About the practice

Three offices in Luxembourg

The practice welcomes patients across Luxembourg from three offices. The main office is in Luxembourg-City. It sits at 74 Avenue de la Faïencerie, in Limpertsberg. It opens on Wednesdays from 1:00 PM to 6:00 PM. It is a short walk from the University of Luxembourg. Bus lines 3, 21 and 25 stop close by. Public parking is nearby at Glacis and Faïencerie.

Ettelbruck office

The Ettelbruck office is at 25 Grand-Rue, in the pedestrian centre. It opens on Tuesdays from 8:00 AM to 8:00 PM. It serves the north of Luxembourg. It is a short drive for people in Diekirch, Erpeldange, Feulen, Warken and Schieren. It also suits patients in Colmar-Berg, Vichten, Mertzig, Grosbous and Rambrouch. Belgian border patients from Bastogne, Neufchâteau, Libramont and Marche-en-Famenne can come too. Their INAMI fund covers the visit under EU cross-border rules.

Insenborn office

The Insenborn office is at 15 Burwiss, by the Upper Sûre Lake. It opens on Monday, Thursday and Friday from 9:00 AM to 7:00 PM. On Saturdays it opens from 9:00 AM to 2:00 PM. The Saturday slot suits working patients. This office serves Wiltz, Esch-sur-Sûre, Lultzhausen, Kaundorf, Bavigne and Boulaide. Child visits take place here in a family setting. Common topics are child weight, growth and food allergies.

Credentials and CNS accreditation

Gabriela Ferent runs every visit herself. She is a state-certified dietitian-nutritionist. She is licensed by the Luxembourg Ministry of Health. Her licence follows the law of 8 June 1999 on health jobs. She is a member of the ANDL, the national dietitian body. The practice is under contract with the CNS. On a doctor's prescription, the CNS pays 88% for adults. It pays 100% for children and for long-term conditions.

CNS-covered indications

The CNS covers many health goals. Type 1 and type 2 diabetes are on the list. So is obesity, at a BMI of 30 or more. A BMI of 27 also counts if you have a heart or metabolic risk. Eating disorders are covered too. High blood pressure and high cholesterol are on the list. So are kidney disease at stages 3 to 5, and dialysis. Cancer support and weight-loss surgery follow-up are covered. IgE food allergies, coeliac disease and IBD (Crohn's, ulcerative colitis) also qualify.

Evidence-based method

The method is strictly science-based. Advice draws on EFSA, ANSES and HAS guidelines. It also draws on the SFD, the ESC, ESPEN and the WCRF. Each plan is built for the person in front of us. It fits your medical, family and work life. It follows GDPR and full professional secrecy at all times.

Transparency commitment

The practice is fully transparent. No supplements are sold here. No protein powders, meal replacements or detox packs either. No pills, no branded gear, no add-ons. There are no deals with drug makers or supplement brands. There are no deals with weight-loss brands or shops. The only income comes from clear, published consultation fees.

Booking and contact

You can book online at any hour on Doctena. Pick your office, day and time in a few clicks. Choose your visit type: first visit, follow-up, urgent, or online. A reminder is sent by email and SMS the day before. You can also call +352 691 379 172. Or write to dieteticienne@conseildietetique.lu. Use these for any question, quote or medical referral.

Cross-border patients

Cross-border patients are welcome. French patients come from Metz, Thionville, Longwy and Verdun. Belgian patients come from Arlon, Bastogne, Virton and Neufchâteau. German patients come from Trier, Saarbrücken, Bitburg and Merzig. Their home fund covers the visit: CPAM in France, INAMI in Belgium, or the German Krankenkasse. EU rule 883/2004 makes this possible. Invoices carry every field needed for fast repayment: your name, insurance ID, ICD-10 code, date, duration, CNS act code, stamp and signature.

The first visit

A first visit lasts about sixty minutes. It starts with a full nutrition assessment. We review your medical history and any recent blood work. We look at weight, waist, body composition and activity level. We discuss your goals, your daily rhythm and your food likes and dislikes. We take culture, budget and cooking time into account. The plan is built for the person in front of us, not for a template. You leave the office with clear next steps you can start the same week.

Follow-up visits

Follow-up visits last thirty to forty-five minutes. We check progress against the goals set at the first visit. We adjust portions, meal timing and food choices based on what worked and what did not. We track weight trends, energy, digestion and lab markers when relevant. The rhythm of visits depends on the clinical need: weekly for weight-loss surgery follow-up, every two to four weeks for weight or diabetes work, every one to three months for maintenance and prevention. The CNS covers the number of visits your prescription allows.

Common reasons to book

Common reasons patients come to the office include stubborn weight gain after forty, prediabetes and type 2 diabetes, high cholesterol or triglycerides, high blood pressure, fatty liver, thyroid conditions, PCOS, menopause symptoms, IBS and reflux, food allergies, iron or vitamin D deficiency, sport nutrition for amateur and competitive athletes, pregnancy and postpartum nutrition, breastfeeding support, paediatric weight and growth, eating disorders, and post-surgery recovery. Every plan follows current European clinical guidelines.

Payment and CNS reimbursement

Payment is direct at the office by card, bank transfer or cash. You receive a detailed invoice on the spot. Adults with a medical prescription send the invoice and prescription to the CNS and are reimbursed 88% on their bank account, usually within two to three weeks. Minors and patients with a recognised long-term condition are reimbursed 100%. Private visits without a prescription are welcome and follow the same published fee list. There are no hidden costs and no upsell of products or programmes.

Hours and telehealth

The practice keeps hours that fit real working life in Luxembourg. Early morning slots are available in Ettelbruck on Tuesdays. Evening slots run until 7:00 PM in Insenborn on Monday, Thursday and Friday, and until 8:00 PM in Ettelbruck. Saturday morning slots in Insenborn cover patients who cannot leave work during the week. Video consultations on Doctena are available for follow-up visits and for cross-border patients who cannot travel to the office.

Confidentiality and GDPR

Every consultation respects strict medical confidentiality and full GDPR compliance. Health data is stored on European servers, encrypted at rest and in transit, and never shared with third parties without written consent. You can request access, correction or deletion of your file at any time. Communication with your GP, endocrinologist, cardiologist or gastroenterologist is only made with your signed authorisation, and always in the interest of coordinated care.

Useful resources

Useful links: the fees and CNS reimbursement page lists every act code and the exact amount refunded. The specialisations page details how each clinical area is handled: diabetes, cholesterol, weight loss, IBS, thyroid, menopause, sport, pregnancy. The interactive tools section offers a metabolism test, a visceral fat calculator, a healthy-basket game and a food-cravings roulette to support the plan between visits. The transparency page explains the funding model and the strict no-supplement policy.

For prescribing doctors

For prescribing doctors: a printable one-page prescription memo is available on the site. It lists the CNS act codes, the number of sessions per indication, and the wording required for full reimbursement. GPs, endocrinologists, cardiologists, gastroenterologists, paediatricians and psychiatrists can send referrals directly to dieteticienne@conseildietetique.lu. Feedback letters after the first visit and at each key milestone are sent back to the prescriber with the patient's written consent.
