Once we say to ourselves: “That's it, I’ll run in the mornings, monitor nutrition and weight, drink only healthy fluid and establish my sleep.” But then difficulties arise that interfere with all this. The good news is that there are many smart gadgets that you can provide health care for.

1. FatSecret

Completely free application with an intuitive interface. It takes into account the total calorie content, the amount of consumed proteins, fats and carbohydrates. A large database of products in which you can find dishes of popular restaurant chains. In addition to BJU (proteins, fats, carbohydrates), the program takes into account the amount of sugar, fiber, sodium, cholesterol. Shows statistics for the day, current and last week.

In the application, you can also take into account calorie consumption, choosing from several types of activity. But you should understand that the program will offer approximate values. It is almost impossible to track the exact energy consumption without a heart rate monitor.

What smart scales are called diagnostic?


In addition to the basic task of measuring mass, some scales (they are also called diagnostic) are able to assess body composition with the help of electrical resistance in tissues - bioimpedansometry.

1. Bioimpedance analysis Is a body composition diagnostic method that determines the percentage of fat, muscle, fluid, and bone mass. It is based on a weak electrical impulse, which is sent by the device through soft tissues.

2. For diagnostic scales The sensors are placed directly on the platform, where they become feet, so you do not need to attach the electrodes throughout the body, as in medical stationary devices.

3. It is important to know: The readings of the scales depend on the amount of fluid in the body, so it is ideal to weigh in the morning on an empty stomach. During the day, your weight can increase up to 2 kg due to meals and drinks. Weigh up to physical exertion. We get up on the scales with dry feet. We take measurements regularly so that the dynamics of changes are visible.

What is determined and how?

Depending on the model, type and manufacturer, smart scales calculate a number of important health metrics, which we will discuss below. Such devices are equipped with analyzers of body weight and fat.

Any scale works with weight, not just smart. However, in the case of smart devices, measurement statistics can be viewed in the application on the phone.

Why know your weight? During a diet and exercise, a weight change schedule helps you quickly and easily evaluate the effectiveness of your lifestyle. Moreover, proof of past successes with the loss of extra pounds motivates to continue the whole venture.

How is it measured? The load sensors are responsible for measuring the weight, which are deformed under the user's weight and supply an electrical signal to the processor. The processor converts it to the number you see on the screen.

Body Mass Index (BMI)

Body mass index (BMI) is a value that shows how much a person’s weight corresponds to his height. The World Health Organization interprets the index as follows:

  • 16 and less - pronounced deficiency of body weight
  • 16-18.5 - insufficient body weight
  • 18.5-24.99 - normal
  • 25-30 - obesity
  • 30 and more - obesity

Why know BMI? The index helps you understand what stage you are in to make conclusions.

How is it measured? The smart weights application asks the user to enter their height during registration. And then, BMI = body weight in kilograms divided by the square of growth.

Example. If your weight is 75 kg with an increase of 1.69 m, then BMI = 65: 1.69: 1.69 = 26.2 (you have a state of obesity).

Body fat percentage

Fat - like they are extra pounds! We know how much fat, we set the goal of losing weight. However, not all fat is superfluous. Scales work with a percentage of subcutaneous fat, which accounts for about 80% of all body fat.

Why know% fat? This indicator for athletes is even more important than what the arrow shows weights. If you have an understanding of how much subcutaneous fat is in you, then subtracting it from body weight and we get muscle mass. For example, if after two months of diet or training you lost 6 kg, it is important that at least 5-5.5 kg of them are fat. Here we will prompt the scales.

How is it measured? Diagnostic scales determine the percentage of body fat by tissue resistance: fat resistance is higher.

Visceral fat

Visceral fat, unlike subcutaneous fat, envelops internal organs and forms a characteristic “beer belly”.

Why know% visceral fat? Visceral fat is associated with the manifestation of dementia, Alzheimer's disease, it blocks the flow of blood to the internal organs, which causes shortness of breath and fatigue. Health damage is caused not so much by subcutaneous as by visceral fat. It is important to reduce its share in the body.

How is it measured? As in the previous paragraph, through the resistance of tissues and subsequent calculation according to medical metrics.

Muscle percentage

The volume of muscle tissue is interesting for athletes and everyone who wants to feel good and live long.

Why know% muscle tissue? With the same weight and height, two people outwardly can look diametrically opposite. One will have an athletic figure and the other will look like a pillow.

How is it measured? Each manufacturer of smart scales has its own formulas that they do not disclose. The base is the difference between body weight and body fat.

Skeletal muscle percentage

Skeletal muscles are so called because they are attached to the skeleton and together with it form the musculoskeletal system. On average, their weight is about 40% of the total body weight of a person, a trained athlete will have a higher percentage.

Why know about these muscles? Musculoskeletal mass is one of the indicators of human health, it can be used to judge endurance and physical development.

How is it measured? Diagnostic scales calculate the percentage of skeletal muscles according to their own algorithms, based on bioimpedance measurement data.

Bone mass percentage

This is not the same as the weight of the entire skeleton. The bone tissue of an adult living person consists of 60–70% of mineral components and 30–40% of organic matter. The skeleton of an adult weighs from 7 to 10 kilograms. Mineral bone mass averages 2 - 3 kg in women and 2.6 - 3.6 kg in men.

Why know about your bone mass? Bones slowly degrade with age. For adults (and women in particular), this is fraught with osteoporosis: a disease in which more bone tissue is destroyed than created. Fortunately, preventing the problem is easy - it’s enough to lead an active lifestyle, and this will affect the increase or preservation of bone mass: strong muscles correlate with the thickness and strength of the bones.

How is it measured? According to formulas and known statistics of age groups.

Water percentage

The human body contains 50–75% of water, the balance of which in the body is mobile. A person sweats, drinks, breathes, takes food, visits the toilet, which leads to a change in the volume of fluid in the body.

Why count water? This is useful for dieters and fitness fanatics. The former take the water balance offset for real loss of excess weight. The second, on the contrary, collect water and cannot calculate how much muscle mass they added. The presence of a real figure allows you to evaluate reality and adjust the approach.

How is it measured? Since water in the body conducts electricity, the bioimpedance method reveals its volume well.

Basic metabolic rate (basal metabolism)

Basal metabolism is the minimum number of calories to maintain the body at rest.

Why do I need this? The higher the metabolic rate, the faster calories and, consequently, fat are burned. Increasing muscle mass, playing sports, active life can significantly accelerate this process.

How is it measured? Using a standard equation based on height, weight, age and gender adjusted for the percentage of muscle mass.

How smart scales work

Smart scales measure a lot of interesting indicators. And how does all this data get into the system where it is stored and processed?

Like many other modern gadgets, smart scales work in tandem with mobile devices: smartphones, tablets. Some have online interfaces and PC applications, but mobile apps are still more common.

Data is stored in the cloud of the manufacturer of the scales, and the entire array is processed there. To send them there, the device connects to the Internet. There are two ways to do this: synchronize the scale with a mobile gadget, or connect directly to your home wireless network. In the first case, the Bluetooth standard is used, in the second - Wi-Fi.

When connecting via Bluetooth, the smartphone will have to be reached before each weighing. This can be considered an inconvenience, but a moot point. When the user sees all the data every time, he will not be able to ignore or not notice the changes in his body. For diet and weight maintenance, mindfulness is an absolute advantage.

2. For diagnostic scales The sensors are placed directly on the platform, where they become feet, so you do not need to attach the electrodes throughout the body, as in medical stationary devices.

3. It is important to know: The readings of the scales depend on the amount of fluid in the body, so it is ideal to weigh in the morning on an empty stomach. During the day, your weight can increase up to 2 kg due to meals and drinks. Weigh up to physical exertion. We get up on the scales with dry feet. We take measurements regularly so that the dynamics of changes are visible.

What is determined and how?

Depending on the model, type and manufacturer, smart scales calculate a number of important health metrics, which we will discuss below. Such devices are equipped with analyzers of body weight and fat.

Any scale works with weight, not just smart. However, in the case of smart devices, measurement statistics can be viewed in the application on the phone.

Why know your weight? During a diet and exercise, a weight change schedule helps you quickly and easily evaluate the effectiveness of your lifestyle. Moreover, proof of past successes with the loss of extra pounds motivates to continue the whole venture.

How is it measured? The load sensors are responsible for measuring the weight, which are deformed under the user's weight and supply an electrical signal to the processor. The processor converts it to the number you see on the screen.

Body Mass Index (BMI)

Body mass index (BMI) is a value that shows how much a person’s weight corresponds to his height. The World Health Organization interprets the index as follows:

  • 16 and less - pronounced deficiency of body weight
  • 16-18.5 - insufficient body weight
  • 18.5-24.99 - normal
  • 25-30 - obesity
  • 30 and more - obesity

Why know BMI? The index helps you understand what stage you are in to make conclusions.

How is it measured? The smart weights application asks the user to enter their height during registration. And then, BMI = body weight in kilograms divided by the square of growth.

Example. If your weight is 75 kg with an increase of 1.69 m, then BMI = 65: 1.69: 1.69 = 26.2 (you have a state of obesity).

Body fat percentage

Fat - like they are extra pounds! We know how much fat, we set the goal of losing weight. However, not all fat is superfluous. Scales work with a percentage of subcutaneous fat, which accounts for about 80% of all body fat.

Why know% fat? This indicator for athletes is even more important than what the arrow shows weights. If you have an understanding of how much subcutaneous fat is in you, then subtracting it from body weight and we get muscle mass. For example, if after two months of diet or training you lost 6 kg, it is important that at least 5-5.5 kg of them are fat. Here we will prompt the scales.

How is it measured? Diagnostic scales determine the percentage of body fat by tissue resistance: fat resistance is higher.

Visceral fat

Visceral fat, unlike subcutaneous fat, envelops internal organs and forms a characteristic “beer belly”.

Why know% visceral fat? Visceral fat is associated with the manifestation of dementia, Alzheimer's disease, it blocks the flow of blood to the internal organs, which causes shortness of breath and fatigue. Health damage is caused not so much by subcutaneous as by visceral fat. It is important to reduce its share in the body.

How is it measured? As in the previous paragraph, through the resistance of tissues and subsequent calculation according to medical metrics.

Muscle percentage

The volume of muscle tissue is interesting for athletes and everyone who wants to feel good and live long.

Why know% muscle tissue? With the same weight and height, two people outwardly can look diametrically opposite. One will have an athletic figure and the other will look like a pillow.

How is it measured? Each manufacturer of smart scales has its own formulas that they do not disclose. The base is the difference between body weight and body fat.

Skeletal muscle percentage

Skeletal muscles are so called because they are attached to the skeleton and together with it form the musculoskeletal system. On average, their weight is about 40% of the total body weight of a person, a trained athlete will have a higher percentage.

Why know about these muscles? Musculoskeletal mass is one of the indicators of human health, it can be used to judge endurance and physical development.

How is it measured? Diagnostic scales calculate the percentage of skeletal muscles according to their own algorithms, based on bioimpedance measurement data.

Bone mass percentage

This is not the same as the weight of the entire skeleton. The bone tissue of an adult living person consists of 60–70% of mineral components and 30–40% of organic matter. The skeleton of an adult weighs from 7 to 10 kilograms. Mineral bone mass averages 2 - 3 kg in women and 2.6 - 3.6 kg in men.

Why know about your bone mass? Bones slowly degrade with age. For adults (and women in particular), this is fraught with osteoporosis: a disease in which more bone tissue is destroyed than created. Fortunately, preventing the problem is easy - it’s enough to lead an active lifestyle, and this will affect the increase or preservation of bone mass: strong muscles correlate with the thickness and strength of the bones.

How is it measured? According to formulas and known statistics of age groups.

Water percentage

The human body contains 50–75% of water, the balance of which in the body is mobile. A person sweats, drinks, breathes, takes food, visits the toilet, which leads to a change in the volume of fluid in the body.

Why count water? This is useful for dieters and fitness fanatics. The former take the water balance offset for real loss of excess weight. The second, on the contrary, collect water and cannot calculate how much muscle mass they added. The presence of a real figure allows you to evaluate reality and adjust the approach.

How is it measured? Since water in the body conducts electricity, the bioimpedance method reveals its volume well.

Basic metabolic rate (basal metabolism)

Basal metabolism is the minimum number of calories to maintain the body at rest.

Why do I need this? The higher the metabolic rate, the faster calories and, consequently, fat are burned. Increasing muscle mass, playing sports, active life can significantly accelerate this process.

How is it measured? Using a standard equation based on height, weight, age and gender adjusted for the percentage of muscle mass.

How smart scales work

Smart scales measure a lot of interesting indicators. And how does all this data get into the system where it is stored and processed?

Like many other modern gadgets, smart scales work in tandem with mobile devices: smartphones, tablets. Some have online interfaces and PC applications, but mobile apps are still more common.

Data is stored in the cloud of the manufacturer of the scales, and the entire array is processed there. To send them there, the device connects to the Internet. There are two ways to do this: synchronize the scale with a mobile gadget, or connect directly to your home wireless network. In the first case, the Bluetooth standard is used, in the second - Wi-Fi.

When connecting via Bluetooth, the smartphone will have to be reached before each weighing. This can be considered an inconvenience, but a moot point. When the user sees all the data every time, he will not be able to ignore or not notice the changes in his body. For diet and weight maintenance, mindfulness is an absolute advantage.

Scales with a Wi-Fi module connect to a wireless network and upload data to the Internet on their own. It is more convenient and faster than connecting via Bluetooth. The method, however, has a specific drawback. Many smart scale models recognize the person who stood on them by weight and other characteristics. But when two people with approximately the same weight live in the house, the system may incorrectly recognize them. Situations of this type are processed separately, but this does not mean that the data does not have to be corrected subsequently.

Diagnostic scales are usually not recommended for pregnant women, and such devices are categorically contraindicated in people with implanted pacemakers. Some developers took this factor into account and added modes of simple weighing, without diagnosis, and pregnancy management. The latter records the days, shows the expected date of birth of the child and calculates the weight gain. This is a fairly rare feature.

The level of software for smart scales varies - and it's not just about pregnancy. Here you need to pay attention to three areas: the depth of analysis, the presentation of data and the ability to share them with other applications. The topic was partially discussed at the beginning of the article, but we will consider it in more detail.

As a rule, the more data is collected, the more detailed the analysis. Smart scales without bio-impedance sensors show weight and BMI trends. Diagnostic scales show graphs of fat, muscle, water - depending on what they can measure.

Which model to choose?

Your personal choice of weights should be dictated by three factors: price, goals for which they are needed, and the presence of other fitness devices.

Since technology is constantly improving and democratizing, more expensive smart scales will not necessarily be a cut above the rest of the models. This is especially true for diagnostic scales. Bioimpedansometry is a well-studied and fairly old technology. Any comparisons will most likely not be objective.

The functionality of smart scales must meet the needs. It makes no sense to purchase or give a device, half of which a person will not use. For a simple and regular weight tracking, a simple model is suitable.

What smart scales are called diagnostic?


In addition to the basic task of measuring mass, some scales (they are also called diagnostic) are able to assess body composition with the help of electrical resistance in tissues - bioimpedansometry.

1. Bioimpedance analysis Is a body composition diagnostic method that determines the percentage of fat, muscle, fluid, and bone mass. It is based on a weak electrical impulse, which is sent by the device through soft tissues.

2. For diagnostic scales The sensors are placed directly on the platform, where they become feet, so you do not need to attach the electrodes throughout the body, as in medical stationary devices.

3. It is important to know: The readings of the scales depend on the amount of fluid in the body, so it is ideal to weigh in the morning on an empty stomach. During the day, your weight can increase up to 2 kg due to meals and drinks. Weigh up to physical exertion. We get up on the scales with dry feet. We take measurements regularly so that the dynamics of changes are visible.

What is determined and how?

Depending on the model, type and manufacturer, smart scales calculate a number of important health metrics, which we will discuss below. Such devices are equipped with analyzers of body weight and fat.

Any scale works with weight, not just smart. However, in the case of smart devices, measurement statistics can be viewed in the application on the phone.

Why know your weight? During a diet and exercise, a weight change schedule helps you quickly and easily evaluate the effectiveness of your lifestyle. Moreover, proof of past successes with the loss of extra pounds motivates to continue the whole venture.

How is it measured? The load sensors are responsible for measuring the weight, which are deformed under the user's weight and supply an electrical signal to the processor. The processor converts it to the number you see on the screen.

Body Mass Index (BMI)

Body mass index (BMI) is a value that shows how much a person’s weight corresponds to his height. The World Health Organization interprets the index as follows:

  • 16 and less - pronounced deficiency of body weight
  • 16-18.5 - insufficient body weight
  • 18.5-24.99 - normal
  • 25-30 - obesity
  • 30 and more - obesity

Why know BMI? The index helps you understand what stage you are in to make conclusions.

How is it measured? The smart weights application asks the user to enter their height during registration. And then, BMI = body weight in kilograms divided by the square of growth.

Example. If your weight is 75 kg with an increase of 1.69 m, then BMI = 65: 1.69: 1.69 = 26.2 (you have a state of obesity).

Body fat percentage

Fat - like they are extra pounds! We know how much fat, we set the goal of losing weight. However, not all fat is superfluous. Scales work with a percentage of subcutaneous fat, which accounts for about 80% of all body fat.

Why know% fat? This indicator for athletes is even more important than what the arrow shows weights. If you have an understanding of how much subcutaneous fat is in you, then subtracting it from body weight and we get muscle mass. For example, if after two months of diet or training you lost 6 kg, it is important that at least 5-5.5 kg of them are fat. Here we will prompt the scales.

1. Fitness bracelets

According to the analytic company Gartner, the number of wearable smart watches is 53 million, which is 30% of the total sales of wearable technology. The set of functions includes the main ones, which read the pulse and keep track of the steps taken during the day, and additional ones: sending messages, calling, viewing social media feeds, notifications.

Fitness bracelets make sure that you do not stay too long, and remind you if you need to interrupt for relaxation and a little exercise. They monitor the rhythm of the heart, help the user to adhere to the daily routine. Such a device will be an assistant in any activity: from office work to classes in the hall.

Fitness bracelets are produced by Xiaomi, Honor, Samsung and Apple, the average price is 2000-4000 rubles, for it you will receive compatibility with the Android, iOS platforms, heart rate monitor, sleep monitoring, calories, physical activity, SMS, call notifications. The most expensive ones cost from 20 to 32 thousand rubles, they can answer calls, use contactless payment, the screen is also improved and the level of moisture protection is higher. The photo shows fitness bracelets from Xiaomi (left) and Apple (right).

2. Smart scales

These are the same scales that measure a person’s body weight, but they calculate the body mass index, percentage of fat, muscle mass, water, protein, bones for the user. They also evaluate the basal metabolic rate (UBM), which indicates whether the body works effectively for your age. You set the goal you want to achieve and track the changes on schedule. Scales transmit information to phones, tablets and other devices via Bluetooth or Wi-Fi network. Each device has a corresponding application that keeps a record of your data. You can also add other family members or friends. Smart scales can be bought on average for 2000-3000 rubles.

3. Heart rate monitors

The main difference between a heart rate monitor and a fitness bracelet is that it consists of two elements, one of which is attached with a belt to the chest, and the second on the wrist in the form of a receiver. For better contact, the sensor is lubricated with water or a special gel. The heart rate monitor records and monitors the heart rate. It beeps if the pulse goes beyond the comfort zone to reduce the tempo, and vice versa.

Most often, heart rate monitors are used in cyclic sports: running, swimming, cycling. The device is suitable for professional athletes, amateurs and those who especially monitor the work of the heart. The price range of heart rate monitors ranges from 50 to 80 dollars.

4. Smart bottle of water

To maintain the water balance at the right level, you need to drink a certain amount of water per day, which for each person is calculated separately depending on body weight, the goal they want to achieve, and other indicators. The smart bottle is equipped with a sensor that keeps track of the drunk, reminds you if you have not drunk water for a long time. In conjunction with other devices, a smart bottle will show the history of water consumption, as well as adjust the necessary rate depending on the level of activity.

Smart bottles of Icewater and Ozmo.

5. Vitaminometer

This is a device that measures the amount of vitamins and minerals in the body. It is a pencil with a metal case and an application where indicators are displayed. The device’s operation is based on the bioelectric resistance of tissues - you touch a certain part of the body with a stylus, hold the pencil body with your fingers, and a closed circuit appears through the body. The vitometer compares the obtained values ​​with the optimal ones and gives recommendations in the application itself.

Anton Gerasimov, an implant surgeon, candidate of medical sciences, considers this device to be unscientific and does not recommend relying on it.

“When I first heard about the vitamin meter, I was expecting a device with which the patient can scarify at home and use a drop of blood to determine the level of vitamins and minerals in the body. Even in this case, there would be no guarantee that the data is accurate, but then there would be at least some kind of science. But in fact, we have a gadget that "determines" the content of vitamins in humans by the electrical resistance of the skin. But there is simply no evidence that electrical resistance at different points in the body unambiguously indicates a certain level of vitamins. So today the vitaminometer is unscientific. And to find out how to eat properly in accordance with your views on life, the characteristics of the body and financial capabilities, the most optimal is to seek the advice of a nutritionist. It will be much more useful. "

6. The device for posture

The main objective of this device is to help a person develop the habit of holding a posture. The device can be of different types and forms, attached directly to the body or to clothes. The sensor remembers the correct, even position of the back and vibrates or gives a signal to the application when you are hunched, bent or deviated. It is designed for people who spend a lot of time in one position, for example, office workers, students. The disadvantage of this device is that the user himself initially sets the correct back position. The device does not cure, does not correct back problems, but helps to develop a healthy habit. Such devices cost from 55 to 150 dollars.

7. Applications with training plans

Not everyone can afford to hire a personal trainer so that sports activities are productive and productive. Some applications will make up a complete individual program for classes. You set the desired goal: pumping and toning muscles, weight loss, development of flexibility - the application itself will calculate the correct load and tell you the sets of exercises.

According to Yaroslava Naumenko, a personal trainer (ISSA), the founder of an online fitness school, the disadvantages of this application are as follows:

“Physical unpreparedness for exercises, limitation of mobility, simplification of equipment, lack of motivation and lack of“ standing of the trainer above the soul ”... People will train loose, not skillfully and ineffectively, therefore most often they leave the applications for trainers. Ideally, you should already have a good, delivered equipment, and then train at least for the application, at least for any other programs. The advantages include low price and independence (at least on a business trip, at least in any gym - you are with a training plan and an image of what needs to be done). “

Nikita Skripnik, physiologist and personal trainer, author of @skripniknik blog, also notes:

“There are pitfalls in such training. Improper exercise can lead to chronic pain or aggravate existing ones. An experienced trainer takes into account at least a few dozen factors in each training session. Training applications do not have this functionality. “
