Nutritionist training: routes and careers in 2025

Feeling lost among the routes to becoming a nutritionist or dietitian? Here we will try to clear up the misunderstandings about training, both regulated (such as the BTS Diététique, with 20 weeks of placements, and the EDNH programmes from Bac+3 to Bac+5) and unregulated. Discover the differences between a doctor specialising in nutrition (Bac+9 to Bac+11), a dietitian (Bac+2 or Bac+3) and a nutrition coach, as well as the career options in hospitals, the food industry or sport. We also look at funding options (CPF, work-study) and the specialisms that can boost your career, such as sports nutrition or nutrition for older people. (Bac+N means N years of higher education after the French baccalaureate.)

Nutritionist, dietitian, coach: what are the differences?

The doctor specialising in nutrition: a compulsory medical route

A doctor specialising in nutrition follows a long and demanding path. It starts with medical studies (6 to 9 years), made up of a common core followed by a specialisation. The specialisation is obtained through a residency in endocrinology-diabetology-nutrition or through a specific university diploma. Only this professional can diagnose nutrition-related conditions and prescribe drug treatments.

The nutrition doctor’s advanced medical skills allow them to assess patients’ nutritional status, draw up personalised treatment plans, and work with other specialists in a multidisciplinary setting.

The dietitian: a paramedical health professional

The title « nutritionist » on its own is not regulated in France, but its use by a specialist doctor clearly distinguishes them from the dietitian, who follows separate paramedical training.

The dietitian is a regulated health professional holding a specific qualification (BTS Diététique, professional bachelor’s degree). Their role is to make dietary assessments, deliver nutritional care and develop prevention programmes. They work on medical prescription or in prevention for a variety of groups: athletes, children, older people, pregnant women.

The dietitian adapts diet to specific needs, but cannot make a medical diagnosis or prescribe drugs. They can work in hospitals, in private practice, in companies or in catering.

The nutrition coach or adviser: an unregulated career

The nutrition coach is not a regulated health professional. Their scope is limited to supporting healthy people who want to improve their eating habits. Training to become a coach is varied but not standardised, and is often short and non-degree.

This professional can neither diagnose nor treat medical conditions. Their role is mainly preventive: they support changes in eating behaviour, draw up personalised meal plans and raise awareness of a balanced diet. To practise legitimately, certified training is nonetheless recommended.

Training to become a dietitian

The BTS Diététique et Nutrition: the reference route

The BTS Diététique et Nutrition is the main qualification for becoming a dietitian. It has replaced the former BTS Diététique since November 2024. Completed over two years (first year in 2025, second in 2026), it is open to holders of a baccalaureate, preferably in science for the foundations in biology and chemistry.

The courses cover nutritional assessment, managing therapeutic diets and health education. Students learn to adapt diet to specific needs (medical conditions, athletes, older people) and to design prevention programmes. The training includes 20 weeks of placements:

• 4 weeks in catering (menus, health standards)
• 10 weeks in a therapeutic setting (patient follow-up)
• 6 weeks in public health (balanced diet campaigns)

Practical training is at the heart of the BTS Diététique, with 20 weeks of compulsory placements in varied environments to guarantee complete, professionalising field experience.

Available by distance learning through Cned (the French national distance-learning centre), the course offers personalised support and a 24/7 platform. Career options include hospitals, catering, the food industry or private practice. The BTS also trains you for nutrition advisory roles in companies or local authorities.

The BUT Génie Biologique, dietetics and nutrition pathway

The BUT Génie Biologique (a bachelor-level degree) is a three-year alternative, taught in IUTs (university institutes of technology). It prepares you for careers similar to the BTS, with an in-depth scientific approach to biochemistry, pathophysiology and food risk management. Students also study microbiology, food safety and the interactions between nutrition and public health.

The compulsory placements (24 to 32 weeks) include a 14 to 16 week placement in a therapeutic setting. In the second year, an 8 to 12 week placement completes the training. Work-study is possible in the third year. Career options include:

• Healthcare establishments (hospitals, clinics)
• Catering (designing suitable menus)
• R&D in the food industry (formulating balanced meals)
• Sports or spa centres (nutritional support)

To get onto the BUT, a general baccalaureate (life and earth sciences, physics-chemistry) or a technological one (STL, ST2S) is required. Admission is by application or interview. Further study at master’s level or in an engineering school is possible, such as specialist diplomas in nutrition or the food industry. The programme includes certifications such as Therapeutic Patient Education (ETP) or food hygiene, boosting employability. IUTs such as the one at Clermont Auvergne offer this pathway, with a pass rate of 79% over two or three years.

Continuing your studies: bachelor, master and specialist diplomas

Bachelors and masters in nutrition

The École de Diététique et Nutrition Humaine (EDNH) offers a Bachelor (Bac+3) and a Master (Bac+5) in human nutrition. For 25 years, these programmes have trained professionals able to support a wide range of people: athletes, vulnerable or pregnant people, or those in health prevention. The school welcomes students from all starting levels, with an emphasis on human biology (anatomy, metabolism) and the psychology of eating.

The courses include the study of nutrients, social practices and food safety. The active teaching method puts lectures beforehand so that class time is free for case studies. Placements start in the first year, with up to 6 months in the final year. The 8 campuses (Aix-Marseille, Paris, Toulouse and others) make it geographically accessible. Applications are made outside Parcoursup (the national university applications platform), with open days to guide candidates towards work-study.

University and engineering programmes

Universities and grandes écoles (elite higher-education institutions) offer Bac+5 specialisms. At Sorbonne Université, the Master in Integrative Biology and Physiology (BIP), Nutrition, Quality and Health (NQS) pathway trains you in human nutrition, R&D and health safety. Available as work-study, this diploma prepares you for posts in research or public health bodies.

AgroParisTech offers two advanced programmes: the Certificat de Spécialité (CS) in Sciences and technologies of biology, nutrition and human food, aimed at managers who want to build nutritional issues into food strategies. The « Sciences and technologies of biology, nutrition and human food » specialisation in the 3rd year of the engineering cycle trains experts in food safety and innovation.

UniLaSalle offers a food industry and health engineering programme, accredited by the CTI (the French engineering qualifications commission). On the Beauvais campus, students learn to design innovative products (functional foods, alternative proteins) with 10 months of compulsory placements and international mobility. The diploma opens the door to careers in R&D, quality or sustainability in the food industry.

The nutrition sector is booming thanks to demand for personalised diets, sustainable foods and technologies (3D printing, microbiome analysis). Nutritionists work in the food industry, NGOs and public policy, with prospects in international nutrition or supplements. University and engineering programmes offer varied career paths, from the field to management positions.

Which nutrition training is right for you?

To choose your path, define your goals. If you want to prescribe diets and diagnose conditions, the career of doctor specialising in nutrition requires a regulated medical degree in France, followed by a specialisation in endocrinology or nutrition. To support patients in following a diet or to work in catering, dietitian training (BTS or BUT) is the right fit. Finally, a bachelor or master in nutrition (unregulated) gives access to fields such as sports nutrition or corporate consulting.

Training route	Title obtained	Qualification level	Length of study	Main prerequisites	Estimated cost	Main career options
Medical studies + specialisation	Doctor specialising in nutrition	Bac+9 to Bac+11	9 to 11 years	Baccalaureate + passing PASS/L.AS (the first-year medical entry routes)	Public university fees	Hospital, clinic, private practice (diagnosis, prescription)
BTS Diététique et Nutrition	Dietitian	Bac+2	2 years	Baccalaureate (science recommended)	Public (low) or private (several thousand € a year)	Hospital, catering, private practice, food industry
BUT Génie Biologique	Dietitian	Bac+3	3 years	Baccalaureate (technological or general science)	Public university fees	Similar to the BTS, with access to senior technician posts
Bachelor/Master in Nutrition (EDNH type)	Nutritionist / Nutrition expert (unregulated)	Bac+3 / Bac+5	3 to 5 years	Any type of baccalaureate	Private school (several thousand € a year)	Industry, marketing, communication, consulting, sports nutrition

The table compares the routes. Medical training (9-11 years) authorises medical prescription. Dietitian qualifications (BTS/BUT) give quick access to the job market at a moderate cost. Unregulated nutrition training (bachelor/master) targets fields such as sports nutrition, but without the right to make a medical diagnosis.

Study options and funding for your training

Studying remotely or through work-study

Distance learning suits people balancing study with work or geographical constraints. From 2025, Cned offers a 100% online BTS Diététique et Nutrition, open after a baccalaureate (science advised), with personalised tutoring, virtual classes and 20 weeks of placements (therapeutic setting, catering, public health). It prepares you for varied career options: hospitals, local authorities or the food industry. Work-study combines theory and practice with a salary. EDNH offers Bac+2 to Bac+5 programmes (BTS, Bachelor, Master) on a 2 days/3 days rhythm, with 8 campuses in France (Paris, Lyon, Bordeaux and others). Sorbonne Université offers an NQS Master as an apprenticeship (15 days/15 days rhythm), including a placement abroad. Work-study guarantees rapid job entry: 100% hired within 2 months for the NQS Master.

How to fund your nutrition training

Costs vary with the level and the institution. Public universities (Sorbonne Université) are cheaper than private schools (EDNH, Cned). Funding options:

• CPF (the French personal training account): Some qualifications (such as the BTS) are eligible for using your credits. For example, a BTS Diététique costs around €8,000 to €10,000 at a private school, part of which can be funded through the CPF.
• France Travail (the French public employment service): Jobseekers can obtain an AIF (individual training aid) under conditions for approved courses, particularly work-study. Amounts depend on the project and regional priorities.
• Work-study: The employer covers the fees and pays a salary. Example: a work-study student on the NQS Master at Sorbonne Université receives between 70% and 100% of the minimum wage (SMIC) depending on age and level.
• Personal funding: Student loans (e.g. Crédit Agricole, Boursorama) or staggered payment plans for ineligible courses. Some schools offer payment over 12 months.

Work-study (EDNH or Sorbonne Université) offers professional experience and a recognised diploma. The programmes often include company projects, boosting employability. Sorbonne Université emphasises innovation and the environmental issues around food, such as tackling waste or promoting « health foods ».

What are the career options after nutrition training?

The sectors that recruit nutrition experts

Nutrition and dietetics graduates work in a variety of fields. According to AgroParisTech, 30% of graduates become nutrition engineers, and 20% go into R&D. These careers meet growing needs for nutritional expertise, particularly in personalising diets and in health innovation.

• The healthcare sector: Hospitals, clinics, home care or private practice. Dietitians draw up diets for conditions such as diabetes or digestive disorders, often in collaboration with doctors or multidisciplinary teams.
• Catering: Schools, companies or social care settings. Professionals optimise menus for children, older people or dependent people, ensuring nutritional balance and compliance with regulations (e.g. balanced meals in nurseries).
• The food industry and pharmaceuticals: R&D to create enriched products (e.g. iron-fortified cereals), quality control to validate nutrition claims, or advice on marketing strategies based on the benefits of foods.
• Public health: Local authorities or bodies such as the PNNS (the French national nutrition and health programme), with campaigns such as « Eat 5 fruit and vegetables a day » or school programmes to tackle obesity.
• Sport: Supporting athletes with suitable energy intakes, whether individual athletes or professional teams (e.g. diet for a rugby player or swimmer).
• Research and teaching: Laboratories or specialist courses, on subjects such as the effects of antioxidants or the links between diet and neurodegenerative diseases.

Specialisms to refine your career plan

Post-initial training lets you specialise. Sorbonne Université offers a DIU (inter-university diploma) in nutrition for older people, useful for managing undernutrition. This diploma covers topics such as protein needs to prevent muscle loss in older people. Unicancer runs training on nutrition in oncology, for cases such as loss of appetite linked to chemotherapy or iron deficiency after digestive surgery.

Cross-disciplinary routes also exist, such as the WASH’Nutrition course for humanitarian nutrition, focused on conflict zones or developing countries. Other courses target fields such as sports micronutrition (e.g. vitamin D supplements for ultra-trail runners), FODMAP diets for sensitive guts, or circular eating (reducing the carbon footprint without sacrificing nutrient intake). These specialisms, often online or work-study, let you meet specific needs such as managing eating disorders or supporting people after bariatric surgery.

Each of the nutrition careers (doctor specialising in nutrition, dietitian, coach) requires suitable training, from the BTS to the master. The choice depends on your career goals and your regulatory commitment. The varied career options (health, food industry, research) offer solid prospects for a career centred on wellbeing and prevention.

FAQ

What do you need to study to become a nutritionist?

To become a nutritionist, you must follow a medical route. The journey breaks down into several stages: baccalaureate, then PASS or L.AS to gain access to medical studies. After 6 to 9 further years of study, a residency in endocrinology-diabetology-nutrition or a specific university diploma in nutrition is required. Only specialist doctors can use the title of nutritionist, which guarantees advanced medical skills and the ability to make diagnoses.

Can you work as a nutritionist without a medical degree?

No, the title of nutritionist is reserved for specialist doctors. However, other nutrition careers exist without a medical degree. The dietitian gets a BTS or BUT in dietetics (Bac+2 to Bac+3). The nutrition coach or adviser has no compulsory qualification but certified training is strongly recommended to guarantee reliable advice. These professionals do not have the same powers as a doctor specialising in nutrition.

What is the difference between a nutritionist and a dietitian?

The nutritionist is a doctor specialising in nutrition, holding a medical degree and a specialisation in endocrinology-diabetology-nutrition. They can make diagnoses and prescribe medical treatments. The dietitian is a paramedical professional holding a BTS or BUT in dietetics (Bac+2 to Bac+3). Their role is to make dietary assessments, deliver dietary care and develop nutrition education programmes, always within the framework of a medical prescription or prevention.

What route is there for a career change into nutrition?

Several options are open to an adult wanting to change career. The BTS Diététique et Nutrition (Bac+2) is available remotely through Cned, with 20 weeks of compulsory placements. The BUT Génie Biologique (Bac+3) is another route through the universities.
