ExcellentDietitian Fit - Nutritionist & Dietitians5.0 Based on 220 reviews fromSee all reviews review us onKarineKarine ★★★★★ I had a fantastic experience with my dietitian. I initially reached out for support with my gut health, but the advice went far beyond just managing my digestive symptoms. My dietitian took the time to understand my overall health, lifestyle and goals, and created a personalised plan that was realistic and easy to follow.Since working together, my digestion has improved significantly, I have much more energy, and I feel like I have a far better understanding of how to eat to optimise my overall health and wellbeing.The advice was evidence-based, practical and tailored specifically to me rather than being a generic diet plan. I would highly recommend Dietitian Fit to anyone looking for a knowledgeable gut health dietitian or wanting to improve and optimise their overall health.Magda S.Magda S. ★★★★★ Tenishia WTenishia W ★★☆☆☆ [March 2025] Personally, I think I misunderstood what this service would entail. However, my first dietician (Karine Patel) and the manager I spoke were truly a lovely bunch of humans.My second dietician (Isabella Alfonso) who I switched too for weight loss and protein support didn’t review the meal photos I would submit in the app, nor were they discussed in our sessions, and she would just ask how my week had been. It didn’t feel helpful or the deep dive that I was looking for. It felt very driven by me, and it felt like there was a lack of curiosity on her part. I felt like a box to be checked. At £597 I had expected something more or different - it just didn’t feel worth £299 a month. I didn’t see or feel the value, personally.They did check in on my experience, and I said I would give Isabella the feedback. I didn’t because I was uncomfortable. Sounds silly, but I felt like she didn’t particularly like me. After recently reflecting on the cost and my experience, I did opt for a review for the benefit of others considering this service.I would recommend a dietician if you have a chronic health condition because the support likely would be a lot clearer.Anne A.Anne A. ★★★★★ Sarika worked with me. My goal was to get to 78-79 kg. As a woman in menopause, my weight was increasing despite the fact that I was physically active. I couldn’t understand why. I got in touch with Diet Fit and I’m glad I did so. I got tailored support and I lost just over 5kg within 3 months. Even if I didn’t meet my target by the time I completed 3 months, I made very good progress and I have continued working to achieve my ideal weight. Sarika gave me the advice and tools, but ultimately, the hard work was on me. I highly recommend DietFit. Thank you,Sarika.Maria A.Maria A. ★★★★★ Working with Kat Ageridou has genuinely transformed my relationship with food, and I can’t recommend her highly enough.I first started seeing her after my ACL surgery because I wanted to lose weight in a healthy, sustainable way while retaining muscle and making sure I was properly nourishing my body. What I didn’t expect was how much she would completely change the way I think about food.Before working with Kat, I lived with so many unnecessary food rules. I constantly labelled foods as “good” or “bad”, restricted myself, and felt anxious around eating. Even something as simple as having pasta would make me feel stressed because I thought I couldn’t eat a normal portion. I also avoided keeping sweets at home because I was convinced I shouldn’t have them around.Now, I have a completely different relationship with food. I can have chocolate, biscuits and other treats in my kitchen and enjoy them whenever I want as part of a balanced lifestyle. Food no longer has power over me, and I no longer feel guilty or anxious about eating.Kat taught me what balanced meals actually look like and helped me understand that no food needs to be demonised. Rather than putting me on another restrictive diet, she gave me the knowledge and confidence to build habits that I know will carry me through life. It’s not about dieting, it’s about changing your lifestyle and building a healthy, sustainable relationship with food.What makes Kat truly exceptional is not only her expertise but also the way she makes you feel. From the very first session, I felt completely at ease. She creates such a warm, supportive and judgement-free space that you can be completely honest without ever feeling embarrassed or criticised. She listens with genuine care, understands that life isn’t perfect, and always meets you where you are.Her knowledge is incredible, but it’s also so practical. She always had ideas for balanced meals, healthy snacks, sweet treats and delicious recipes that never felt restrictive. When my life became particularly challenging, whether because of work, my recovery or simply not having the energy to cook, she adapted everything to my circumstances instead of expecting me to fit into a rigid plan. She recommended nutritious ready meals, easy meal ideas and realistic alternatives that meant I could still look after myself, even during difficult periods. That flexibility made all the difference.The impact has gone far beyond nutrition. My social life feels so much freer because I don’t spend time worrying about meals or feeling anxious when eating with other people. I feel healthier, more confident and so much more at peace with food than I ever have before.Perhaps the biggest testament to Kat’s work is that I no longer need her. I’ve now maintained my weight for over a year, and I feel confident navigating food on my own. I know how to build balanced meals, I know how to adapt when life gets busy, and I trust myself around food. She didn’t just help me lose weight, she gave me the tools, the mindset and the confidence to look after myself for the long term.To me, that’s the mark of an exceptional dietitian. The goal isn’t to keep clients dependent forever, it’s to empower them to eventually not need you. Kat has done exactly that, and I will always be grateful for the lasting impact she’s had on my health and my lifeBea WBea W ★★★★★ Working with Kat over the last six months has been one of the best decisions I've made for my health. She has a wonderful way of cutting through all the noise around nutrition and focusing on what actually works for the person sitting in front of her.Kat never tried to squeeze me into a one size fits all plan. Instead, she listened, adapted, and helped me find practical solutions that fitted my lifestyle, even when life inevitably got in the way. Her advice was sensible, realistic, and refreshingly free of guilt or fads..What I appreciated most was that Kat didn't just help me lose weight she helped me change the way I think about food and build habits that feel sustainable. The weight loss has been a fantastic result, but finding a healthier balance that I can actually maintain feels like the bigger win.Kat is knowledgeable, encouraging, and just the right amount of delightfully unconventional. She has a knack for making the process feel achievable rather than overwhelming, and her genuine enthusiasm for helping people is impossible to miss.If you're looking for someone who combines expertise with empathy, common sense, and a refreshingly human approach, I couldn't recommend Kat more highly.Thank you Kat! 🙂Selin C.Selin C. ★★★★★ Working with Kat has completely changed my relationship with food. I really appreciated her holistic approach and how she looked at the bigger picture instead of just focusing on weight.She helped me understand that healthy eating doesn't mean cutting out foods you enjoy. Instead, she taught me what it actually looks like to nourish my body and build habits that are realistic and sustainable. Thanks to her, I learned that I could enjoy food, enjoy life, and still make progress towards my weight loss goals.Kat was kind, supportive, and explained everything in a way that was easy to understand. I'm so grateful for everything she's taught me. Thank you, Kat!Buchi E.Buchi E. ★★★★★ I’ve been working with Isabella for a few months and honestly the progress has been solid. As a boxing athlete with a decent training load, dietary restrictions, and a West African background where oil-heavy cooking is just how food is made at home - I wasn’t sure how well a nutrition plan would actually fit my life. She took the time to understand how I train, what I eat, and where I come from, then worked around all of it.Her patience and persistence stood out. No generic advice. She built something that actually made sense for me.ThanksFred B.Fred B. ★☆☆☆☆ Not as expected, basically told how many calories I needed and macros, along with a generic meal plan. I could have AI’d the data I got. Nothing tailored around my individual exercises. Very money orientated, not even finished my intro session and I was being sold further packages to give ‘ongoing support’. Waste of £149JermelJermel ★★★★★ I always read reviews against businesses and it’s the reviews which had been left against Isabella that made me choose her.A game plan was put together and actioned with zero time wasted. We completely stripped my diet back to basics and then slowly re built it back up to align with my body and goals.I highly recommend Isabella for sure.Thank you.Felicy B.Felicy B. ★★★★★ I saw Georgina, after my colleague at work recommended me to her for weight loss and cholesterol management, and I have had a very positive experience. She created a practical, personalized nutrition plan tailored to my lifestyle, food preferences, and health goals, which made it much easier to follow consistently.One of the things I appreciated most was the clear guidance she provided on which foods to include in my diet and which foods to limit or avoid. She also supplied helpful charts, meal guidelines, and easy-to-follow resources that made tracking my progress and sticking to the plan much simpler.I have already seen improvements in my overall health, and I feel much more informed about making healthier food choices. She is very knowledgeable, supportive, and professional, always taking the time to answer questions and provide encouragement. I would highly recommend her to anyone looking for personalized dietary advice and sustainable lifestyle changes. Thank you Georgina! FelicyGillGill ★★★★★ Highly recommendedMatilda H.Matilda H. ★★★★★ Chandni P.Chandni P. ★★★★★ Kat was exactly what I needed to help me understand where I was going wrong with my eating habits, especially while dealing with health issues. She made things simple and clear—helping me become more aware of what I was eating, stay consistent, and follow the plan she created for me.I’m so grateful for the genuine care and support she showed throughout all of our calls. By following her guidance, I’ve already lost 2kg, and I’m continuing this journey towards making it a long-term lifestyle change.Thank you so much, Kat!Chris K.Chris K. ★★★★★ I used Dietician Fit over a few months with the Dietitian Isabella. She helped with meal planning and support. I was able to gain muscle and loose weight while learning about nutrition. Everything covered was done in a supportive, sensible and friendly way. I was left with the ability and knowledge to increase or decrease, start and stop where required and feel confident about continuing the process on my own. It very much feels like I found the missing part of my health I was looking for. I would obviously recommend Dietician Fit and Isabella specificallyDaniel RDaniel R ★★★★★ I’d been wanting to change my diet for a long time and enrolled with Katerina at Dietician Fit for the three month programme.I found Katerina and her programme to be brilliant. Katerina is immensely knowledgeable, realistic and motivational. She introduced me to a new way of thinking about food, new ingredients and I never went hungry.My objectives are now achieved - a transformed and sustainable diet and obvious health benefits. Full marks to Katerina.Suzanne C.Suzanne C. ★★★★★ Kat was great professional friendly and gave me a lot of information and guidance to help an support me. Thanks Kat.Jack S.Jack S. ★★★★★ Isabella has been a great help tailoring dietary choices and improving the quality of food I eat.MaxMax ★★★★★ As a young guy, it can be a little bit daunting to approach someone and admit that you’ve effectively struggled with your weight for your entire life and none of your diets have worked.In meeting and continuing to work with Georgina Broinowski I have not only experienced the longest ‘health kick’ of my life (to the point where it’s beginning to become the norm), but I have become more educated on what healthy eating looks like for men.Her holistic, rounded approach is unmatched. The process felt almost like psychoanalysis with the care taken to understand why my eating habits exist, and how to reasonably and sustainably improve them. I am happy to have lost weight, but even happier to be actually content in myself.The feeling of my body thanking me for the activity and nutrition I now provide it with is like no other. I want to exercise, I love (and am more consistently getting) a good sleep and meals are still tasty (I smoke my own salmon and have worked in kitchens. Safe to say food tasting good will always be at the top of my agenda. Georgina has shown me that this and health are not mutually exclusive!).I would recommend this service to anyone looking to simply be healthier. Regardless of your level of fitness or perceived health already. Thank you!!MaxVince C.Vince C. ★★★★★ I was skeptical at the beginning, but the results proved me wrong. I can’t recommend Kat enough. She says her approach is science-based, but in reality she brings a lot of human touch to it as well.ethereal A.ethereal A. ★★★★★ Georgie has been amazing! After years of dealing with IBS and endometriosis symptoms, and a recent SIBO diagnosis, I really needed help figuring out my diet. From the start, Georgie has been so attentive and understanding of my needs. She’s incredibly knowledgeable and always there to answer questions or support me along the way. I’d 100% recommend her if you’re looking for a dietitian!Samira M.Samira M. ★★★★★ I started working with Georgina at the end of January, and in such a short period of time my gut health has improved immensely, particularly my digestion and bowel movements. The difference in how I feel day-to-day has been incredible.Georgina is incredibly caring, attentive, and very clear in her communication. She takes the time to really listen and understand my needs, which makes the whole process feel supportive and personalised.What I appreciate most is how practical and simple her guidance is. The small steps and changes she recommended have genuinely transformed my daily habits and overall wellbeing.Georgina also specialises in a wide range of areas, but so far we’ve been focusing on the areas I’ve personally been struggling with, and the progress has been amazing.I’m now continuing to work with Georgina alongside my gastroenterologist to improve my lifestyle further and build confidence in my body and in the foods I eat.I’m really grateful for her support and would highly recommend her to anyone looking for compassionate and knowledgeable nutritional guidance.Thank you Georgie!Suzanna R.Suzanna R. ★★★★★ Kat was extremely supportive in my journey to change my relationship with food. The resources were helpful and I had added health benefits I didn't expect. I would highly recommend having a course with Dietitian Fit for long term health benefits.Lizzie M.Lizzie M. ★★★★★ I can’t recommend Isabella enough. Working with her while training for my first marathon completely changed my relationship with food. She gave me a straightforward, realistic plan that actually fit into my life, while making sure I was properly fuelled for training and race day. I felt stronger, more confident, and far less stressed about what I should be eating. If you’re looking for a dietitian who truly listens and supports you, she’s amazing.Eileen D.Eileen D. ★★★★★ I started to work with Georgina mid-November 25, and I am still under her care. Her approach is entirely holistic, and she has gone above and beyond to support me, in every way, through a very difficult time. She has provided excellent medical advice, not only in relation to nutrition but has also acted as an advocate with my GP, communicating regularly with the surgery on my behalf to ensure that my clinical needs are being met. As time has gone on, I have been more able to take an active part in decisions about my treatment and Georgina has again been fantastic in her response, listening, supporting and advising at every stage. I cannot recommend Georgina too highly and can only say a heartfelt thank you for all the care and much needed moral support so far received.Lucy J.Lucy J. ★★★★★ Kat was brilliant throughout our sessions. She was very encouraging and taught me a lot about how to structure meals in a flexible and nutritious way. She gave me lots of tips of how to manage social occasions where I can’t control portion sizes or what food I’m served.I feel a lot more in control of my food choices than I ever have before, I have more energy, I’ve lost weight, and I feel more satisfied with my meals.Thank you so much Kat!Elena S.Elena S. ★★★★★ I first came here 5 years ago, and returning has been one of the best decisions I’ve made. Over the past three months working with Kat I felt completely supported, reassured, and genuinely cared for. She has such a warm, understanding approach that made everything feel achievable.I’ve rebuilt a healthy, happy relationship with food -I can manage my weight, cravings, enjoy eating and feel calm and in control again. Everything now fits naturally into my routine. It’s been freeing, uplifting, and truly joyful 😊I’m incredibly grateful to Kat for this journey ♥️Saira A.Saira A. ★★★★★ Updated review 2025:I had several sessions with Megan in early 2025, and she was truly a blessing during that time. She is the second dietitian I’ve worked with at Dietitian Fit, and my appreciation for the team has only grown stronger.Megan works with exceptional integrity and a kindness that is genuinely rare. It’s clear that her priority is truly helping people. She is a real asset to the field of nutrition and leaves a lasting impression through her professionalism and compassion.She supported me through my challenges with a very personal approach, was always available to contact, and consistently made an effort to respond with care and attention.Old review 2023:I had a few sessions with Anastasia for nutritional support. She is incredibly authentic, genuinely passionate and knowledgable and exceeded any expectations.I would highly recommend Anastasia for anyone looking for nutritional support, she has all the skills and knowledge to make sure the science is correct whilst simultaneously being able to explain and relate on a personal level with any struggles.She creates a safe space and with her help I do believe you will achieve your end goals and have a highly successful chance of flourishing.Karen P.Karen P. ★★★★★ I worked with Kat over a 6 month time frame and I learnt so much about my eating habits and how to balance out a busy life and work schedule with my eating which helped so much. I hope to continue with my progress and to do some follow up sessions in the new year, total worth it to have that moral support. Thank you so much Kat.Charlotte J.Charlotte J. ★★★★★ I just completed the 3-month programme with Kat and I feel like my relationship with food has changed forever in the best way possible. I started off really scared and sceptical, but stuck to her plan and within a couple of weeks I started feeling better, more energised and comfortable with the plan. My body has also changed a lot within three months and I'm looking great, but honestly it is how I now think about food that I am most pleased with. I can have my favourite foods, I can honour my cravings, and I can enjoy cooking, all whilst also looking after myself. This is life changing and it is something I am so grateful to Kat for.Annelies S.Annelies S. ★★★★★ I enrolled on a 3 months programme to lose weight. Georgina was my dietician, and was incredibly helpful to my efforts. She was supportive, attentive and offered solutions for any problems I encountered. She would encourage me to stick with the diet when I felt disheartened about my (at times) slow progress and assured me I was, doing well. It was a pleasure to meet her and spend time with her. She became my friend. I found the diet easy to stick with for the long term. All foods were natural, I can buy everything at a super market. I was encouraged to exercise, go for walks etc. After around 3 1/2 months I have lost a good 6 kg- so I'm nearly at a stone of weightloss. I am so thankful.AnnelieseDenise DDenise D ★★★★★ I was very skeptical when I started this journey. I have been to so many nutritionists in my life that I lost count, and to think that this would be different and I would stick with it was just silly. I am so glad I was so wrong. Kat has been the most incredible support anyone could ask for, and definitely what I have always needed. The way she listens with empathy and always comes up with a plan and a solution is seriously incredible. I have just completed six months with her and my relationship with food is finally changing - after 30+ years of trying without succeeding, this is more than I could have asked for. I am so glad I decided to stick with Kat and eager to see where the next months will take me. Thank you Kat 🙂MariaMaria ★★★★★ I just finished a 3 months plan with Katerina and I would definitely recommend. Katerina is very kind and understanding and very knowledgeable. She created a plan that can easily align with my lifestyle and requirements. I learnt a lot from our chats and I achieved the goals I set out to achieve when we started!Olivia Ruby E.Olivia Ruby E. ★★★★★ I had Kat for 3 months and I achieved all my goals and beyond what I ever expected, even having high hopes. I’ve never looked better or felt happier. The results were really night and day. Such a kind person and always looked forward to meeting with her. Best decision I’ve made. Thank you!AniaAnia ★★★★★ Katerina was so lovely and supportive throughout my six months with her. Her plan was easy to follow and really worked for me — I even lost another kilo afterwards just by keeping up with her advice! I really appreciated her real-life, practical tips that made everything feel achievable. So grateful for her kindness and encouragement!Chara S.Chara S. ★★★★★ I highly recommend Dietitian Fit. It has been life changing for me. It wasn't just about healthy weight goals. Katerina Ageridou has helped me change my habits, find ways to make it work with whatever life throws at you and have a healthier attitude towards food. From nutrition and structure to taking time to enjoy a meal, it has been an incredible and invaluable process.T D.T D. ★★★★☆ My energy improved a lot. I was having issues with it, especially after lifting weights in the gym. I would come home with no energy. and I wasn’t having enough food to sustain me after all those works outs. but I got help with that, and also got help with eating the right foods for my high cholesterol cause I didn’t know the right foods to eat to lower it. I feel more comfortable after gym, with the foods Iam eating and I’ve also seen good results with my physic.Lara Mae S.Lara Mae S. ★★★★★ Alicia has been an amazing and definitely will recommend her to families that needs assistance in terms of their baby’s dietary needs! She gave us guidelines to follow for baby weaning, gave us some ideas on how to introduce allergens as we had some initial struggles with our baby. Thank you for your help Alicia! Wish you all the best!ViolaViola ★★★★★ I’m so grateful I found Dietician Fit online. I’ve been working with Kat for around six months and it has been life-changing!After being diagnosed with a chronic inflammatory skin condition earlier this year, I knew I needed professional support to improve my diet.Kat has been amazing! Knowledgeable, kind, and supportive.She’s helped me completely transform my eating habits, taught me so much I didn’t know before, and made healthy eating achievable and sustainable. Thanks to her guidance, not only I have improved my relationship with food, but my skin condition has also improved.I honestly couldn’t recommend Kat enough—thank you so much for your help! xSerena S.Serena S. ★★★★★ I’ve just finished the 6 months plan with Kat, and I honestly don’t even know where to begin in thanking her. These past months have been truly life changing. Kat helped me transform my relationship with food, but most importantly, she gave me the tools to connect with and understand my emotions in a way I never thought possible.She has been a constant source of support, always patient, kind, and understanding. With her, I felt safe to open up freely without ever feeling wrong or judged. Every conversation with her made me feel lighter, stronger, and more confident in myself.I’m so grateful for everything she has done for me this journey with her has been one of the best investments I could have made in myself.CJ TCJ T ★★★★★ My teen daughter came to Alicia du Preez as she had been struggling with weight gain and was feeling down and unhappy with herself. She could not seem to be able to stop the putting on weight. Alicia really helped to develop healthier eating habits and motivated her to start taking better care of herself . 3 months in and 8 kgs less, my daughter is more confined in herself and - above all - in her ability to make better choices going forward.Alicia is a great communicator and really managed to instill these healthier principles into my teen. I would recommend her to anyoneD T.D T. ★★★★★ I was introduced to Dietician Fit through the NHS WebSite whilst looking for guidance in managing my weight in response to healthcare issues.Having struggled over the years to effectively and consistently manage my weight it has been refreshing to work with Isabella at Dietician Fit.Rather than being told what to do I feel I have been re-educated in how to look at food, my eating and drinking patterns, and understanding my needs. As a result of the changes I have made I have managed to lose 9% of my body weight over 3 months or so.For me the most important thing has been to have the support of somebody who has a pragmatic approach to dietary re-education. Having been somewhat sceptical as to what could be achieved at the outset, I now would not hesitate in recommending this company, and should the need arise have no qualms in reaching out to Isabella againKay S.Kay S. ★★★★★ I would like to thank Marizaan for her boundless compassion, insight and enthusiasm when working towards following an intuitive approach to eating. We worked extensively on reframing mindset around eating and in particular Marizaan emphasised the kindness and respect in the process which I valued hugely.Lucia B.Lucia B. ★★★★★ I did a 3 months program with Kat and loved it. She really helped me understand HOW to eat better in a sustainable way. I'm less hungry, I have less cravings, and in general I fell much better about my nutrition. Would highly recommendDavid A.David A. ★★★★★ I was keen to find a dietician to try & better understand what I should eat and chanced upon Ms Isabella Alfonso who has been great. Isabella was able explain what I need to eat as well as explain as to why such food is needed and in terms that I was able to understand. Additionally, Isabella was super available to respond to my various queries not only about my dietary needs but also the nutrition in general. I can highly recommend Ms Isabella Alfonso if you want to understand nutrition & your dietary needs.Jennifer M.Jennifer M. ★★★★★ Working with Kat has been the single best decision of my adult life. She has fundamentally changed the way I view food and taught me skills I will use for the rest of my life. I couldn’t recommend her more for anyone who wants to make improvements to their relationship with food, health, etc.Warren W.Warren W. ★★★★★ At the beginning of this year, I started losing some of the gains that I had been making steadily throughout 2024. In fact, my muscle mass was fluctuating quite a bit. On the advice of my PT, I decided to consult a dietician. I started working with Isabella and Dietitian Fit at the start of April. Since then, I have managed to gain 3kg in muscle mass and only 400g in fat. I’ve been incredibly impressed by the results I’ve been able to achieve in 3 short months with Isabella’s help. With the gains in muscle mass I have made, I also feel more confident to keep increasing the weights I am lifting. Thank you so much Isabella!Emily F.Emily F. ★★★★★ I couldn't recommend Reema and Dietician Fit highly enough. I found my six months with Reema helped me to change my relationship with food and understand what little changes can go a long way. I found working with Dietician Fit worth every penny and it has felt like a life-changing experience. Thank you, Reema!Florence B.Florence B. ★★★★★ Highly highly recommend! I have had guidance from Dietitian Fit in both 2020 and recently in 2025 with Anastasia and Katerina respectively. Both have been so amazing and so supportive 🙏 never felt judged and helped me uncover things about my eating habits that I didn't even realise myself. Highly recommended them, super knowledgeable and absolutely worth it.Joseph P.Joseph P. ★★★★★ I joined Dietitian Fit after training for years without really seeing the results I wanted. I wasn’t sure what to expect initially but the process was straightforward and once I was assigned Isabella Alfonso I knew I was in good hands. Professional, understanding and extremely knowledgeable! A few tweaks and I was starting to notice a difference. Now 3 months in and the results are tangible, I honestly feel the best I’ve felt mentally and physically and can’t recommend her highly enough. I just wish I’d done it years ago!js_loader

What is IBS?

Irritable bowel syndrome (IBS), also known as irritable colon, is a very common gastrointestinal disorder that affects 1 in 7 people. It affects the digestive system, where the symptoms occur mainly in the large intestine. Food intolerances are often associated with IBS.

Causes of IBS

The exact cause of IBS is not known. There are, however, numerous factors that seem likely to play a role in its development. These include:

Common Symptoms of IBS:

Stomach pain or cramps

Stomach pain or cramps are usually worse after eating and can get worse as the day goes by.

Bowel Changes

This can be constipation, diarrhea or alternating between constipation and diarrhea, meaning erratic and unpredictable and bowel habits

Bloating

Abdominal bloating - the sensation of an inflated balloon in the abdomen, your tummy feel uncomfortably full and swollen

Excessive wind/gas/ fart

Excessive flatulence where passage of flatus/gas/wind is greater then usual.

Fatigue

IBS may cause fatigue

IBS Dietitian Consultation – Our 3‑Step Process

Step 1

In‑Depth Assessment

Your IBS dietitian consultation begins with a comprehensive assessment of your symptoms, lifestyle, medical history and diet. This helps us understand your unique gut profile and identify possible triggers.

Step 2

Personalised Nutrition Plan

Based on your assessment, your dietitian will create a tailored plan which may include low FODMAP guidance, microbiome-supporting strategies, symptom tracking, dietary adjustments and supplement recommendations where appropriate.

Step 3

Ongoing Support & Review

IBS symptoms can fluctuate, which is why ongoing support is essential. Your dietitian will monitor your progress, help you reintroduce foods safely, adjust your plan and guide you through long-term symptom management.

Gut Microbiome & Weight Loss – Dietitian Support

Your gut microbiome plays a key role in appetite regulation, metabolism, energy balance and inflammation — all of which can influence weight. Our gut microbiome weight loss dietitian team helps you optimise digestive health in a way that supports sustainable weight management.

We focus on improving microbiome diversity through fibre-rich, plant-forward eating, personalised nutrition strategies, targeted probiotics when appropriate and balanced lifestyle changes. This approach helps improve digestive comfort while supporting healthy, long-term weight outcomes.

IBS dietitian

What is the best diet for IBS management/ relief?

There are many different dietary strategies that can help relieve IBS symptoms. Research at Monash University, King’s College, London and numerous other centres around the world has shown that a low FODMAP diet improves IBS symptoms in at least 75% of IBS sufferers. Therefore, a low FODMAP diet is the first treatment choice for people suffering from IBS.

FODMAP DIET

The FODMAP diet is considered one of the best and most effective IBS treatments.

What does FODMAP mean?
  • Fermentable gut bacteria ferment undigested carbohydrate to produce gases
  • Oligosaccharides – Fructans & GOS – found in foods such as wheat, rye, onions, garlic and legumes/pulses.
  • Disaccharides – Lactose – found in dairy products like milk, soft cheeses and yogurts.
  • Monosaccharides – Fructose – found in honey, apples, high fructose corn syrups, etc.
  • And
  • Polyols – Sorbitol and Mannitol – Found in some fruit and vegetables and used as artificial sweeteners.
Put simply, FODMAPs are a collection of short-chain carbohydrates (sugars) that aren’t absorbed properly in the gut, which can trigger symptoms in people with IBS. FODMAPs are found naturally in many foods and food additives.

3-step process to manage your IBS symptoms and feel at your absolute best With an ibs nutritionist!

Trust the FODMAP nutritionists at Dietitian Fit to help you obtain relief from symptoms of your Irritable Bowel Syndrome. All treatments are grounded firmly in nutritional and dietary science and do not require the use of potentially problematic pharmaceuticals.

Step 1: Low FODMAP Diet

Week 1-2: Remove all high FODMAP food to get rid of 80-90% of the symptoms.

Step 2: FODMAP Reintroduction

Week 3-8: FODMAP rich foods are reintroduced foods back into your diet one by one (total of 6 food groups) to identify which FODMAP types trigger your IBS symptoms, and which do not.

Step 3: FODMAP Personalization

After identifying your high FODMAP trigger foods, foods that are well-tolerated are reintroduced back into your diet.

In most cases, you will be able to reintroduce many high FODMAP foods back into your diet, but you may not be able to eat them in the same quantity as before.

Your IBS dietitian may also recommend you specific probiotics to increase your gut health and improve tolerance to some foods.

Frequently Asked Questions

What does a gut health dietitian do?

A gut health dietitian specialises in assessing digestive symptoms, identifying triggers, supporting the gut microbiome, and creating personalised plans to reduce bloating, cramping and irregular bowel habits.

Should I see a dietitian or a nutritionist for IBS?

Registered dietitians (RDs) are clinically trained and regulated. We are best placed to provide evidence‑based IBS care, including low FODMAP guidance.

What happens during an IBS dietitian consultation?

Your dietitian will assess symptoms, diet, lifestyle and medical history, identify potential triggers, and create a tailored IBS and gut health plan with step‑by‑step support.

Can a gut health nutritionist help with weight loss?

Yes. Improving microbiome diversity, fibre intake, digestion and inflammation can support healthy, sustainable weight loss.

Do I need to follow a low FODMAP diet?

Not everyone with IBS needs a low FODMAP diet. Your dietitian will determine whether it is appropriate for your symptoms.

Can I do the low FODMAP diet on my own?

It is not recommended. The low FODMAP diet is complex and meant to be temporary. A dietitian ensures it is done safely and effectively.

How many sessions will I need to improve my IBS?

Most people see improvements within 1-2 weeks, depending on symptom severity and response to dietary changes.

Can you help if I’ve tried everything and still have IBS symptoms?

Yes. Many clients seek support after years of symptoms. We take a personalised, root‑cause approach targeting triggers, microbiome imbalances, fibre diversity and stress.

Do you offer IBS dietitian consultations online?

Yes. We support clients UK‑wide with online IBS and gut health consultations.

Are your dietitians registered?

Yes. All our gut health dietitians are HCPC‑registered and trained in IBS, FODMAPs and microbiome‑focused nutrition.

How do I know if my symptoms are IBS?

Common IBS symptoms include bloating, abdominal pain, constipation, diarrhoea and irregular bowel habits. We can help you understand your symptoms and next steps.

Can you help with food intolerances and sensitivities?

Yes. We assess whether symptoms relate to lactose, non‑coeliac gluten sensitivity, FODMAPs, fibre types or other triggers.

Do you work with severe or complex IBS cases?

Yes. We support mixed‑type IBS, post‑infectious IBS, gut–brain axis disorders, long‑term bloating and complex digestive health conditions.
