Body recomposition: fat down, muscle up
During recomposition, weight often stalls while fat drops and muscle rises. Vita separates those curves; add Elio in the same Chutex app for sleep and recovery signals.
Recomposition: when the scale lies
Athletes and returning lifters often see stable weight while body fat falls and muscle rises. Only composition tracking reveals the swap.
Vita plots fat mass and muscle mass on separate curves. Nora highlights weeks where weight is flat but composition improves — the signal most basic scales miss.
Training and nutrition alignment
Protein targets, progressive resistance training and sleep are the classic trio. Elio shows whether recovery supports your calorie surplus or deficit.
Export PDF reports before nutritionist or physio appointments to show 90-day composition trends.
Bio-impedance limits you should know
Bio-impedance analysis (BIA) estimates body composition from electrical resistance. Results shift with hydration, recent meals, exercise, alcohol and time of day. Vita is designed for consistent morning weigh-ins on a hard flat surface, barefoot and dry.
Vita does not replace DEXA, MRI or clinical blood work. Trends over 6–24 months matter more than a single reading. If you have oedema, pregnancy or an implanted cardiac device, follow clinician guidance — BIA is contraindicated with pacemakers.
Segmental analysis (arms, legs, trunk) helps spot asymmetry during rehab or sport, but remains indicative. Pair Vita with Elio for sleep and recovery context, and export PDF summaries for your clinician when needed.
How Vita fits the Chutex ecosystem
Vita is the home anchor for body composition. Elio adds wrist-based sleep, HRV and activity. Nora AI crosses both signals for nutrition and recovery coaching in one Chutex app.
Chutex Health data for Vita is hosted with an HDS-certified provider in France (GDPR). 24/7 physician teleconsultation and Chutex Care teleassistance are France-only — US and UK users rely on local care pathways.

What Vita does — and what it does not do
Vita does
- Estimate weight and body composition (fat, muscle, water, visceral fat) via bio-impedance.
- Auto-sync weigh-ins over Wi-Fi to the Chutex app (up to 8 profiles).
- Drive weight goals, calories and macros with Nora AI and 6/12/24-month trends.
- Combine with the Elio band in the same app to cross body composition and wrist signals.
- Allow controlled sharing with family, coach or professional (PDF export).
- Host data on Free Pro / XPR HDS-certified infrastructure (GDPR) — CHUTEX as data controller.
Vita does not
- Provide a medical diagnosis.
- Guarantee clinical-grade accuracy like DEXA.
- Measure blood glucose like a glucometer (indicative estimation with Elio only).
- Replace a dietitian, physician or medical advice.
- Work for pacemaker or implanted stimulator wearers (BIA contraindication).
- Promise guaranteed weight loss.
Wellness connected scale. BIA estimates are indicative and vary with hydration, meals, recent exercise and time of day.
How to get comparable measurements
- Weigh in the morning, fasted, after bathroom, dry feet.
- Same time daily when possible.
- Avoid immediately after exercise or a large meal.
- Flat, hard, stable surface.
- 12 measurement families, 50+ data points and trends per weigh-in.
Services by country
Vita subscription by market
The Vita bio-impedance scale is sold across Europe. Nora AI coach and the Chutex app are included. Some health services are France-only.
24/7 physician teleconsultation and HDS hosting apply to eligible accounts in France only. Outside France, use local care pathways and emergency numbers (911 / 999 / 112). Vita is a wellness scale — not a medical diagnostic device.
Frequently asked questions
How long does recomposition take to show on Vita?
Most users see separable fat and muscle curves within 4–8 weeks of consistent weigh-ins and training, though individual response varies.
Is Vita a medical device?
No. Vita is a wellness connected scale. BIA estimates are indicative and not intended to diagnose disease. Consult a clinician for symptoms or treatment decisions.
Can I use Vita with a pacemaker?
No. Bio-impedance is contraindicated for pacemaker or implanted stimulator wearers. Use weight-only mode only if your clinician explicitly approves an alternative method.
How often should I weigh in?
Daily morning weigh-ins after bathroom, before breakfast, give the most comparable BIA trends. Nora uses rolling averages to smooth day-to-day noise.
Does Vita sync automatically?
Yes. After initial 2.4 GHz Wi-Fi setup, each weigh-in syncs to the Chutex app without QR codes. Bluetooth is available for phone pairing.
Is 24/7 physician included in the US?
No. Medical teleconsultation bundled with Chutex Health is France-only unless a local offer is explicitly published. In the US use 911 and your existing care team.
