Registered Dietitian in London (Harley Street)

Looking for a registered dietitian in London? Raquel Britzke is an HCPC-registered dietitian (DT28960) with over 18 years of clinical experience, based at 33 Cavendish Square, Marylebone, London W1G 0PW — in the Harley Street medical area. She leads a team of registered dietitians and nutritionists offering evidence-based, personalised nutrition care in person and online.

Whether you need a dietitian in London for weight loss, PCOS, menopause, IBS, GLP-1 (Mounjaro/Wegovy) support, pregnancy, sports performance or a specific medical condition, the clinic sees patients from across Central London, Westminster, Kensington & Chelsea, Camden, Islington, the City of London and beyond — and online from anywhere in the UK.

Dietitian or nutritionist — what is the difference in the UK?

“Dietitian” is a protected title. Only practitioners registered with the Health and Care Professions Council (HCPC) can use it, and only dietitians are trained and regulated to treat medical conditions with diet. “Nutritionist” is not a legally protected title in the UK. Raquel is both an HCPC-registered dietitian and a registered nutritionist, so you get clinical expertise and a practical, whole-person approach in one place.

What our London dietitians help with

• Weight loss — structured 1:1 programmes with real food, no fad diets
• PCOS — insulin resistance, cycles, fertility and weight
• Menopause and perimenopause — weight, hot flushes, sleep and energy
• IBS and gut health (low FODMAP) — elimination, reintroduction and long-term plan
• GLP-1 nutrition support — protecting muscle and building habits on Mounjaro, Wegovy or Ozempic
• Type 2 diabetes and prediabetes — remission-focused nutrition
• Pregnancy, fertility and child nutrition
• Sports nutrition — performance, muscle gain and body composition
• Food intolerance and allergy testing and DNA-based nutrition
