How much can and should you weigh? Is there a difference between these numbers and how do I get them? And most importantly - what to do if you weigh within normal limits, but still feel fat? We deal with it together with a nutritionist.

Ask any nutritionist and he will tell you that the first step in losing unwanted weight is to set a goal. What do you want to achieve? Weak figure or wellness? When making this decision for yourself, measure your current performance: weight, height and volume. By the way, it is correct to measure the waist in the middle between the lower border of the ribs and the protruding bone in front of the hip joint, and not at all in the narrowest part of the abdomen. It is quite possible that the numbers obtained coincide with your goal and you will not have to lose weight. And if you have to, then you need to find out exactly how many pounds. For this purpose, it is worth calculating the body mass index (the ratio of height to weight). BMI can indicate both overweight and underweight. A normal number is considered to be in the range from 18.5 to 24.9  .

So to calculate your BMI, divide your weight by the height squared. For example, with a height of 165 cm and a weight of 60 kg, BMI is calculated by the formula: 60: (1.65 x 1.65) and will be 22. Or use online calculators that will calculate everything for you.

In addition to BMI, there is another important indicator - the percentage of body fat. Helps to determine health. Athletes use this method more often.

HOW TO CALCULATE THE PERCENTAGE OF BODY FAT?

Here a simple formula and calculator will not work. Of course, the percentage of fat can be determined by eye, by feeling your sides. Or by listening carefully to yourself: do you consider yourself fat with a seemingly normal BMI? There are also calipers - these are special devices that are sold in pharmacies. But the veracity of their testimony raises many questions. As well as home electronic scales (the error can reach 20%, and this, you know, is a lot).

When you step on the scales barefoot, a small amount of electricity flows through your body. The scale measures the rate at which it returns because muscle tissue and adipose tissue conduct current differently. Based on these data, a conclusion is drawn.

A more accurate way is to measure bioimpedance. This is a test that can be done in a lab or fitness center. Its error is only 5%.

WHY MEASURE VOLUMES?

Even if your body mass index is normal, your own reflection in the mirror may not be encouraging. Waist and thigh measurements will help you determine what is wrong. For example, in women, the waist should not be more than 80 cm in circumference. In men - more than 94 cm. Otherwise we can talk about the accumulation of fat in the abdominal area, ie in the abdominal wall around the internal organs. This not only looks unsightly, but also carries certain health risks. For example, the appearance of cardiovascular disease. Measurements should be taken every 6 or 12 months and you should start adjusting your diet and actively working on yourself if the numbers are close to the allowable limit.

With the hips, things are a little more complicated. Proportion is important here. Divide the waist at your hips. For women the maximum allowable value is 0.85, for men - 0.9.

Only the three indicators together can tell if you need to lose weight. If at least one of them is overestimated, then it is necessary to take at least this issue under control. And if all is well, then try to shift the focus from the numbers on the scales to the quality of your body. Maybe you just need to increase your muscle mass a bit.
