil), then it should not be guided athletic individuals for which overweight is not due to fat accumulation and is not associated with health risks.
