Top Nutritionists in London

London has a wide range of private nutrition services, from HCPC-registered dietitians working with medical conditions to registered nutritionists supporting general health, behaviour change and lifestyle goals.

The distinction matters. “Dietitian” is a protected title in the UK, and anyone using it must be registered with the Health and Care Professions Council. “Nutritionist” is not a protected title, although the Association for Nutrition maintains the UK Voluntary Register of Nutritionists for practitioners who meet its standards. BANT and CNHC registration relate to nutritional therapy and should not be treated as equivalent to HCPC dietetic registration.

The seven practices below cover general nutrition, gastrointestinal dietetics, sports performance, weight management, paediatric work and functional-medicine-led services.

What distinguishes a suitable nutrition professional?

A suitable practitioner should be clear about qualifications, registration, scope of practice, fees and when medical referral is needed.

Before booking, check:

• Whether the practitioner is an HCPC-registered dietitian, AfN-registered nutritionist or nutritional therapist
• Experience with the specific condition or goal
• Whether a GP or consultant referral is needed
• What is included in the fee
• Whether follow-up support is required
• Whether tests are optional or central to the programme
• How results are interpreted
• Whether supplements are sold by the clinic
• How the practitioner coordinates with medical care
• Cancellation and refund terms

Nutrition support can complement medical care but should not replace diagnosis, prescribed medication or specialist treatment.

How much does a nutritionist or dietitian cost in London?

Private appointments commonly cost between £100 and £250, but specialist clinics and longer functional-medicine consultations can charge £300–£500 or more.

Typical cost components include:

• Initial consultation
• Follow-up appointment
• Written plan
• Meal planning
• GP or consultant letter
• Laboratory testing
• Supplement recommendations
• Body-composition assessment
• Messaging support
• Package commitment
• Cancellation charge

A higher fee does not automatically indicate stronger evidence or better clinical care. Compare qualifications, scope, appointment length and follow-up rather than price alone.

Eat Yourself to Health Clinic

Address: 16 Colfe Road, Forest Hill, London SE23 2ER
Phone: 07752 294138
Format: In-person and online consultations
Practitioner: Kirsten Brooks
Published price: Initial 90-minute consultation £189; 60-minute follow-up £105
Website

Eat Yourself to Health Clinic is an independent Forest Hill practice led by Kirsten Brooks. The service is structured around extended consultations, food-diary review and a personalised nutrition and lifestyle plan.

Brooks publishes qualifications including a nutrition degree and nutritional-medicine training and describes herself as a registered nutritionist. Clients should verify the current register and professional-body status directly where this is important to the decision.

The clinic works with concerns including energy, stress, cognitive health, digestion, hormonal symptoms and general weight management. It also offers functional laboratory testing, including stool and nutrigenomic options.

Testing can be useful where it answers a defined clinical question, but it should not be assumed necessary for every client. Ask what decision a test will change, whether it is clinically validated, who interprets it and whether a GP or specialist should be involved.

The initial fee includes time spent preparing recommendations after the appointment. Follow-up support is available individually and through packages.

Pros

• Publishes clear consultation prices
• Longer initial appointment with food-diary review
• In-person and online options
• Direct continuity with one practitioner

Best for: Clients wanting an extended independent nutrition consultation with ongoing continuity.

What to confirm: Verify current professional registration and ask which tests, supplements and follow-ups are optional.

The London Clinic of Nutrition

Address: 10 Wyndham Place, London W1H 2PU
Phone: 020 3332 0030
Format: Functional medicine and nutritional therapy clinic with online and in-person services
Published price: Initial nutritional consultation £425; 45-minute follow-up £300; 30-minute follow-up £200
Website

The London Clinic of Nutrition uses a multi-practitioner functional-medicine model for clients with complex or persistent symptoms.

Its service covers digestive complaints, fatigue, autoimmune conditions, women’s health and other symptom-led concerns. The clinic also offers laboratory testing, supplements and services including intravenous nutrient therapy.

The model is considerably more intensive and expensive than a standard dietetic appointment. The published £425 initial consultation includes a written report, dietary and lifestyle recommendations, supplement guidance and testing recommendations.

Provider claims about “root causes”, detoxification or large improvements should not be treated as guarantees. Complex fatigue, suspected Lyme disease, mast-cell symptoms, neurological change and other significant conditions require appropriate medical assessment.

Intravenous therapy carries medical risks and should be delivered only with suitable clinical governance, prescribing, infection control and emergency procedures. Clients should ask who assesses eligibility and how adverse events are managed.

Pros

• Multi-practitioner team
• Publishes consultation fees
• Online and central London access
• Broad functional-medicine and testing service

Best for: Clients who specifically want a comprehensive functional-medicine programme and understand its costs and limitations.

What to confirm: Ask which practitioner will lead the case, their registration, the evidence for each proposed test and whether medical referral is needed first.

Dietitian Fit

London address: 17 Cavendish Square, London W1G 0PH
Phone: 020 8168 6887
Format: London and online team service
Professional model: HCPC-registered dietitians
Published price: Free discovery call; initial consultation from £149; follow-ups from £54
Website

Dietitian Fit provides access to a team of HCPC-registered dietitians covering general and clinical nutrition.

The published service areas include weight management, gastrointestinal health, diabetes, paediatric nutrition, sports nutrition, women’s health, renal nutrition and disordered eating. The breadth allows clients to be matched according to clinical need rather than relying on one generalist.

A discovery call is used to identify the appropriate practitioner. It is a triage and matching stage rather than a clinical assessment, so clients should not expect a full nutrition plan before the paid consultation.

The clinic also advertises genetic and other testing. As with any commercial test, ask whether the result is clinically actionable and whether standard history, blood tests or food-pattern assessment would answer the question more directly.

People seeking help with eating disorders should confirm that the assigned dietitian works within a multidisciplinary pathway involving appropriate medical and psychological support.

Pros

• HCPC-registered dietitian team
• Broad clinical and age-group coverage
• Publishes starting consultation prices
• Online and central London options

Best for: Clients seeking regulated dietetic support across a broad range of medical and lifestyle concerns.

What to confirm: Ask for the named dietitian’s HCPC details, exact fee, appointment length and relevant specialist experience.

Raquel Britzke Nutrition Clinic

Address: 4 Wimpole Street, London W1G 9SH
Phone: 020 7123 8488
Format: In-person and online dietetic programmes
Founder: Raquel Britzke, registered dietitian
Main focus: Weight management, sports nutrition and body composition
Website

Raquel Britzke Nutrition Clinic is a dietitian-led practice focused strongly on weight management, body composition, fitness and behaviour change.

Britzke publishes HCPC dietitian status alongside sports-nutrition training and personal-training credentials. The wider team includes dietitians and nutrition professionals, so clients should confirm the credentials of the practitioner assigned to them rather than assuming every team member has the same registration.

The clinic uses body-composition analysis and offers structured programmes, consultations, testing and ongoing support. Body-composition measurements can help track trends, but readings vary with hydration, recent food, exercise and device method. They should not be treated as exact measures of health or metabolism.

DNA and exercise-related tests are also advertised. Ask how results influence recommendations and whether the proposed changes differ meaningfully from standard evidence-based dietetic advice.

Weight support should avoid guaranteed losses, moral language around food or unnecessary restriction. Clients with a history of disordered eating should disclose this before entering a weight-focused programme.

Pros

• Dietitian-led London clinic
• Strong focus on weight management and sports nutrition
• In-person and online formats
• Body-composition monitoring available

Best for: Clients wanting a structured dietitian-led programme linking nutrition, exercise and body-composition goals.

What to confirm: Ask who will provide the consultations, the total programme cost and whether testing is optional.

Lucy Kerrison / LK Nutrition

London service: Marylebone, central and south London locations, plus online appointments
Phone: 07742 086866
Office hours: Monday to Friday, 8am–5pm
Professional model: Consultant gastrointestinal dietitian with an HCPC-registered dietitian team
Website

Lucy Kerrison leads a specialist gastrointestinal dietetic practice supporting adults with persistent digestive symptoms and diagnosed gut conditions.

The service covers IBS, inflammatory bowel disease, reflux, constipation, diarrhoea, bloating, food intolerance concerns, gut–brain interaction and women’s-health-related digestive symptoms. The team’s dietetic registration is important where nutrition advice intersects with medical treatment.

Gut symptoms can have causes that require medical investigation. Unexplained weight loss, bleeding, anaemia, persistent vomiting, severe pain, fever or a major change in bowel habit should be assessed medically rather than managed only through dietary restriction.

Evidence-based elimination approaches such as a low-FODMAP diet should include structured reintroduction. Remaining on a broad restrictive diet indefinitely can reduce variety, create nutritional gaps and worsen food anxiety.

The practice works online and across London locations. The exact clinic, practitioner and fee should be confirmed during enquiry.

Pros

• Specialist gastrointestinal dietitian team
• HCPC and BDA registration is clearly stated
• Covers IBS, IBD and complex digestive presentations
• In-person and online options

Best for: Persistent gut symptoms and medically informed elimination or reintroduction work.

What to confirm: Ask whether medical investigation is needed, which dietitian will lead the case and how reintroduction will be managed.

Richard Allison Nutrition at ISEH

Clinic: Institute of Sport, Exercise and Health, London
Phone: 020 3447 2800 or 07878 661250
Practitioner: Dr Richard Allison, registered dietitian and SENr practitioner
Format: Private performance-nutrition and clinical-dietetics consultations
Website

Richard Allison Nutrition focuses on performance nutrition for athletes and active clients. Allison is a registered dietitian and appears on the Sport and Exercise Nutrition Register.

The service is relevant to competition fuelling, recovery, body composition, injury periods, travel, gastrointestinal symptoms during exercise and nutrition around training loads.

Sports nutrition should be based on the demands of the sport, schedule, medical history and current intake rather than generic supplement routines. Athletes subject to anti-doping rules should disclose this and use products with appropriate batch-testing assurance.

The clinic operates within the Institute of Sport, Exercise and Health, where multidisciplinary support may be available. Clients should clarify whether coordination with sports medicine, physiotherapy or other professionals is included or separately charged.

The service is more specialist than necessary for someone seeking basic healthy-eating advice. Its value is strongest where performance goals or clinical sports issues require detailed planning.

Pros

• Registered dietitian and SENr practitioner
• Specialist performance-nutrition focus
• Suitable for competitive and recreational athletes
• Clinic setting linked to wider sport and exercise expertise

Best for: Athletes and active clients needing performance, recovery or competition-specific nutrition.

What to confirm: Ask about the consultation fee, sport-specific experience, anti-doping safeguards and multidisciplinary charges.

The Gut Health Clinic

Address: 1 Welbeck Street, London W1G 0AR
Format: Specialist registered-dietitian team with online and London appointments
Founder: Dr Megan Rossi, registered dietitian and researcher
Published price signal: Initial consultations around £175; follow-ups around £115
Website

The Gut Health Clinic is a specialist dietitian-led service founded by Dr Megan Rossi. Its team includes registered dietitians with different areas of gastrointestinal and wider nutrition expertise.

The clinic supports IBS, inflammatory bowel disease, food intolerance concerns, women’s health, weight management and other digestive presentations. A larger team can help match clients with a practitioner whose experience fits the condition.

The service should not be confused with microbiome products, books or general media advice associated with the founder. Clinical suitability depends on the individual dietitian and care plan.

Gut testing and supplements should be considered only where they serve a clear purpose. Commercial microbiome tests do not always produce clinically useful recommendations, and broad exclusion diets should not be used without a reintroduction strategy.

The clinic is recognised by several private insurers, although authorisation and coverage depend on the policy and practitioner.

Pros

• Team of registered dietitians
• Strong gastrointestinal specialisation
• Published indicative consultation prices
• In-person, online and insurer-supported pathways may be available

Best for: Clients wanting a larger specialist team for IBS, IBD or other ongoing gut concerns.

What to confirm: Ask which dietitian will be assigned, whether insurance pre-authorisation is needed and what follow-up pathway is recommended.

Dietitian, nutritionist and nutritional therapist: what is the difference?

Dietitian

“Dietitian” is a legally protected title. Dietitians must be registered with the HCPC and are trained to assess and manage nutrition in relation to health and medical conditions.

Registered nutritionist

The title “nutritionist” is not protected. Practitioners registered with the Association for Nutrition may use designations such as RNutr or ANutr according to their status.

Registered nutritionists commonly work in public health, research, food, behaviour change, sports and individual advice. Their scope depends on training and competence.

Nutritional therapist

Nutritional therapists may register with bodies such as BANT and CNHC. Their training and model differ from dietetics. Registration should be verified, and clients should ask how the practitioner handles medical conditions, referral and evidence.

No professional title removes the need to check competence in the specific problem.

When to choose a dietitian

A dietitian is generally the clearest choice where nutrition intersects with:

• Diabetes
• Kidney disease
• Liver disease
• Inflammatory bowel disease
• Coeliac disease
• Food allergy
• Eating disorders
• Tube feeding
• Cancer treatment
• Bariatric surgery
• Paediatrics
• Malnutrition
• Complex medication
• Pregnancy complications

A GP, consultant or specialist team may need to remain involved.

Laboratory and genetic testing

Private nutrition clinics may offer stool, hormone, nutrient, genetic, food-sensitivity and metabolic tests.

Before paying, ask:

• What clinical question the test answers
• Whether the method is validated
• Whether the result changes treatment
• Whether NHS or standard private testing is more appropriate
• Who interprets the result
• Whether abnormal findings require a doctor
• Total laboratory and interpretation cost
• Data-storage arrangements

IgG food-sensitivity panels should not be treated as proof of food allergy. Suspected allergy requires appropriate medical assessment.

Supplements

A practitioner may recommend vitamins, minerals, probiotics or other products.

Ask:

• Why the supplement is needed
• Expected benefit
• Dose and duration
• Interaction with medication
• Pregnancy or breastfeeding safety
• Monitoring
• Whether the clinic receives commission
• Whether a food-based option exists

“Natural” does not mean risk-free. High doses and combinations can cause harm.

Weight management and body composition

Responsible weight support should consider health, eating behaviour, medication, sleep, activity, culture, affordability and previous dieting.

Be cautious where a provider:

• Guarantees rapid loss
• Uses extreme calorie restriction
• Sells unlicensed medication
• Treats a body-composition scan as a diagnosis
• Requires unnecessary supplements
• Dismisses disordered-eating history
• Uses shame or moral language around food

Weight-loss medication requires medical prescribing and monitoring. Nutrition professionals who are not qualified prescribers should not present themselves as independently prescribing it.

Gut health and restrictive diets

Digestive symptoms are common, but they should not automatically lead to extensive food exclusion.

A structured plan should include:

1. Medical red-flag screening
2. Symptom and diet history
3. Appropriate investigation
4. Time-limited intervention
5. Reintroduction
6. Nutritional adequacy
7. Review

Long-term unnecessary restriction can reduce fibre and variety and make eating socially difficult.

Eating disorders and disordered eating

Nutrition support for an eating disorder should usually form part of multidisciplinary care.

Ask whether the provider works with:

• GP or psychiatrist
• Psychological therapist
• Medical monitoring
• Specialist eating-disorder team
• Risk assessment
• Crisis plan

A general weight-loss programme is not appropriate where active eating-disorder symptoms are present.

Paediatric nutrition

Children may need specialist dietetic support for allergy, faltering growth, feeding difficulty, gastrointestinal disease, diabetes or restrictive eating.

Parents should confirm:

• Paediatric experience
• Growth monitoring
• Medical referral
• School coordination
• Allergy safety
• Supplement dosing
• Consent and confidentiality
• Involvement of the child’s GP or consultant

Adult nutrition advice should not simply be scaled down for a child.

Sports nutrition and anti-doping

Athletes should disclose their sport, training load, competition schedule, medical history and anti-doping obligations.

Supplements can contain undeclared or contaminated ingredients. Look for appropriate batch-testing schemes and retain product records.

Performance nutrition should support health and recovery rather than encourage dangerous dehydration, rapid weight cutting or chronic under-fuelling.

Questions to ask before booking

• What is your professional registration?
• Can I verify it independently?
• Have you worked with this condition before?
• What does the initial fee include?
• How many follow-ups are usually needed?
• Are tests optional?
• Do you sell supplements?
• Will you write to my GP?
• What symptoms require referral?
• What is the cancellation policy?
• How is my health data stored?
• Can I stop a package early?

Clear answers are more useful than broad promises about balance, detoxification or “root causes”.

Common warning signs

Be cautious if a practitioner:

• Claims to cure a medical condition through diet
• Advises stopping prescribed medication
• Guarantees weight loss or symptom resolution
• Diagnoses from a commercial test alone
• Sells every client the same supplement programme
• Discourages GP involvement
• Uses unvalidated allergy testing as a diagnosis
• Recommends prolonged restrictive diets without reintroduction
• Cannot explain professional registration
• Pressures clients into an expensive package immediately

Frequently asked questions

Is a nutritionist the same as a dietitian?

No. Dietitian is a protected and regulated title. Nutritionist is not legally protected, although AfN registration provides an important professional benchmark.

Do I need a GP referral?

Usually not for private appointments, but a referral or medical assessment may be appropriate for significant symptoms or insurance claims.

Can nutrition cure IBS?

Dietetic intervention can help many people manage IBS symptoms, but it is not a guaranteed cure and diagnosis should be medically appropriate.

Are food-intolerance tests reliable?

It depends on the test. IgG panels are not accepted as a diagnosis of food allergy. Discuss symptoms with a GP, allergist or dietitian.

Is a low-FODMAP diet permanent?

No. It is generally intended as a time-limited elimination followed by systematic reintroduction and personalisation.

Can a nutritionist prescribe medication?

Only a practitioner who separately holds the relevant prescribing qualification and professional authority can prescribe medication.

Are online consultations suitable?

They can work well where examination is not required and documents can be shared securely. Urgent or complex medical symptoms may need in-person assessment.

Will insurance cover a dietitian?

Some policies cover registered dietitians, often with referral or pre-authorisation. Check the practitioner and policy before booking.

Choosing with confidence

Eat Yourself to Health offers continuity with one registered nutrition practitioner, while the London Clinic of Nutrition provides a higher-cost functional-medicine model.

Dietitian Fit and Raquel Britzke Nutrition Clinic offer broader dietitian-led services, with Dietitian Fit spanning more clinical categories and Raquel Britzke focusing strongly on weight and performance.

Lucy Kerrison and The Gut Health Clinic provide specialist gastrointestinal dietetics, while Richard Allison Nutrition adds a clear performance and sports-nutrition route.

Choose according to professional registration, the specific condition, scope of practice, complete cost and willingness to coordinate with medical care. Useful nutrition support should make recommendations understandable and practical without promising outcomes that cannot be guaranteed.
