What does a nutritionist actually do?

A nutritionist looks at what you eat and how it fits your life, then helps you make practical changes that suit your goals, such as more energy, steadier eating habits or a better balance of food. They explain, plan and support, and you do the doing. It is worth knowing that dietitian is a protected title and nutritionist is not, so it pays to ask about training.

What a nutritionist does

• Looks at your current eating. What you have in a normal week, when you eat, and what gets in the way.
• Asks about your goals. That might be more energy, eating more regularly, feeding a family, or supporting a sport or a lifestyle such as vegetarian eating.
• Explains the why. Plain-English information about food groups, portions and labels.
• Builds a plan with you. Small changes you can keep, not a strict list of rules.
• Checks in. You review what worked and adjust.

What happens at a first appointment

Expect a longer first session, often 45 to 60 minutes, in person or on video. You talk about your health, routine, likes and dislikes, and you may be asked to keep a food diary for a few days. Some nutritionists ask about sleep, stress and activity too, because they all affect how you eat. You usually leave with a few clear first steps rather than a whole new way of life.

Nutritionist, nutritional therapist or dietitian?

These are not the same. Dietitian is a protected title in the UK: dietitians must be registered with the HCPC, and they work with medical conditions, often in the NHS. Nutritionist is not a protected title, so anyone can use it. Some nutritionists are registered with the Association for Nutrition, and nutritional therapists may be on the CNHC register. Ask about their training and which register they are on.

How many sessions will I need?

It varies. Many people book a first appointment and two or three follow-ups a few weeks apart, so there is time to try changes between sessions. Some feel one session gives them enough to go on. It is fair to ask at the start how many sessions they would expect.

Roughly what does it cost?

Private nutrition appointments in the UK commonly start from £50 for a session, and often more in big cities. First appointments are usually longer and can cost more than follow-ups. Some nutritionists offer a free short call, and some sell packages. Check what is included, such as a written plan, and the cancellation terms.

Where it fits alongside NHS care and who it may not suit

A nutritionist can support healthy eating alongside the care you already have. If you have a medical condition, such as diabetes, a food allergy, coeliac disease or kidney problems, or you are pregnant, please talk to your GP first, and consider a registered dietitian. Please don't stop or change any medicine or prescribed diet because of a session. If you have a difficult relationship with food or think you may have an eating disorder, see your GP. A good practitioner will tell you if another route is better first.
