The problem

Anyone can call themselves a “nutritionist”.

Plenty of coaches and influencers will sell you a plan. Very few are qualified clinicians. Dietitian is the regulated title - that is the difference between a proper assessment and a template.

  • Weight that will not shift?

    A dietitian builds a plan around your metabolism, medication and life - not a crash diet you cannot keep.

  • A diagnosis that needs nutrition?

    Diabetes, IBD, coeliac, CKD and liver disease all need condition-specific dietary care from a specialist RD.

  • Training seriously?

    Sports RDs cover fuelling, hydration, recovery and body composition - properly, not from a supplement seller.

What it covers

The reasons people see a dietitian.

Nutritional assessment answers very different questions. These are the reasons patients seek assessment most often.

  • Weight management

    Sustainable weight loss or gain built around your life - not a crash plan you cannot maintain.

  • Micronutrient deficiencies

    Iron, B12, vitamin D and more - tested and corrected properly, not guessed at with a multivitamin.

  • Athlete performance

    Fuelling, hydration, recovery and body composition tuned to your sport and training load.

  • Disease-specific (diabetes, CKD, liver)

    Evidence-based plans for type 2 diabetes, kidney disease, liver disease and more.

  • GI conditions (IBS, IBD, coeliac)

    FODMAP, exclusion and gluten-free plans supervised by a specialist gastro dietitian.

  • Vegan/vegetarian planning

    A complete, adequate plant-based diet - protein, iron, B12, omega-3 and calcium properly covered.

  • Paediatric growth

    Feeding, growth and fussy eating assessed by a paediatric-specialist RD.

  • Red flag: eating disorder concerns

    If signs of an eating disorder are spotted, the right step is a specialist eating-disorder pathway - not a diet plan.

Options

What each option is actually for.

  • Initial dietitian consult

    A one-hour first appointment: history, goals, and a starter plan you leave with.

  • Full assessment + bloods

    Consultation plus a targeted blood panel to find the deficiencies and patterns behind symptoms.

  • Body composition (DEXA) + review

    Fat, lean mass and bone density measured properly, then interpreted in a nutrition review.

  • Sports nutrition

    Fuelling, hydration, supplementation and body-composition strategy for training and competition.

  • Disease-specific (diabetes, CKD, IBD)

    RDs with a clinical specialism in the condition you have - not a generalist guess.

  • Weight-management programme

    A longer arc of care - plan, follow-ups and support - including GLP-1 medication support where appropriate.

  • Paediatric nutrition

    Growth, feeding, fussy eating and allergy diets, led by a paediatric-specialist RD.

  • Post-bariatric follow-up

    Structured nutritional care after gastric surgery - protein, vitamins and long-term monitoring.

Safety and practicalities

A clinical assessment, not a diet product.

Nutritional assessment is low-risk - but the wrong plan, especially in pregnancy, childhood or eating disorders, can cause real harm. The details matter.

  • Dietitian is a regulated protected title (RD)

    Only HCPC-registered dietitians can legally use the title.

  • "Nutritionist" is not always regulated

    Anyone can call themselves a nutritionist. Look for a registered dietitian (RD) or, where relevant, an ANutr/RNutr-registered nutritionist.

  • Fasting for some bloods

    Cholesterol and glucose panels usually prefer an 8–12 hour fast. Your provider should tell you exactly what applies.

  • Food-frequency questionnaire

    A validated FFQ is commonly used so the RD can see what you actually eat over weeks, not one recall.

  • Culturally-appropriate advice available

    Plans built around your kitchen, culture and family meals - not a generic template.

  • Pregnancy needs specialist RD

    Nutritional needs shift in pregnancy. Look for an RD with maternal specialism.

  • Paediatric needs specialist RD

    Children are not small adults. Growth, feeding and allergy work needs a paediatric-specialist RD.

  • Eating disorder red flags require specialist ED pathway

    If concerns are identified, a specialist eating-disorder service is the right route - dietary advice alone can be harmful.

  • Never over-supplement without RD input

    Some vitamins and minerals are harmful in excess. Correct deficiencies with a clinician, not a bundle.

Reading your report

A nutrition report can look intimidating. It isn’t.

However detailed the assessment, the write-up follows the same four parts.

A quiet reminder

Read the Impression first - the plan is the point, not the numbers.

If you would like it talked through before your follow-up, ask your dietitian or GP.

Frequently asked

Common questions about nutritional assessment.

Quick answers on cost, referrals, body composition, sports nutrition and when to see a GP first.

  • What does a dietitian actually do?

    A dietitian assesses your diet, medical history, bloods and body composition, and builds a personalised plan for a specific goal - weight, sport, a diagnosis, or family health. It is a clinical assessment, not a generic diet.

  • Dietitian vs nutritionist - what is the difference?

    Dietitian is a legally protected title, regulated by the HCPC, and only qualified clinicians can use it. "Nutritionist" is not always regulated - anyone can use the title. Registered Nutritionists (ANutr/RNutr) with the AfN are the well-regulated exception. Look for an RD or an appropriately registered nutritionist.

  • How much does a private nutritional assessment cost in London?

    An initial dietitian consultation is typically £120–£280. A full assessment with bloods runs £250–£500, and a body-composition DEXA with review £350–£700.

  • Do I need a referral?

    No. Most private dietitian appointments accept self-referral. For medically complex cases your dietitian may involve your GP or consultant so the plan fits your care.

  • What is body composition and do I need it?

    Body composition measures fat mass, lean mass and bone density - usually with DEXA. It is more useful than BMI for athletes, weight management and post-bariatric follow-up, but not everyone needs it.

  • Can you help with sports nutrition?

    Yes. Sports-specialist RDs cover fuelling, hydration, recovery, body composition and supplementation for amateur and elite athletes.

  • Do you support GLP-1 medications (Ozempic, Mounjaro, Wegovy)?

    Yes. GLP-1 medications work best alongside a proper nutritional plan - protein, micronutrients and long-term habits. RDs can support patients on these medications and after coming off them.

  • What if you think I have an eating disorder?

    If red flags for an eating disorder are identified, the right route is a specialist eating-disorder service rather than a diet plan. Dietary advice on its own can be harmful in eating disorders.

  • How long until I get results and a plan?

    You leave the initial consultation with a starter plan. A full assessment with bloods is typically written up within 5–7 days.

  • When should I see a GP urgently instead?

    Unintentional weight loss, persistent vomiting, blood in stool, severe abdominal pain, or signs of an eating-disorder crisis need a GP or A&E first - not a dietitian appointment.

In practice, in London

Why private nutritional assessment moves differently in London

With nutritional assessment, the London question is usually about report turnaround and the radiologist reading it - not whether the scan is available. The NHS route for nutritional assessment is thorough, but the queue is real. Many patients are told to expect anywhere from a handful of weeks to several months, depending on their local trust and how the referral is graded. Going private in London usually collapses that window to a matter of days - often the same week if the diary allows. It isn’t about jumping a queue so much as buying time back while you still have the flexibility to plan around it.

In practice, a private nutritional assessment appointment in London means a named consultant, a proper hour in the room (or the equivalent on a video call), and a report you can actually read. Many of London’s private clinics sit around Harley Street, Chelsea and Fulham, and turnaround on findings is often measured in days, not weeks. For nutritional assessment specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.

It helps to keep expectations realistic. A private nutritional assessment appointment in London won’t change the underlying medicine - the guidelines, the consultants, and the equipment are largely the same as on the NHS. What it changes is speed, continuity, and the amount of time you get to actually talk through the findings. UK doctors must be GMC-registered, and independent healthcare facilities in England are regulated by the CQC.
