ExcellentDietitian Fit - Nutritionist & Dietitians5.0 Based on 139 reviews fromSee all reviews review us onMarella C.Marella C. ★★★★★ Only good things to say !I have worked with Katarina, who's provided me with an easy-to-follow meal plan and various useful tips that really made the difference. Since I started my journey with her I not only feel much better physically, but I have managed to get control of my health and nutrition in the daily routine. She has always been super supportive and available, which allowed me to open up and share a lot with her.Most importantly, Katatina has greatly helped me overcoming my fears of 'trigger' foods, teaching me that no food should be eliminated as long as you are aware of what you are eating to properly nourish your body. Eating out with friends and enjoying weekends drinks has become much easier now!I highly recommend her for your weight loss/health journey 🙂Jennifer R.Jennifer R. ★★★★★ Working with Isabella has been a pleasure. She’s warm, creative and caring and has come up with some fabulous suggestions for meal prepping and organising my time to make sure work days are still good nutrition days. She can take the credit for my return to swimming, pilates and the gym too. With her encouragement and expertise I feel I’m on the path to better health.Ben H.Ben H. ★★★★★ Isabella Alfonso gave wonderful advice and made a great program that was easy to follow.SarahSarah ★★★★★ It has been a lovely experience working with Alicia and so happy to have her with us on our journey. She is very caring and went the extra mile for our toddler which we are so grateful to her for.MartaMarta ★★★★★ I cannot express how grateful I am to have worked with Kat. She is incredibly kind, sweet, and always brings a positive, sunny energy to every session. I came to her in a bad cycle of emotional eating, having gained weight and feeling completely out of control. Although I had a general understanding of nutrition, I simply couldn’t break the cycle on my own. Kat created an effective plan tailored to my needs, and more importantly, she supported me every step of the way, helping me let go of guilt and manage difficult moments.Her approach gave me a new, healthier relationship with food, and I found myself actually looking forward to our sessions, even when I felt shy or guilty about what I had logged in the app. Kat made me feel appreciated and always uplifted my spirits, no matter what. Thanks to her, I’ve reached my goal of losing nearly 5 kg, but even more importantly, I now feel in control of my eating habits. I can’t recommend her enough—Kat is truly the best. Thank you so much, Kat!Ellen M.Ellen M. ★★★★★ I did a programme with Katerina and was so grateful for all her advice and tips! She gave me achievable goals and I use the plan she made me daily. Thank you!Jade B.Jade B. ★★★★★ Alicia was amazing! She was so helpful and understanding. She really helped me understand what our little one needed to deal with his potential allergies and how to approach weening. We have a clear plan moving forward and I will definitely be reaching out again when we are ready to take the next steps!Fabrizio S.Fabrizio S. ★★★★★ I highly recommend Kat as a dietitian. Under her guidance, I successfully lost weight in a few weeks, even while being on holidays. Kat provided tailored, evidence-based advice that was practical and easy to incorporate into my daily routine. Her expertise, combined with her supportive and encouraging approach, made a significant difference in my journey. Kat also taught me to find joy in preparing healthy and balanced meals, transforming my approach to food into something positive and enjoyable. She was always available to answer my questions and offer guidance, ensuring that I stayed motivated and on track. I am truly grateful for her invaluable support and professional insight, which made this process both manageable and rewarding.Elizabeth H.Elizabeth H. ★★★★★ Susan has helped me reset my attitude to food and weight loss. By going back to the basic principles of healthy nutrition and allowing myself to enjoy food, I have been steered away from obsessing about calories and weight loss. I’ve stopped bingeing and shifted my feast or famine mentality to eating what I like without feeling guilty. It’s no longer about fast weight loss for me (followed by faster weight increase) - just healthy habits that I can sustain for life. Susan is so knowledgeable, supportive and passionate about nutrition - she makes it easy for you to change your eating habits!Terence C.Terence C. ★★★★★ An incredible person, really listens to you and provides you with so much information. Consistently checking in, willing to adapt to small things that I required, and such a positive mindset when it comes to dieting and nutrition. Would highly recommend to anyone who is looking to start out their diet journey. ⭐️Lisa T.Lisa T. ★★★★★ Marlene was realistic and set realistic goals. Her clear explanations helped me to manage cravings and understand what I needed to change.jasmine P.jasmine P. ★★★★★ As everyone in the boxing circle is aware, a boxers weight class is a common topic.A couple of years ago I made the decision to move up to the 63kg weight division.I felt fatigued and was injury prone in the 60kg division and almost swore to myself I'd never go back to that weight.However, a few months ago I decided to give it another try.Personally, i wanted to approach it differently this time with a gradual weight decrease starting a few months out to avoid the way I ended up feeling the last time I fought at 60kg.With the Help of Dietician fit and specifically Isabella Alfonso the journey back to 60kg was safe and much less stressful!I have felt fuelled during my intense training weeks and competing. And most importantly to me have felt much happier.Isabella has reassured me during this journey, especially when the human body surprises you (which as a female, it does)!And has been very adaptable to suit my needs. She asks regularly how I feel during training sessions and generally, to ensure I am as comfortable as possible.I won't vow to stay at 60kg forever, but I know whatever weight category I/my body choses, I will be well fuelled and healthy!Claudia B.Claudia B. ★★★★★ I enjoyed my journey with Kat so much! Her advice about intuitive eating was extremely helpful and I have learnt a lot about what my body needs. She is so knowledgable and she has given me a lot of tips that I've managed to implement in my daily life. So happy to have found her and would recommend her highly!Gili B.Gili B. ★★★★★ Kat played an important role in helping me establish a healthier lifestyle during a challenging time when I was moving countries and had no routine. Despite the obstacles, Kat guided me on what to eat, even when I wasn’t cooking at home. Her practical advice and unwavering support made a real difference, and I’m truly grateful for her expertise.Holly G.Holly G. ★★★★★ Katerina helped me so much with my weight gaining journey. I started with very little knowledge of dietary needs and cooking skills, yet Kat made every effort to understand how and where she needed to help me. Her emotional support and attentiveness was incredible, and I will always appreciate the safe space she created for me.Camila R.Camila R. ★★★★★ I consulted Isabella about how to modify my diet to perform in sports. She was very thorough, asked many questions regarding lifestyle and training (times and frequency, intensity, type of training, etc). She designed a meal plan without drastically changing what I usually eat, which made it easy to follow and sustainable. I'm really happy with her assessment and would recommend her to anyone looking to support a better performance in sports with diet. I have noticed I'm no longer lightheaded when lifting heavy weights or after lengthy sessions of rowing in the river. Isabella is also the loveliest person 🙂Amina N.Amina N. ★★☆☆☆ ben S.ben S. ★★★★★ Alicia was so friendly and helpful with our son’s dietary issues, producing a detailed report for us which gave lots of useful insight. Would definitely recommend!Anastasia K.Anastasia K. ★★★★★ I had a brief initial consultation with Karine who introduced me to Maia Lockhart. I then had a meeting with her which I was initially nervous about but it soon turned into a lovely experience. Maia made the effort to record all of my symptoms (PCOS) regarding my cycles, ask me about my lifestyle (work, exercise, stress, sleep), the supplements I take, and my diet overall. She provided me with a lot of information on why her suggestions could be helpful which helped reassure me that I am on the right path. I have been given a flexible meal plan, focussing on variety rather than restriction. There was no requirement to track calories which can be stressful and time consuming. I have also been given a guide towards managing my stress, and advice on how to manage my busy lifestyle. I am extremely satisfied with the amount of support I have received from a single online consultation, and I thoroughly recommend Maia as she was very friendly, compassionate and professional at the same time.Mary 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. She took the time to understand my goals and gave me a personalised plan that I could apply to my training. 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! XJona00Jona00 ★★★★★ Our experience with my daughter's dietician was exceptional. The dietician was knowledgeable, professional, and caring. She took the time to listen to our concerns and tailored a dietary plan that was suitable for my daughter.I highly recommend this dietician to anyone looking to make positive changes to their diet and lifestyle.Marta P.Marta P. ★★★★★ I can highly recommend Kat. She is very knowledgeable, paces very well the information she passes on without overwhelming you. She is clear and efficient yet also motivating, non-judgemental and truly cares about adapting the plans individually. Thanks, Kat!michael U.michael U. ★★★★★ I had the pleasure of working with Anastasia Gkegka, and I can confidently say she exceeded all my expectations. From the outset, her expertise and knowledge were evident, but it was her personalized approach that truly set her apart. Despite my initial skepticism, Anastasia's guidance and support completely transformed my perspective. Her tailored strategies not only helped me achieve my goals but also empowered me with the knowledge and tools to maintain a healthy lifestyle long-term. I highly recommend Anastasia to anyone seeking professional dietary guidance.Beatrice R.Beatrice R. ★★★★★ Alicia was extremely helpful in advising me about the diet of my ten year old autistic son. 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.

I am incredibly grateful for investing in a nutritionist as I worked through some lifestyle changes that I had to make for my overall health!Melissa A.Melissa A. ★★★★★ I worked with Kat for around 6 months and can truly say that the experience has transformed my attitude to food and dieting. I came into this looking to find a sustainable way to eat healthily and lose weight, that wasn't based on counting calories or restricting myself. I've more than achieved that with Kat. 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.
