GLP-1 Dietitian in London

No. We are dietitians, not prescribers. We do not prescribe, supply, recommend or adjust any weight-loss medication, and we will not comment on your dose — that belongs to the doctor or clinic managing your prescription. What we do is everything on the nutrition side, and we are happy to work alongside your prescriber.

No, and this is when most people come to us. Starting mid-treatment is useful precisely because you already know how the medication affects your appetite and your gut, so the plan can be built around what is actually happening rather than what might happen. If you are approaching maintenance, it is close to the most valuable moment to get this right.

There is no single GLP-1 diet, and anyone selling you one has not met you. The principles are consistent though: hit a protein target at every meal, keep fibre and fluid up, eat little and often rather than one large meal, favour softer textures when nausea is bad, and treat alcohol carefully. What that looks like on your plate depends on your weight, your muscle mass, your dose and what you actually like eating — which is what the consultation is for.

More than you are probably eating, and spread across the day rather than loaded into dinner. We set the target from your body composition rather than a generic number, then work out how to reach it when your appetite is a fraction of what it was — usually a mix of meal structure, food choices and, where needed, protein-dense options that do not feel like a chore.

Some lean tissue loss happens with any weight loss. The published trials of semaglutide report a wide range, from almost none up to around 40% of the total weight lost. The range is that wide partly because of what people eat and whether they do any resistance training. That is the part you can control, and it is exactly what we work on — measured on the Tanita body-composition scale so you can see whether the plan is working rather than hope it is.

A great deal, and mostly through food. Smaller and more frequent meals, cooler and blander foods when nausea peaks, separating fluids from meals, getting fibre up gradually with enough water alongside, easing off high-fat and fried foods, and timing meals around your injection day. If symptoms are severe or persistent, that is a conversation for your prescriber, and we will tell you so.

Not inevitably, but the data is a warning worth taking seriously: in the STEP 1 trial extension, people who stopped semaglutide regained roughly two-thirds of their lost weight within a year. What changes that is having a maintenance plan built before you stop, enough muscle preserved on the way down, and eating habits that survive the return of appetite. We plan the exit from the first consultation, not the last.

Yes. Diabetes nutrition is core dietetic work and several of our patients are on GLP-1 medication for blood glucose rather than weight. We also run a dedicated diabetes programme — the quiz will point you to whichever fits.

Our nutrition support works the same way regardless of which treatment your doctor has prescribed. We would add one caution: we only work alongside medication that has been legitimately prescribed for you and is licensed for use in the UK. We cannot support the use of products bought without a prescription, and we would strongly encourage you not to.

It matters. “Nutritionist” is not a protected title in the UK; “dietitian” is. Our team are HCPC-registered dietitians, which means regulated clinical training and the ability to work safely with people on medication and with medical conditions. You can verify any of us on the HCPC register.

Both work. The online programme is identical in content and is what most of our UK-wide and international patients choose. The London clinic at 33 Cavendish Square adds in-person consultations and body-composition analysis at every visit.

Some policies cover dietetic input, particularly where there is a diagnosed condition. We can provide an invoice with the relevant details for you to claim — check with your insurer first, as cover varies.
