How body composition measurement works
A body composition measurement shows the amounts of muscle, fat and fluid in the body and how they are distributed in different body parts. The measurement is performed at Puhti’s self-service measurement point with an InBody 770 device. Order the body measurement online and follow your results in the MyJournal service.
A smooth visit consists of three parts: correct preparation, clear instructions at the measurement point and reviewing the results in MyJournal.
Preparation and measurement step by step
When should the measurement be postponed?
The most reliable result is obtained when you feel normal and your fluid balance is in order. Postpone the measurement if you have a fever, a stomach bug, or if you otherwise feel weak. Also avoid the measurement if you have consumed a lot of alcohol in recent days or have a hangover. When you feel normal again and conditions are stable, the measurement will give a more reliable result.
During pregnancy, the measurement is not recommended. Individuals with an implanted electronic medical device, such as a pacemaker, should avoid the measurement.
Results and the MyJournal report
After the measurement, you will receive a clear, easy-to-read MyJournal report. It includes key results such as body fat percentage, visceral fat level, muscle balance, fluid balance, body type, segmental fat analysis and phase angle.
The report includes a results interpretation section that explains what the numbers mean in practice. Follow your progress in MyJournal and keep the measurement conditions the same so you can clearly see changes.

Taking a body composition measurement with Puhti is easy. Start by purchasing a measurement kit from Puhti website. Read the preparation instructions carefully before taking the measurement.
When you arrive at the measurement point, open the door and go to the device. Check the measuring device that the ID and mobile phone number shown on the screen are correct. Do not change the mobile phone number. Clean the devices with cleaning wipes before use.
Remove socks and outerwear. The device automatically subtracts one kilogram from the measurement result.
The measurement process proceeds as follows:
- First measure your blood pressure.
- Then step on the device and follow the instructions it gives.
- Finally, measure the grip strength of your hands.
Step off the device, and the measurement will end automatically. Clean the devices again with cleaning wipes after use. You will receive a text message notification when the results are ready. You can view your results in the MyJournal report.
If the grip strength meter is displaying pounds instead of kilograms, you can switch the unit as follows:
- Turn on the power of the grip strength meter.
- Squeeze the handle with half of your strength while, at the same time, briefly pressing the device’s power button (for about 1-2 seconds).
- This action will change the measurement unit from pounds to kilograms.

Puhti’s body measurement, also known as the InBody 770 measurement, is an advanced and precise method that provides detailed information about body composition. The measurement includes over 50 values that reliably and accurately analyze, among other things, body muscle mass, body fat percentage, fluid balance, and an overall assessment of the body, presented in a clear report.
Puhti’s body measurement includes three measurements depending on the measurement point:
- InBody body composition measurements
- Blood pressure measurements
- Hand grip strength measurements
Yes. Puhti’s body composition report includes over 50 measurement results. Each result in the report is clearly explained so that you understand what the numbers mean in practice.
Bodymaja will be integrated into Puhti’s result report in November 2025. After this, you will see all your results on the Oma Puhti report.

Note! The ID and mobile phone number must be the same on the InBody device. If you have entered something other than your ID number in the mobile phone field, the result cannot be found in the system and will not appear in your Oma Puhti report. In this case, we recommend repeating the measurement.
You can find your personal ID number at oma.puhti.fi under “Body measurements”.
The ID used on the measurement device changes between measurements. Use this changing ID code to identify yourself on the device instead of your phone number.
If the device was not connected via Bluetooth and you did not manually add the results, the results will not be delivered to you. You will need to visit the measurement point again.
If the device was not connected via Bluetooth and you did not manually add the results, the results will not be delivered to you. You will need to visit the measurement point again.
If you accidentally used your phone number on the device, your results have been forwarded to customer service for manual processing. These results will be available to you within approximately 2 days.
If you accidentally pressed the “guest measurement” button on the device, your results will not be saved in the system. In this case, you will need to repeat the measurement.
Puhti is not responsible for the InBody app; it is provided by the device manufacturer. You can still transfer results from our devices to the app as follows:
- Keep your mobile device close enough so you can reach it without stepping off the device.
- Perform the measurement as usual.
- At the end, scan the QR code on the screen to send your results to the app. If you step off the device, the screen resets and the QR code disappears.
Puhti is not responsible for the app’s technology, development or compatibility, and does not guarantee that results will be available in the InBody app.
It shows how much fat, muscle and water your body contains and how they are distributed across body segments. The report includes key metrics such as visceral fat (fat around internal organs), a muscle–fat assessment, fluid balance and waist-to-hip ratio. It also highlights asymmetries and muscle balance to help you target training and daily changes. Results are presented clearly to make goal-setting and follow-up easy.
Yes. InBody measurement is reliable when performed according to instructions and repeated under similar conditions. The method is based on multi-frequency BIA used widely in healthcare, and the devices are medical devices.
InBody 770 is a medical device (MDD/93/42/EEC) that measures body composition accurately and quickly using a patented method.
- Measurement time is 60 seconds.
- Measurement frequencies 1, 5, 50, 250, 500, 1000 kHz allow assessment of different tissues.
- Wide operating range: weight 10–270 kg, height 95–220 cm, age 3–99 years.
In total, 30 impedance measurements are taken at six frequencies across these segments: right arm, left arm, trunk, right leg and left leg.
Bioelectrical impedance analysis (BIA) measures electrical conductivity – the varying resistance alternating current encounters in different parts of the body. Different tissues respond differently to current. Body water conducts electricity very well, while fat acts like an insulator.
