Personalised nutritional therapy from an industry-leading specialist
You've tried to get better. You just haven't had someone look at your whole picture.
Most people who come to me have already seen their GP. They may have a diagnosis. What they don't have is resolution, and they're living with symptoms that have been managed but not investigated: bloating, exhaustion, weight that won't shift, hormonal disruption, poor sleep and brain fog.
Good nutrition advice is not complicated. Truly personalised nutrition advice, the kind that identifies root causes, not just symptoms, takes experience, rigour and time.
I'm Natalie Gillan, a registered nutritional therapist with 18 years of clinical practice and over 2,000 patients, specialising in hormonal health, gut health and weight management, including support for patients with weight loss procedures and medication. I hold a PhD and am registered with BANT and the CNHC. GPs and other practitioners refer patients to me when standard care has not delivered results. I work in London and online.
I work with each patient as an individual: taking a full health history, not just current symptoms, running targeted testing to identify root causes and providing the continuity of support that sets my clients' results apart.

With Natalie's expert help I've had the best blood sugars I've ever had in 25 years!
I've had type 1 diabetes for 25 years and have always struggled to control my blood sugars despite diabetic nurses and dietitians involved in my care. Unfortunately I now have diabetic complications including risk of blindness. With Natalie's expert help I've had the best blood sugars I've ever had in 25 years! This is amazing and will now help to prevent further deterioration. She is forensic in her research and I love that she treats the whole person not the symptoms. Superb care!!

Would I recommend the program? 500% yes. It’s the best investment in your health you’ll ever make.
I've managed to lose 3.5 stones already, I feel so much healthier and stronger - physically and emotionally. It's incredible what looking after yourself can do to your wellbeing. I've always been that person who'd plan on starting the diet on Monday and still can't believe that after my initial consultation with Natalie I felt so motivated, I simply decided to start there and then. The best part of it is that I never looked back since. Natalie has been incredibly supportive throughout the program, adjusting my supplements, suggesting new recipes, explaining how to balance my diet and even allowing me a little treat on special occasions. We started easy and then introduced a few extra steps to boost the weight loss. And it comes from someone who's always loved to eat! I still doubt my will power and stick to my program religiously, but I did have a piece of cake on my partner’s birthday this week and laughed when my weight dropped the next day. I think it was a reward for not finishing that generous piece of cake on my plate – again the unthinkable for the old me who always finished every meal. Would I recommend the program? 500% yes. It’s the best investment in your health you’ll ever make.

I am finally getting better after 10+ years and no doctor/specialist being able to trace the cause.
Natalie is my nutritionist and has been helping me with my gut health. She’s given me targeted testing so I’m not wasting money on unnecessary tests and I’ve really seen and felt amazing progress from it. Shes patient, incredibly knowledgeable, accommodating and always there to answer questions I have. I’m someone who has struggled with sleep for as long as I can remember and I can now sleep straight through until the morning, which is worth its weight in gold. I’m now not feeling the discomfort/pains after eating and I have a much better understanding of what’s causing these issues. I feel much sharper at work and am finally getting better after 10+ years with these symptoms and no doctor/specialist being able to trace the cause. I would highly recommend Natalie!
