What is a dietitian?
A dietitian-nutritionist is a healthcare professional who specialises in diet. They assess nutritional needs, build personalised meal plans and support both healthy people and patients with medical conditions (diabetes, obesity, digestive disorders, undernutrition). Their role is both preventive and therapeutic.
What a dietitian does day to day
- Carry out a dietary assessment (habits, needs, goals, health status).
- Build personalised meal plans and suitable menus.
- Provide nutritional follow-up for patients with medical conditions, working with the medical team.
- Run therapeutic education and prevention activities.
- Design and oversee menus in catering for institutions (hospitals, care homes, schools).
- Inform the public and raise awareness of a balanced diet.
Skills and qualities required
- Solid knowledge of physiology, biochemistry and nutrition.
- Good listening skills and communication skills, without judgement.
- Teaching skills: being able to explain things simply and motivate change.
- Scientific rigour and keeping up to date (recommendations change).
- Ability to adapt to varied groups (children, athletes, older people, patients).
How to become a dietitian: training and career path
Entry to the profession requires one of the qualifications set by ministerial order: the BTS Diététique et nutrition or the BUT Génie biologique (Diététique et nutrition pathway). Here is the route:
A general baccalauréat (biology or physics-chemistry specialisms) or a STL/ST2S technological baccalauréat makes it easier to get onto the course.
Both allow you to practise. The BTS, reformed by an order of 27 November 2024, takes two years, with 20 weeks of placements and a first exam session in 2027; you can study for it at a college, through work-based learning or by distance learning, see our comparison of distance-learning dietetics BTS courses. The BUT takes three years at a university institute of technology (IUT).
Several weeks of placements in hospitals, institutional catering and private practice provide the essential practical experience.
Once qualified, the dietitian registers with the health authorities and then works as an employee or sets up in private practice.
What does a dietitian earn?
€1,800
€2,700
€4,000
Income in private practice varies widely depending on client base, location and specialism. A dietitian consultation is generally not reimbursed by the French national health insurance (Sécurité sociale) outside the hospital pathway, but more and more complementary health insurers (mutuelles) now cover it.
Career opportunities and places of work
- Hospitals and clinics: caring for hospital patients.
- Care homes and institutional catering: menu design, preventing undernutrition.
- Private practice: one-to-one consultations.

Career progression
With experience, a dietitian can specialise (sports nutrition, paediatrics, obesity, eating disorders, micronutrition), move into management roles (healthcare manager, catering manager), build a private practice, or turn to teaching, research or health content creation.
