Body composition analysis
Understand what your weight doesn't show
In a few seconds, the Biody Xpert measures electrical impedance and estimates your fat mass, muscle mass and body-water distribution. Gabriela Ferent then interprets the results with you to tailor your nutritional support.
Painless measurement · About 10 seconds · Results explained during the consultation
- Included with in-person consultations
- About 10 seconds of measurement
- Available in all 3 cabinets
- Personal interpretation by the dietitian
The analysis is included at no extra cost during in-person consultations when clinically indicated and in the absence of contraindications. CNS reimbursement applies to the regulated dietetic consultation when applicable.
More useful markers than weight alone
Fat mass and lean mass
Follow their evolution to better understand weight variations.
Body water distribution
Look at total body water as well as intra- and extracellular distribution.
Phase angle
A complementary bioimpedance-derived indicator, interpreted alongside other clinical and nutritional data.
Three markers reviewed during the consultation
Muscle mass
Estimated muscle mass and how it changes over time.
Fat mass
Estimated fat mass, separate from total body weight.
Hydration
Intra- and extracellular distribution of body water.
Results are estimates from bioimpedance. They are interpreted by the dietitian and do not, on their own, constitute a medical diagnosis.
The device and the report, in practice
How does the measurement work?
Preparation
The dietitian checks that the conditions are appropriate and enters the necessary information.
Measurement
Seated, you hold the device between your hand and your foot. A very low-intensity, imperceptible current measures impedance within seconds.
Interpretation
Results are explained during the consultation and compared with previous measurements when available.
What you receive
- Visual summary of body composition
- Comparison with adapted reference values
- History to track progress between consultations
Anonymised example of a Biody Xpert report shown during the consultation.
Who may benefit
Weight loss
Check whether weight change corresponds mostly to fat, muscle or water variation.
Sport and fitness
Follow muscle-mass evolution and align nutritional goals with training and recovery.
Preserving muscle mass
Monitor muscle-mass evolution with age or in specific nutritional situations.
Preparing well for the measurement
- Avoid intense physical activity just before the consultation.
- Avoid heavy alcohol consumption the day before.
- Use the toilet before the measurement if possible.
- To compare several measurements, try to keep similar conditions from one consultation to the next.
- Mention medications or situations that may significantly affect hydration.
The measurement should not be performed in certain situations
- Pregnancy.
- Presence of an implanted or essential wearable electronic medical device, e.g. a pacemaker.
- Broken or irritated skin at the electrode contact points.
- Any other situation in which the dietitian judges that the measurement is not appropriate.
If in doubt, mention your situation when booking your appointment.
Frequently asked questions
No. The current used is very low intensity and completely imperceptible. The measurement is painless and requires no needles or products.
Understand your evolution, beyond the number on the scale
Book an in-person consultation. Your body composition will be analysed when indicated, then interpreted in the context of your goals, health and diet.
