How to open a nutrition practice in 2026: the complete guide

1. Who can practise as a nutritionist: qualifications and licensing

In Italy, independently designing diets is reserved for three professionals: the physician (including dietologists), the biologist-nutritionist (a suitable master's degree + state exam + registration with the National Register of Biologists, Section A) and the dietitian (a degree in dietetics, a healthcare profession, registered with the TSRM-PSTRP register). Most countries have equivalent regulated titles.

A "nutritionist" without one of these titles cannot design diets: they can provide general nutritional education, within precise limits. The biologist-nutritionist, in particular, designs diets independently for healthy individuals and, for individuals with pathologies, after a physician's assessment of the physio-pathological conditions; they do not make diagnoses or prescribe drugs.

2. Business registration: tax code, regime and costs

• Registration: free if done yourself on the tax authority's website; €100–300 through an accountant (recommended).
• Activity/tax code: in Italy, the reference for the biologist-nutritionist is 72.11.00 (Research and development in biotechnology); 86.90.29 (independent paramedical activities) has also often been used. Your accountant indicates the one best suited to your profile.
• Flat-rate regime: up to €85,000 in revenue, a 15% substitute tax (5% for the first 5 years if you meet the new-business requirements). For both codes the profitability coefficient is 78%.
• Social security: biologists pay into ENPAB, dietitians generally into the INPS Separate Management scheme. Budget for the annual contributions from year one.

3. Professional insurance (mandatory)

Professional liability insurance is mandatory for healthcare professionals. For a nutritionist starting out it costs roughly €100–300 a year. This is not where to cut corners: it covers your professional work, including online services.

4. Privacy and GDPR: the documents you need from day one

• A privacy notice for patients (that also mentions the digital tools and any AI used);
• An engagement letter / informed consent to the service;
• A record of processing activities;
• Data processing agreements (GDPR art. 28) for every piece of software that touches patient data;
• Security measures: no diets sent by plain email or medical histories on Excel files on your desktop; use encrypted tools with controlled access.

5. In-person, online or hybrid practice?

An in-person practice gives authority and allows all instrumental measurements, but it involves high fixed costs (rent, furnishings) and a local patient base: it's ideal for those who already have an established business. The online model almost entirely eliminates fixed costs, opens up a national reach and offers maximum flexibility, with the limit of instrumental measurements: perfect for a low-cost start.

The most common model for those starting today is the hybrid one, which combines the advantages of both: a room rented by the hour (€30–50 for half a day in medical centres) for first visits and measurements, plus follow-up visits online. Low costs, wide reach and good flexibility make it suitable for most cases.

6. The tools to get started

To work professionally from day one you need four things: a calendar with online booking, a GDPR-compliant patient record, meal-plan creation and invoicing with submission to the health system. You can assemble them with 3–4 separate tools, or use a single platform like Cibus, with dedicated terms for students and recent graduates.

How much does a nutritionist earn?

Average market fees in Italy: first visit €70–130, follow-up visit €40–50, monthly programmes €100–200 depending on complexity. In a typical month with 15 first visits and 30 follow-ups the indicative total is €2,250–3,450 per month, plus ongoing programmes.

1. 1Specialisation: clinical niches (sports nutrition, diagnosed conditions, paediatric age) justify higher fees.
2. 2Digital presence: a well-kept profile on booking platforms and a good online reputation increase new patient acquisition.
3. 3Retention: real revenue is in patients who return. Automatic reminders and structured programmes reduce drop-offs.

Conclusion

Opening a nutrition practice in 2026 requires less capital than ever: the real barrier isn't financial, it's organisational. Those who start with digital processes from day one (bookings, GDPR, invoicing, AI) build an advantage that colleagues with 2010-era software won't recover.
