Nutrition & Weight Management · Harley Street
Nutrition & Weight Management Clinic in London
Dietitian-led, science-based nutrition and sustainable weight management at 19 Harley Street.
Finance available on the full cost, 0% APR up to £2,000 with Klarna (subject to status)
Good nutrition is personal. Our dietitian-led service builds a plan around your body, your history and your goals, rather than a one-size diet. The focus is sustainable change: restoring metabolic health, steady weight management, and habits that last beyond a short programme.
Every plan starts with a consultation, in person at 19 Harley Street or online. We assess your health, diet and lifestyle, then set realistic, evidence-based steps guided by current NHS and NICE recommendations.
What does a dietitian consultation involve?
We begin by understanding the full picture: your medical history, current eating patterns, activity, sleep and what you want to achieve. From there you get a personalised, practical plan with clear steps, not a generic meal sheet.
Follow-up sessions track progress and adjust the plan as your body responds, because sustainable results come from steady, realistic change rather than quick fixes.
Can you support me while I am using prescribed weight management medication?
Yes. If you have been prescribed a weight management treatment by a qualified prescriber, the right nutrition alongside it helps you get safe, lasting results: protecting muscle, managing appetite changes, and keeping your intake balanced.
This is a nutrition and dietetic service. We do not advertise, prescribe or supply weight loss medicines. Any medication is a separate matter for a qualified prescriber; our role is the dietary support around it.
Do you help with PCOS, menopause and gut health?
These are core areas of the service. Nutrition can play a real part in managing PCOS, supporting the body through menopause, and easing digestive concerns. Plans are tailored to your situation and reviewed as things change.
Longevity nutrition, support around fertility and IVF, and eating for muscle and strength are also areas we work in. If nutrition is not the right answer for something, we say so and point you in the right direction.

Working with our clinicians
Nutrition often works best alongside medical care. These GMC-registered doctors support the areas where the two overlap.
Frequently asked questions
Is this a weight loss injection service?
No. This is a dietitian-led nutrition service. We do not offer, advertise or supply weight loss medicines. We provide personalised dietary support, which can include helping people who have separately been prescribed weight management medication to eat well and get safe, lasting results.
Are consultations in person or online?
Both. You can see the dietitian in person at 19 Harley Street, London, or book an online consultation if that suits you better. The assessment and personalised plan are the same either way, and follow-up sessions can be arranged in whichever format works for you.
Will I get a personalised plan or a standard diet?
Personalised. Your plan is built around your health, preferences and goals, not a fixed template. It is practical and realistic, designed to fit your life so the changes are sustainable, and it is adjusted over follow-up sessions as your body responds.
How long until I see results?
It depends on your goals and starting point, and sustainable change is gradual rather than instant. The aim is lasting metabolic health and steady progress, not a rapid short-term drop. Your dietitian sets realistic expectations for your situation at the first consultation.
