Why buy analyzer scales and what indicators to pay attention to

Scales analyzer - show how well you feel, why measure several important indicators of the body. We will talk about how and why this is done today.

All metrics of smart analyzer scales somehow record what helps you lose weight or gain weight (depending on the goals). Even when it comes to hydration, we must understand that this parameter is not just introduced. At the same time, having a certain degree of conditionality, they still help to track trends in time , and with some, even superficial, studying the issue, these trends will help to draw some conclusions.


The technology is based on bioimpedance analysis, known since the 60s, based on measuring the electrical resistance of tissues. This analysis is considered accurate and helps to identify a number of diseases and to assess the composition of the human body for compliance with accepted standards.

Smart scales are a kind of “truncated” bio-impedance analyzer, since, as you understand, there are much fewer leads, only in the heel area, but this may be enough to calculate the main parameters.

Main indicators of bioimpedancemetry

Also in the process of bioimpedance analysis, the active cell mass, basal metabolic rate and some other parameters can be calculated.

With the help of analyzer weights, everything starts with weight, a parameter that does not require special explanation, and body mass index.

Where is biomedical analysis applied

Clinical biomedical analysis, more detailed, also allows you to assess the risk of various diseases of the musculoskeletal system, urinary system, diabetes (more often - type II), as well as diseases associated with a lack of protein in the body.

Also with the help of this study can assess the viability of tissue during transplantation, etc.


It is not recommended to perform bioimpedance in pregnancy or the presence of a pacemaker, as well as during menstruation, fever or if the skin is damaged at the points of contact with the electrodes.

Smart scales as a bio-impedance analyzer today have ample opportunities. We will list the most important, central parameters by which the assessment is made:


Body mass index is more like math than analysis. The simplest parameter, which is calculated by the formula: weight in kg / height in m ^ 2 .

That is, for example, 65 / (1.70 * 1.70) = 22.4.

Fat level

As already noted, any analyzer scales are approximate figures in all data except for weight, but these figures help to track trends : if the percentage of fat increases from measurement to measurement, then this is a bad signal, and count on the fact that “all is false " it does not follow.

You can also calculate the percentage of fat yourself: for this you need to divide the fat mass by body weight, but for this you need to know the first parameter, which with accuracy will give only hydrostatic weighing. Analyzer scales, on the other hand, produce a calculation “in mind” - passing a current through one leg and receiving a signal with output losses - on the other leg - they divide the figure and give you an initial percentage, which can then decrease / increase depending on habits and image of life.

For men, as can be seen, it is considered to be the range from 6 to 13 percent - close to the athletic rate, more than 25% - obesity.

Norms M and F

Problems with determining the level of fat in the body would not be so acute if the excess of such would not be a possible factor in other, very sad diseases of the cardiovascular system, diabetes, etc., therefore even in this approximate form this percentage is very important and demanded metric!

Bone mass

The most important parameter, which among others is analyzing smart scales! Bone mass, or the mass of the mineral composition of the skeleton is shown in kg and must meet the following standards:

Decline is a bad sign, because, even guided by his own logic, a person must understand that the strength of bones = support and support to muscles and internal organs. If there is a loss in this trend, it is necessary to consult a doctor and make the proposed tests, since among other things, losses in bone mass may indicate osteoporosis , a disease that is now on a par with oncology, diabetes and cardiovascular diseases.

Excerpt from statistics in the US
Every year, 1.5 million fractures associated with osteoporosis are recorded, of which 700 thousand are spinal fractures, 250 thousand are hip fractures, 250 thousand are distal radial bone fractures and 300 thousand are fractures in other parts of the skeleton. The risk of fractures of the spine, femoral neck and distal radius is 40% for white women and 15% for white men aged 50 years and older. Up to 50% of patients with a fracture of the femoral neck cannot do without help, and 15 to 20% of patients die within 1 year. The number of osteoporotic fractures in the world is increasing from 1.7 million in 1990 to an increase to 6.3 million in 2050

From here

Also, more in-depth studies of bone tissue can reveal certain types of cancer in children.

In any case, this data should not be underestimated.

Muscle Mass Analysis

An increase in muscle mass is conventionally equated to a decrease in fat mass: more muscles - less fat, which is the main criterion for weight loss. However, this is not always the case.

In some sense, the danger is low-calorie diets, which some people use “paired” with physical exertion: there is little protein in such diets, so losing weight - a person loses weight, but not due to burning fat, but due to the loss of muscle mass!

In this connection, if the indicator of muscle mass, following the weight decreases, then the trend can also be considered unfavorable, therefore it is customary to monitor this with the help of improvised tools, including weights.

You can calculate muscle mass yourself:

Here is one of the tips
In order to determine the percentage of the weight of the muscles in the human body auxiliary devices are needed. These are the caliper and tailor centimeter.

If the caliper is missing, it can be easily replaced with a caliper. Before you begin to determine the muscle mass in the human body, you need to be aware of what body measurements you need to take to get started and take into account all sorts of nuances of this process.

To start the calculation is to measure with a centimeter, which will need to measure four circles:

  • Shoulder
  • Forearm
  • Shin
  • Hip

It is recommended to measure the shoulder only in a calm state, so you should not strain the muscles in the measurement process. Try to measure the shoulder in the place where most of the muscles are located.

When taking measurements from the forearm, care must be taken to ensure that the hand is not in tension and freely hung.

To measure the shin, it is necessary to take measurements of the calf, preferably in the place where they are found most.

When measuring the hips, it is necessary to become even, so that the weight of the body is evenly distributed over the two legs. After that, you should measure the centimeter, covering the thigh under the gluteal fold.

After the required indicators have been removed, for further calculations you will need to know more and subcutaneous fat folds. The caliper will help to do this. Based on the data obtained, it is possible to calculate how much muscle mass a person has.

In order to calculate the muscle mass of men, you can use the Mateka formula. The following formula has been developed for this: M = L * r2 * K

In order to understand the calculations, you can use the following decoding:

  • M - this is muscle mass, which we need to calculate.
  • L - an indicator that characterizes the growth of men. For this formula, the growth is recommended to take in centimeters.
  • r - to calculate this indicator, you must perform three steps. The first step is to calculate the sum of the four indicators obtained at the very beginning of the determination of mass - this is the coverage of the shoulder, forearm, lower leg and thigh. The resulting amount must be divided into 25, 12. The second action is similar to the first, because it also needs to know the sum of the indicators and divide it by 100. In the second step, measurements of the subcutaneous fat folds are taken to calculate. The essence of the third action is to obtain the difference between the first action and the second. This difference is an indicator of r, which you will need to substitute in the formula that was given above.
  • K is a constant figure, which is 6.5.

According to this formula, provided that the calculations were carried out, right, you can determine the weight of the muscles in the human body.

The rate of lean body mass in percent for men and women is different. So, for a woman, the rate is 35% of the entire body mass. But the rate for men is slightly higher and is about 43%.
Of course, with regular physical exertion and proper nutrition in an athlete's body, the processes of increasing muscle mass are activated more than in a person who has no relation to sports. Therefore, the norm for an athlete is 50% of the muscles of the total body mass.

From here

It is necessary to take into account the fact that the scales are non-segmented muscle mass, including both smooth and skeletal muscles, in other words, an average indicator, however, with a uniform decrease in weight and muscle mass, it is necessary to guess that something probably went wrong. review diet and workouts!

Body fluid level

Primarily in the scales, this metric is introduced because a decrease in the level of fluid leads to a set of fat, in other words, for those who lose weight, it is important to keep track of this as well. Normal is the level of liquid 50-75%.

You also need to understand that water in general has one of the key roles in our health. Here are some of the “spheres of influence”:

By reducing this indicator, it is necessary to consult with a specialist, as a lack of water worsens the work of the kidneys, increases the load on the liver, etc., which can lead to serious chronic diseases.

What scales to choose

Weights analyzers are extremely numerous, and each model claims to be accurate. Attention deserves the novelty that we brought recently - smart scales MGB Body fat scale .

First, they offer the widest range of metrics that will give odds to most popular models, including Xiaomi. Secondly, the price - it is more than viable in this category and, finally, dimensions, which is important. But first things first.


Scales are synced via Bluetooth with IOS and Android devices , after which you need to register.

At the moment we are busy translating the application, but so far the software is in English. However, everything is pretty clear. In total, the analysis is performed on 13 metrics, among which both those that we have already described and others:

The data is instantly uploaded to the main screen: the key parameters are the weight, the body mass index, the fat mass, and then the list contains additional information.

For each metric, you can get a decryption, however, while in English.

The application supports "multi-user" mode.


Scales have, one can say, a classic look: a white square with a display in the middle in the upper part. Along the edges are leads to which you need to get up when weighing, barefoot.

A distinctive feature of this model is its small size: the square 26X26 is only 2.5 cm from the floor.

It will, incidentally, be on stable rubberized legs, that is, they will not go anywhere on the tile.

Scales from 4 "mizinchikovy" batteries work:

The device is sold in a thin, non-bulky box, from the back side of which you can find links to both applications, as well as transferring the received data:

Device price

Now, in terms of price / quality / consumer accuracy, they look very good: at retail this model costs 2490 rubles , which seems to be beneficial with such a set of characteristics.
