ExcellentDietitian Fit - Nutritionist & Dietitians5.0 Based on 120 reviews fromSee all reviews review us onMary Isabel Vieira de R.Mary Isabel Vieira de R. ★★★★★ I want to express my sincere gratitude to Dr. Marlene Ferreira for her exceptional care and professionalism. Her knowledge and dedication have been fundamental in our health improvement process. Thanks to her advice and nutritional plans, she has helped us manage the situation. I highly recommend Dr. Marlene to anyone seeking an expert and committed nutritionist. Thank you so much for everything, doctor!Julia S.Julia S. ★★★★★ I worked with Reema for 6 months and she was a breath of fresh air compared the judgmental nutritionist I'd seen prior. She changed my entire way of eating and my approach toward food. Her kind, empathetic, and helpful way of working was so appreciated.When I first saw Reema, I was working through reclaiming my body after an IVF miscarriage. By changing my eating habits, I was able to conceive naturally and I'm now in the second trimester of my pregnancy. She honestly changed my family's life for the better and I could not be more grateful.Anastasia L.Anastasia L. ★★★★★ I, once again, decided to lose weight not only because I wanted to become fitter but also to avoid becoming a diabetic. My blood tests showed that I was in a pre diabetic stage and losing weight would be very important.I decided this time to ask for professional help from a dietitian rather than embarking on one of the commonly used diets and this is how I met Katerina Ageridou in Dietitian Fit.Katerina understood from our first consultation that I needed to change a few habits that would act as a deterrent in loosing the weight and gave me several tips on how to achieve this change! She also gave me dietary advice to achieve both losing the weight and to avoid diabetes. She demonstrated that she can pair her extensive knowledge on nutrition with the individual needs of her clients helping them to achieve their goal!I found Katerina’s help during our consultations invaluable because her advice for a start motivated me to start the journey of losing weight but it will also help in the long run to reach my target weight and to maintain it. Hopefully this effort will also result in avoiding diabetes.Katerina I can’t thank you enough !Rebecca S.Rebecca S. ★★★★★ I have struggled with my weight for many years, and finding Isabella has truly been life-changing. Her knowledge, support, and personalized approach have made all the difference. In just the first few months, I have lost almost 12 kg, and I know this is just the beginning of my journey. Each session with Isabella is an opportunity to learn and grow, and I am constantly amazed by how much I have gained from her expertise. I couldn't recommend her more highly and only wish I had met her sooner. Thank you, Isabella, for helping me on my journey to better health!Andrew M.Andrew M. ★★★★★ IoannisIoannis ★★★★★ Working with Isabella had been fantastic. Even though I was aware of the basics, her knowledge and advice helped me gain a better understanding of what I need to do on a daily basis.

Isabella was always available to answer my questions and provide support along the way.Highly recommended!Danielle G.Danielle G. ★★★★★ What a lovely lady with so much knowledge ! I’m so excited to be working with her. She made me feel so at ease in the phone and that I can help my child’s sting habits… music to mother’s ears!

Her manner was calm, friendly and informative and she was very knowledgeable. She made the experience enjoyable and collaborative and I really enjoyed our sessions.Katie SKatie S ★★★★★ I had a really great experience with Kat and saw consistent weight loss each week after having hit a plateau in my own efforts to lose weight. Kat was really supportive throughout, and explained how to make conscious food choices which didn't make it feel like I was dieting, even when eating out at restaurants etc. She was really great at explaining how I can eat well and nourish my body without having to give up any foods that I love and how to reframe and combat emotional eating which was a big problem for me in the past. I couldn't recommend her more!Zoe P.Zoe P. ★★★★★ Fantastic dietician so helpful and friendly. Alicia was great she really listened to me and to my neuro divergent child.

Kat was brilliant to work with, she is encouraging, empathetic, non-judgemental and insightful. I felt like I was working with someone who truly cared about my journey. Although, I didn't reach my goal weight, I now have the tools, guidance and mindset to get there and feel much more confident about managing a sustainable healthy lifestyle that works for me.Christine H.Christine H. ★★★★★ From stephen Harvey:My experience was very rewarding , diet plans tailored to my needs .Katerina was very knowledgable and informative about my personal issues.Explaining all the pros and cons of my eating habits, and dietary needs.By following the plans prepared for me and exercising i shed 23KG., it was hard going at first , but with on the ongoing support , i perseveredi’m very thankful for my results :My motto is“Never give up” you can’t put a price on your health .P MP M ★★★★★ I had a great experience with Anastasia Gkegka.

I wholeheartedly recommend Dietitian Fit & Co for anyone on the path to a healthier, happier lifeThank you, Kat,Katy S.Katy S. ★★★★★ My sessions with Susan have been hugely beneficial in resetting my mindset around food and nutrition. I had got sucked into diet culture through social media, and was also heavily influenced by my upbringing and diet culture of the 90s and 00s. Susan has a kind, caring, but no nonsense approach which was refreshing. I have become more mindful of what I’m eating from a holistic nutritional sense rather than purely focusing on calorie content, which I am so pleased about.Hind el M.Hind el M. ★★★★★ Very caring and helpful for my IBSThank you AnastasiaNaomi C.Naomi C. ★★★★★ I signed up for the 6 months course and have had such an amazing experience. Kat has been so wonderful and the process was really well structured. I feel like I'm now equipped with the knowledge to make better decisions around food and can eat what makes me happy.It does take time but it's so worth it and I totally recommend to anyone.Thanks Kat!Maria Luisa S.Maria Luisa S. ★★★★★ Kat is honestly amazing and wonderful ! My situation was a bit difficult because I was trying to gain weight while continuing my intense training schedule. Kat completely understood me and she suggested me a meal plan so that I could gain weight and fuel my training properly. Thanks to her, I have now gained 4kg and I have improved my sport performance. I could have not done it without her😊 plus she has always been very available . I can’t recommend her enough !!Hannah B.Hannah B. ★★★★★ So, I've been struggling to try and put into words just how much Anastasia has helped me and I really dont think I can do it justice. Food has never really been my friend and I remember having eating issues back when I was 17. Over the years these problems developed and become an all encompassing dread pretty much from the second I woke up to when I went to bed. I couldn't eat anything outside of "my plan" , I had to weigh EVERYTHING (including how much coffee I put in my cup so it would then match the nutritional info on the tin), I couldnt eat out, whether spontaneous or not, I would be constantly hungry and could not remember what it felt like to be full....on the other hand, when I couldnt control my willpower I would break. I would eat and eat and eat until I was sick. I am now 38 years old. I have tried self help, psychologists, counsellors, hypnotherapists, doctors, personal trainers with their nutrition guidelines, meditation and whatever else you can think of with no positive effect. I then met Anastasia thinking I at least needed someone to tell me it was ok to eat more....but, without realising it, I found someone who gave me so much more. She listened to me. Every suggestion she gave was tailored to me and it wasnt just about what food to eat, it was to help my mental state as well. I didnt feel like I was just another case to her, she really knew me and she really cared. I couldnt remember how to eat properly, couldnt see a light at the end of the tunnel. I'd been struggling for so long that I couldnt see me ever getting better and yet with the support and guidance she's offered me I haven't used the scales for nearly a month. I've managed to identify feelings of hunger, which I'd lost the ability of a long time ago. I've relaxed over my different meals and am able to give myself more variety, adapt on a day to day basis and go out for dinner without it sending me into a ball of anxiety, resulting in me eating SO much the day before the meal - due to the stress and panic - that I was then too ill the next day to go. Anastasia has given me my life back. I can breathe again. I relax more when food is in front of me, I can go out with my friends and it doesn't take up every thought in my mind. I still have lots of work to do but Anastasia has given me the confidence in myself to now see a future where I can eat well and still love myself. I can see that I actually may make it and I cannot thank her enough. This still hasn't explained things well enough. I wish I could so she understood how she has changed my whole world when I couldnt and how grateful I really am.Emma D.Emma D. ★★★★★ I signed up for 6 months dietician support to help me lose 10kg in weight. Kat was excellent and provided me with a lot of useful information to help me achieve my goal and slowly but surely I have continued to lose weight over this time. The support was tailored to fit in with my normal lifestyle and eating habits so it is easy to continue the new meal plan layouts without feeling I am having to adapt greatly or miss out on anything. I have eaten out, travelled and thoroughly enjoyed my time whilst losing the weight and feel much better for it. I would highly recommend considering Dietician Fit as Kat has built up my knowledge and confidence, always on my side, my own personal cheering section without any judgement. Thank you Kat and Dietician Fit.Hannah L.Hannah L. ★★★★★ Katerina has helped me lose 6kg in the space of 5 months which is something I have tried to do for years! Katerina gives you a diet plan which is varied but focuses on nutrition rather than on the diet. I would highly recommend Katerina as she has a good balance of being firm with compassion and education. The education will stay with me for life. Thank you Kat xxIvana B.Ivana B. ★★★★★ I have been working with Marlene on my fitness goals, namely body recomp and better recovery after training sessions. Marlene is extremely knowledgeable, compassionate and was very mindful of my mindset in this process. She has guided me in my sports diet journey creating sustainable meal plans that include all the food I enjoy and aid in muscle recovery and growth. I have reached my maintenance levels, and depending on my next fitness goals, I am sure I will be working with Marlene again! Thank youLiberty F.Liberty F. ★★★★★ Kat was incredibly helpful in my food journey, unravelling years of being labelled a fussy eater as well as using diet to help manage my adhd, feel good in my body and just enjoy food. She listened to my needs, making helpful suggestions, guiding me with resources and strengthening my relationship with food as a result. I am now able to enjoy foods that I love the taste of, and foods that make my body feel great, honouring my cravings without binging. She has taught me how to include the nourishment I need without compromising the enjoyment of a meal.Katy T.Katy T. ★★★★★ I have been working with Anastasia on the 3 month programme and it’s going super well.Anastasia is super knowledgeable and has helped me work towards my weight loss goals. From Anastasia I now understand what a healthy balanced diet looks like which has allowed me to lose weight and gain energy and feel healthier overall. Would highly recommend!Saira A.Saira A. ★★★★★ 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.alissa S.alissa S. ★★★★★ Working with Kat has been a pleasure from start to finish!Since working with her I have been on a few holidays, never said no to a night out or a restaurant meal (within reason), however I have consistently seen results as she has managed to tailor a plan around my lifestyle rather than forcing massive unrealistic changes. I would definitely recommend her, and I will very likely do some extra session myself here and there just to keep me accountable!Lloyd B.Lloyd B. ★★★★★ Kat was just what I needed. So warm, great energy and a fountain of knowledge. Listened to what I wanted and was able to adapt my nutrition to my lifestyle. I now have the knowledge I need to succeed in a better nutritional dietJelena S.Jelena S. ★★★★★ It's a great programme and I really enjoyed working with Kat on changes to my lifestyle! She is very knowledgeable but also compassionate and is totally dedicated to getting to know the factors that have impact on my wellbeing, adjusting my plan so that it suits me perfectly and I feel great physically and notice my gradual weight loss and even my thinking's changed! I'm now much more mindful about what I eat and drink and how I organise my day just by making a few simple changes, and the results are incredible and already noticeable by others! Thank you Kat:)Chiara P.Chiara P. ★★★★★ Susan N. was very approachable, knowledgeable, holistic, and encouraging with my dietary needs and goals. I learned ways of gaining weight more quickly and had a better understanding of what was behind my difficulty putting weight on. Her recipes look delicious and it was especially helpful to understand how portions work.She was generally a very kind, down to earth, and warm practitioner to work with and I was happy to see her for my sessions.Although I didn't reach my desired weight, I acknowledge that this was due to stressful circumstances and I was at one point able to gain more than I had in quite a while, which was an achievement in and of itself. I am hopeful that I have now been given the tools to reach my desired weight in due time.Many thanks Susan for your understanding and help!Terry H.Terry H. ★★★★★ The service they give is first class got me on the right track to my weight loss and information on how to maintain it as well and guidance on weekly meetings many thanks to Marlene for her help and supportHelen L.Helen L. ★★★★★ Katerina has been so supportive, encouraging and has changed my mindset with food .

She is an extremely competent professional who accompanied me in my weight loss journey, incorporating elements of emotional eating and lifestyle changes.
