Just wanted to email you with a big thank you for helping me to manage my eating regime. I was very pleased with my race results.





I was a relatively competitive athlete but wasn’t getting any better. My relationship with food was challenged, but Claire Fudge unzipped all of my psychological hang-ups and addressed it with science. It freed me from worrying, and I actually started enjoying food again. It’s an educational investment, a change-in-whole approach, and something I will carry through for life. I can’t recommend her highly enough.





Where I’ve really benefited from working with Claire Fudge is around the timing of food around my training, but also particularly around travel. Working with Claire on a plan so that I don’t go for chocolate in the airport or at the petrol station, but have snacks and planned timing along the way has really been beneficial. She’s great at delivering helpful tips that are quick and easy to do.





“I could start to eat intuitively again; I recovered my menstrual cycle and eat intuitively without any fear; she was there with support and guidance”





“swam my fastest 100m since I stopped competitive swimming as a kid…. I am feeling great”





When I started nutrition coaching with Claire I’ve saw an absolutely incredible difference in not only my racing performance and day to day training, but a difference in my everyday life. It has changed how I perceive food and how I think about myself and how I can best fuel myself for what I have to do that day.





I wanted to understand what food is good for me as I trained and when doing races…..some foods did not agree with me but I did not understand why……..Gave me these answers and has helped me improve my race times as well as eat more sensibly. My lifestyle has benefited from this enormously. I received expert advice on what to eat during (injury) ….incredibly helpful and informative and I was impressed at her wealth of knowledge & experience. “Claire helped me understand what foods work for my body. I’ve improved my race times and transformed my lifestyle.”





I have worked with Claire for over a year having suffered with disordered eating from an early age. I knew I needed to do something to change it.





training for my first Ironman I knew how important getting my nutrition right would be leading up to the race and on race day. Claire has helped me more than I could have imagined. Lifestyle changes we have discussed and implemented have meant that unlike any fad diets before; I am leaner and letting my food be the proper energy and recovery source it should be. Claire is always supportive, really cares about the people she works with and I love her approach to nutrition; working with what you have to make the best out of your body.





“help with a long standing issue, It was her personality, honesty and openness which gave comfort in trying her methods. Over the year that I have spent working with her, I have gained the knowledge and insight to manage my symptoms, giving me a new found sense of freedom. I would wholeheartedly recommend Claire to anyone who needs nutritional advice.”





In Claire, I have found a dietitian who not only is a specialist in nutrition, but also really understands the specific demands of an athlete. She acknowledges that one size does not fit all and really considers all the different aspects in optimizing nutrition for me as an individual. Most importantly, she helps me understand every little step of the process so that I know how to fuel myself even when she’s not around.





A friend who is a no nonsense athlete was working with Claire and I thought she would be good for me as although not a ‘real’ athlete myself, I wanted to understand how to fuel for 70.3 training and simultaneously sort out my ongoing chaotic relationship with food and eating for ‘normal life’. I knew Claire had an understanding of and worked in both areas.





I cam to see Claire in the run-up to my first ironman event. Within days of following her advice, I saw a noticeable difference; Training is improving all the time. All is on track for nailing the nitrition for the ironman event next month!





Thank you for your help over the last few months. It was very helpful and I learnt many things I was not aware of before.





“before my first 70.3 …we identified my intolerances for everyday life, (she helped) fuel my training sessions and put together a plan for the lead up to my race and race day itself. “Claire being a triathlete herself, her advice is second to none”





A big thank you for helping me to manage my eathing regime. Meal advice before the race seemed to really help keep my stomach settled on race day. I was very pleased with my race results. Really impressed by how good I feel and not so tired. A lot of this has to do with my new meal plans for training and racing.





“Your encouragement means a lot at a time when work and training is difficult and I cannot see the journey back to ‘normal’….. your positivity is highly contagious – I feel better already “





Great first meeting and assessment with Claire. A huge amount to take in but Claire guided me through the first stage. Have some clear first steps to work on in my journey to improving my hydration and nutrition to support improved training and race performances.





I really enjoyed the discussions with Claire. She gave me really good and relevant advice which helped me a lot to overcome my problem.





I started working with Claire when I realised that I thought I knew what I was doing but I really didn’t when it came to sports nutrition. I’d been competing at an age group level internationally in triathlon and since working together, my performances have improved together with making podium places as well as making the jump up to 70.3 a successful one.





Just wanted to email you with a big thank you for helping me to manage my eating regime. I was very pleased with my race results.





Claire challenged my unhealthy food beliefs in an empathic manner and suggested changes that were specific and achievable whilst continuing in my recovery from anorexia. “her knowledge and support have been really valuable in the progress I have made over the past few months and I would definitely seek her advice in the future.





I’ve learned so much stuff I didn’t even know existed, different types of proteins, when to take, when to take dairy, how to stay full, what’s a good probiotic to boost my immune system…I’m always learning, I think I’ve really improved” . –





“exceptionally supportive …excellent knowledge of nutrition both in terms of supporting sports performance but also in optimising health. Claire’s background in long distance triathlon herself means that she is able to support in ways others wouldn’t …..her race and training experiences. I (would) recommend Claire for anyone who is looking for support with their nutrition – either for optimising everyday health and wellness or for enhancing and supporting sports performance”





“ frankly i hadn’t got any knowledge….Claire was amazing! She helped me plan out my nutrition… to make sure i was getting the best performance (this) allowed me to fully concentrate on the competition.. “best competitive season of my life so far, gaining my first GB senior vest competing at the Athletics World Cup, 2nd place at the British Championships and becoming England Champion gaining my first England Senior International vest”





I’ve been running for quite a few years, but I just kept running out of energy. Training for a marathon, I got in touch with Claire. I thought she would just give me a food plan, but she basically educated me on what I needed to eat and the right food groups to eat together. It was just an absolute game changer. I did my marathon with absolutely no problems—didn’t once run out of energy.





“I thought I needed a diet plan; but that is exactly what I didn’t need. I gained the knowledge and support and the balancing of everyday life around training along with personal life too”.





“I run better, I feel better, I’m not getting injured, and I sleep well”. “I thought I needed a diet plan; but that is exactly what I didn’t need. I gained the knowledge and support and the balancing of everyday life around training along with personal life too”.





Struggling with allergies, intolerenaces and anxiety around food for many years had a huge umpact in my daily life, being able to properly fuel for marathon training, recovery and race days. Symptoms have improved dramatically, my training is much more efficient and my confiedence around food has grown. I have lost count of the different diets and plans that I have tried; I have seen a really positive change. I really couldn’t recommend Claire any more highly.

I had a sweat test done by Claire – I’ve yet to put the results into practice, but really enjoyed our discussion. She explained the process and how to put the results into practice very clearly. She also seemed to me to have a very balanced view (it was not just a sales pitch for Precision Hydration!) which gave me a lot of confidence in her advice.





Since working with Claire, she’s made a huge difference to the way that I’ve been able to execute my training sessions, bring the energy that I need at the right times to competition, and get the most out of recovery. I wholly recommend giving Claire a call. The biggest thing to take away is that everything that we do is absolutely manageable!





“helped me relearn that “Food is food”.Fed up of seeing zero results through yo-yo dieting, I had tried intermittent fasting, Keto and various other diets. I wanted a lifestyle change and wanted to be able to enjoy food without the guilt associated with “bad food”. I can now enjoy eating fruit without feeling guilty! I’m confident I will reach my goal weight comfortably and remain constant”





“Claire’s methods didn’t leave me feeling hungry or depleted of energy like fad diets can, in fact I couldn’t quite understand how I was able to eat quite so much and feel so full and strong………what a difference having a nutrition plan to work with made. My performance rocketed and I completed my two dreams in one season. Medalling at the European Middle Distance AG triathlon and smashing my first ironman”





“ Claire went into a lot of detail, preparing nutrition plans for me and for ½ and full races and also assisted me with recovery nutrition. She is very supportive and knowledgeable. I would highly recommend her”
Frequently Asked Questions
The right service depends on whether you are looking for support as a driven professional, a professional who competes, an athlete, a team, a research organisation or an event organiser.
If you are unsure where to begin, book a discovery call and we will guide you towards the most appropriate pathway.
No. I work with professional and Olympic-level athletes, athletes on talent and high-performance pathways, competitive age-group athletes and professionals who train, race or compete alongside demanding careers.
The level at which you compete is less important than your commitment to improving your health, fuelling and performance.
I also support driven professionals who are not athletes but want to improve their energy, focus, resilience and long-term health.
Personal Performance Precision is my approach to creating nutrition support that is fit for purpose and designed around the individual.
Generic plans are built for an average person. They do not account for your physiology, health history, symptoms, training, workload, lifestyle, preferences or goals.
Personal Performance Precision brings these factors together with clinical expertise, performance science and meaningful personal data. This allows us to identify what is affecting your health and performance, then engineer a practical strategy around your specific needs.
Like a tailored suit rather than something taken straight from the rack, the strategy is shaped around you: how you live, how you move, what your body needs and what you are working towards.
The result is not simply more nutrition information. It is a clear, personalised approach designed to support your energy, health, recovery and performance now and over the longer term.
In the UK, dietitian is a legally protected title. Dietitians are regulated healthcare professionals qualified to assess and treat nutritional problems, including those associated with medical conditions.
The titles nutritionist and nutritional therapist are not legally protected, so qualifications, training and experience can vary. Registered Nutritionists and nutritional therapists who belong to recognised professional bodies may have completed relevant training, but their scope of practice differs from that of a registered dietitian.
As a Registered Clinical Dietitian and High-Performance Nutritionist, I combine clinical assessment and evidence-based care with specialist sports and performance nutrition.
This is particularly important where symptoms, blood markers, low energy availability, gut issues, injury, REDs, disordered eating or a medical condition may be affecting health and performance.
Yes. I provide specialist clinical and performance nutrition support for athletes and active individuals with eating disorders, disordered eating, Relative Energy Deficiency in Sport (REDs) and low energy availability.
Support may include nutritional rehabilitation, restoring adequate fuelling, reducing nutrition-related risk, supporting training and recovery, and working alongside doctors, psychologists, physiotherapists, coaches and other members of the multidisciplinary team where appropriate.
Where clinical risk is present, the priority is always safe, coordinated and appropriate care.
A clear plan for what, when and how you eat can be valuable, but lasting change requires more than a prescriptive meal plan.
Where appropriate, I provide personalised meal structures, fuelling plans, practical food ideas, competition strategies and guidance around timing, recovery and preparation.
These sit within a wider approach that considers your health, schedule, training, travel, preferences, symptoms and goals.
The aim is to give you a strategy you can understand, adapt and sustain rather than a rigid plan that only works temporarily.
Most individual support is delivered through a structured programme rather than a single appointment.
A first consultation begins the process of understanding your symptoms, patterns, data, health history, training demands and goals. Follow-up support allows recommendations to be implemented, reviewed and refined.
One-off specialist consultations may be available for clearly defined needs, such as an expert review or sweat sodium testing.
Please contact the team to discuss the most appropriate option.
You will be guided towards the service that best matches your goals, health needs and performance demands.
Where appropriate, the first step will be a discovery call or initial conversation to understand the support you are looking for and whether the service is the right fit.
You will then receive clear information about the recommended pathway, what is included, the expected timescale and the investment required.
A limited number of new clients are accepted each month to maintain the depth and quality of personalised support.
