Analysis of body composition

Analysis of body composition is an important element in the process of weight loss. Performed systematically, e.g. every month, during a slimming diet, it shows how parameters such as: fat content, muscle mass, bone mass, hydration of the body, metabolic age, basic metabolism and many others change. The most helpful parameter to determine the effectiveness of the diet is the measurement of body fat.

Why is the body composition analysis performed?

Body composition analysis is performed for a variety of reasons, including:

  1. Health monitoring: Helps to determine if the body is at a healthy weight and if there are any health problems such as obesity or underweight.
  2. Evaluate the effectiveness of exercise and nutrition programs: Can help determine whether a particular exercise or nutrition program is working for a person.
  3. Nutrition and Workout Planning: Helps you determine your ideal body weight, physical activity level and calorie requirement, which helps you develop a nutrition and workout plan.
  4. Research: Body composition analysis is also used in research to understand how different factors affect body composition.

There are different methods of body composition analysis, such as weight measurement, waist circumference measurement, skin fold thickness measurement and DXA (dual X-ray absorptiometry) scanning. Each of these methods has its advantages and disadvantages, and the choice of method depends on the purpose of analyzing the body composition and the availability of appropriate equipment.

What is and what is electrical bioimpedance?

Bioelectrical impedance (BIA) is a non-invasive method of measuring body composition that uses low-voltage electric current to measure body resistance. During BIA measurement, current is introduced into the body by electrodes placed on the hands and feet or on other parts of the body. Current flows through muscle, fat and bone tissues at different speeds because they have different electrical resistance.

Based on the electrical resistance measured during the BIA, the amount of muscle and fat mass in the body can be calculated. The BIA algorithm can also take age, gender, height and weight into account to calculate the amount of fat and muscle mass in individual parts of the body.

The BIA measurement is fast, non-invasive and painless, and the results are accurate and repeatable as long as the measurement is carried out in accordance with the appropriate rules. The disadvantage of BIA is that its measurement accuracy can be affected by various factors, such as hydration levels, physical activity levels and pre-measurement food and drink intake.

How do I prepare for the test?

Preparation for body composition analysis depends on the method that will be used. For some methods, such as weight measurement or waist circumference measurement, no special preparation is required. However, for more advanced methods, such as DXA scanning or bioelectrical impedance (BIA), some preparation may be necessary. Here are some general recommendations for preparing for the study of body composition analysis:

  1. Eat a normal breakfast or lunch a few hours before the test and avoid eating immediately before the test.
  2. Avoid alcohol and caffeine for at least 24 hours before the test, as they may affect your body’s hydration level.
  3. Avoid strenuous exercise for at least 24 hours before the test, as this may affect water and electrolyte levels in the body.
  4. Maintain a regular level of hydration, but avoid excessive amounts of fluids before the examination.
  5. Remove your jewellery and do not wear any metal objects during the test as they may affect your BIA measurement results.
  6. If necessary, perform an examination on an empty stomach, as directed by a doctor or specialist.

It should also be remembered that before any examination you should consult your doctor or specialist and ask for recommendations on how to prepare for the examination of body composition analysis.

What will we learn by analyzing the body composition?

Analysis of body composition allows you to obtain detailed information about the quantity and quality of body fat, muscle mass, bone and water in the body. With this study, you can learn about different aspects of health and fitness, such as:

  1. Overall body weight – body composition analysis allows you to accurately determine your body weight, which can be useful for setting goals related to weight loss or gain.
  2. Body composition analysis allows to determine the amount of body fat in the body, which is important for assessing the risk of obesity-related diseases.
  3. Muscle mass – analysis of body composition allows you to determine the amount of muscle mass in the body, which is important for people who want to increase their strength and physical condition.
  4. Body fat breakdown – body composition analysis can determine where body fat is located, which may be important for assessing the risk of heart disease and diabetes.
  5. Hydration level – Some body composition analysis methods, such as bioelectrical impedance (BIA), allow you to determine the level of water in the body, which may be important for maintaining electrolyte balance and hydration.

Body composition analysis can also help you set your training and nutrition goals and monitor your progress towards these goals. For diseases associated with body composition disorders, such as anorexia or obesity, body composition analysis can be an important diagnostic and therapeutic tool.

Why is it worth doing a body composition analysis?

There are many reasons why it is worth doing a body composition analysis. Here are some of them:

  1. Determining training and nutritional goals – body composition analysis allows you to determine the current body composition and helps to set goals related to fat reduction, muscle mass increase or overall fitness improvement.
  2. Monitoring your progress – Regular body composition analysis allows you to monitor your progress towards your training and nutrition goals, which can be motivating and helpful in adjusting your training and nutrition program.
  3. Diagnosing diseases associated with body composition disorders – Body composition analysis can help diagnose diseases associated with body composition disorders, such as anorexia or obesity.
  4. General Health Assessment – An analysis of body composition can help you assess your overall health and risk of diseases associated with obesity or underweight.
  5. Evaluation of the effectiveness of training and nutrition programs – analysis of body composition allows to evaluate the effectiveness of training and nutrition programs and to adjust them if necessary.
  6. Personalization of the nutrition plan – thanks to the analysis of body composition, you can personalize the nutrition plan, taking into account the individual needs of the body.

The conclusion is that body composition analysis is an important tool in making decisions about health and fitness. It can help you set training and nutrition goals, diagnose diseases associated with body composition disorders, and monitor progress towards these goals.

How does the Tanita BC-1000 body composition analyzer work?

The Tanita BC-1000 Body Composition Analyzer works on the principle of bioelectrical impedance, i.e. measuring the electrical resistance of the body at the flow of a small electric current. The device is equipped with electrodes, which are placed under the feet of the user.

During the measurement, the device sends a small electrical current through the body and then measures the electrical resistance that this current encounters as it passes through muscle and fat tissues. Based on this measurement, and taking into account the user’s age, gender, height and weight, the device calculates the percentage of body fat, muscle mass, water and basal metabolism.

The Tanita BC-1000 also allows you to transfer measurement data to a special application on your computer or smartphone using ANT+ wireless technology. This allows you to monitor your results and progress over time and adjust your training and nutrition goals to your individual needs and measurement results.

Who performs the body composition analysis study?

Body composition analysis can be performed by a variety of professionals, including doctors, dieticians, personal trainers, physiotherapists, as well as by people qualified to operate specialized body composition measuring devices such as a bioimpedance meter.

Depending on the measurement objectives and individual needs, the choice of the specialist or the location where the test will be performed may vary. If the examination is performed for diagnostic or therapeutic purposes, it is recommended to consult a doctor or other specialist appropriate for the disease or condition in question. However, if the test is performed for training and nutrition purposes, it may be a good choice to use the services of a dietitian or personal trainer, who have knowledge of body composition and its impact on the effectiveness of training and nutrition.

In any case, it is important that the study of the analysis of the body composition is carried out by a qualified specialist, who will accurately carry out the measurement and will be able to properly interpret the results.

Why is it worth measuring body fat at a dietitian?

Measuring body fat with a dietitian can have many benefits, both in terms of health and in terms of achieving diet and exercise goals.

Measuring body fat allows you to determine the ratio between body fat and muscle tissue. This is important information because body fat is associated with the risk of metabolic diseases such as diabetes, heart disease, and also endocrine system problems. For people who have an excessive amount of body fat, this measurement may be a signal to take action to reduce weight and improve health.

Measuring body fat with a dietitian can also help you achieve your diet and exercise goals. Based on the results of the measurement, the dietitian will be able to adjust the diet and training plan to the individual needs and goals of the person. Thanks to this, it is possible to determine the optimal calorie balance, the amount of protein, carbohydrates and fat in the diet and the appropriate amount of training, which will allow to increase muscle mass or reduce body fat.

It is also worth remembering that measuring body fat at a dietitian is often more accurate than measuring yourself at home. The measurements made by the dietitian are more accurate and allow a better understanding of the results and the relationships between individual indicators.
