London Clinic

Meet your nutritionist in our London clinic of nutrition at Harley Street area. If you choose an in-person visit to our London clinic of nutrition, you'll benefit from our on-site testing services. Our clinic features the latest medical-grade body composition bioimpedance technology. This technology is precise in measuring body fat, muscle mass, visceral fat, water content, and more. We pair this precise analysis with specialised services, including DNA tests and food intolerance assessments. Our expert dietitians conduct these essential evaluations. This makes our London clinic a top choice for those seeking a dietitian near me for weight loss. These advanced diagnostics provide deep insights into your physical health. They form the cornerstone of a personalised nutrition plan designed to meet your weight loss and health goals.

Arriving by car, taxi or Uber

Harley Street runs straight into the north side of Cavendish Square, so if you are already in the medical district you are a few minutes away by car and less than ten on foot. The clinic is on the south side of the square, on the parade with Pret A Manger and Starbucks, opposite the gardens behind John Lewis. Ask your driver to approach from Margaret Street or Wigmore Street rather than Oxford Street, which is closed to private traffic between 7am and 7pm Monday to Saturday. For an Uber or a private driver, 33 Cavendish Square, London W1G 0PW drops you on the right side of the square — avoid pinning John Lewis Oxford Street.

The clinic is inside the Congestion Charge zone, currently £18 a day between 7am and 6pm on weekdays and midday to 6pm at weekends. The nearest car park is Q-Park Harley Street on Queen Anne Mews, open 24 hours and four minutes’ walk; the car park that used to sit under Cavendish Square Gardens has closed permanently. On-street bays are pay-by-app until 6.30pm Monday to Saturday and free on Sundays, and there is a 24-hour black cab rank at John Lewis.

Home visits across London

For clients who would rather not travel, we also consult at home anywhere in London. It is the option most people choose after surgery, with a new baby, with limited mobility, or when the diary will not allow a round trip into W1 — and a first consultation in your own kitchen tells us more than any food diary. Ask about your postcode when you book.

Food Intolerance Test

If you experience symptoms such as bloating, digestive discomfort, migraines, or skin concerns, identifying potential dietary triggers can be helpful. However, symptoms can have many causes, and identifying food sensitivities requires careful assessment.

Food Sensitivity Assessment — How We Approach It

At our clinic, we use food sensitivity testing as one part of a comprehensive nutritional assessment. Our approach includes:

1. Detailed Assessment

  • ✦ Thorough dietary history
  • ✦ Symptom tracking over time
  • ✦ Medical history review
  • ✦ Lifestyle factors

2. Optional Testing

  • ✦ Food sensitivity testing (IgG) may be recommended
  • ✦ Testing measures food exposure (IgG antibodies)
  • ✦ Results require professional interpretation
  • ✦ Never used in isolation

3. Personalised Strategy

  • ✦ Targeted dietary trials (based on your symptoms)
  • ✦ NOT blanket elimination diets
  • ✦ Nutritional adequacy monitoring
  • ✦ Planned reintroduction of foods

4. Ongoing Support

  • ✦ Regular monitoring and reassessment
  • ✦ Adjustment based on your response
  • ✦ Prevention of unnecessary dietary restriction
  • ✦ Support for sustainable changes

⚠ Important Disclaimers

  • Food sensitivity testing is used as part of a broader clinical evaluation, not as a standalone diagnostic tool
  • We do NOT recommend unnecessary elimination diets based on test results
  • Any dietary modification is monitored to ensure nutritional adequacy
  • Reintroduction of foods is encouraged to prevent restrictive eating patterns
  • This approach follows current evidence-based guidelines from NICE, the British Dietetic Association, and the British Society of Gastroenterology

Frequently Asked Questions

Q: Is IgG food testing a diagnostic test?

No. IgG testing measures exposure to foods (presence of IgG antibodies), not food intolerance or allergy. Testing is used as part of a comprehensive clinical assessment alongside a detailed dietary history, symptom tracking, and clinical evaluation by a registered dietitian.

Q: How are food sensitivity tests used in your clinic?

If recommended, food sensitivity testing is always combined with thorough clinical assessment, monitoring of symptoms over time, individual dietary trial (not blanket elimination), nutritional adequacy checking, and planned reintroduction of foods.

Q: Will I have to eliminate foods identified in my test?

No. Our approach uses test results as one piece of information. We do NOT recommend blanket elimination diets. Instead, we monitor your specific symptom response, encourage gradual reintroduction of foods, ensure your diet remains nutritionally adequate, and help you identify your personal tolerance levels.

Q: How is this different from other testing providers?

Key differences: Always combined with clinical assessment ✓  |  Registered dietitian evaluation ✓  |  Monitoring for nutritional adequacy ✓  |  Planned reintroduction (not elimination) ✓

Q: What if I have a true food allergy?

True food allergies (IgE-mediated) require specialist evaluation by an allergist or immunologist. We do NOT diagnose or treat allergies. If you suspect a food allergy, see your GP or allergist immediately — allergies can be life-threatening. We can support nutritional management once an allergy is confirmed by a specialist.
