Meet our Kidney Disease Dietitian

Registered Dietitian, BSc, MSc

Chronic Kidney Disease & Kidney Health Specialist

Reema Pillai

I am Reema Pillai, a Registered Dietitian and member of the Health & Care Professions Council (HCPC) & the British Dietetic Association (BDA).

I hold a Bachelor of Science in Nutrition & Dietetics from the University of Surrey, and a Master of Nutritional Science from Loughborough University. Through my experience as a renal dietitian, I have worked with clients to improve their dietary and lifestyle habits, to maintain or even see improvements in their kidney function. It is important to consider any other health conditions such as type 2 diabetes or high blood pressure and how these negatively impact kidney health. Therefore, consultations and support will combine all possible health issues and risk factors, where I can tailor recommendations and provide structured meal guidance personalised to your condition, goals and food preferences. If you would like support with your overall kidney health, get in touch.

Area of specialties

  • Chronic kidney disease (CKD)
  • IgA nephropathy
  • Diabetes type 2 
  • High blood pressure
  • Weight loss

Why is it important to see a kidney dietitian?

Renal dietitian play a critical role in the management of chronic kidney disease (CKD). Our expertise in designing tailored meal plans that meet your unique nutritional needs for CKD  is essential to help you live healthy, and delay the progression of the disease.

Is my diet important to help me manage Chronic Kidney Disease (CKD)? 

Making the right dietary changes may help you manage your condition better and can help slow the progression of the disease. The internet is full of blogs and information that talk about foods you need to avoid to keep your kidneys healthy, however, this can be really confusing. Luckily you don’t have to figure all of this out by yourself! 

Your renal dietitian can help you with meal planning and look at your blood results to ensure your diet is right. She will help you with:
  • Choosing and preparing foods with less salt or sodium
  • Adjusting your potassium intake by advising you on the right foods to eat
  • Eating the right amount and the right type of protein
  • Consuming the right amount of fluid.
Here are some tips for developing a healthy, kidney-friendly meal plan:
  • Limit sodium: High sodium intake can lead to high blood pressure and worsen kidney function. We will help you limit your intake of processed foods and to use herbs and spices to flavour your meals instead of salt.
  • Watch protein intake: While protein is essential for good health, too much can be harmful to the kidneys. We will work with you  to determine the right amount of protein for your individual needs and to choose high-quality protein sources.
  • Monitor phosphorus: Excess phosphorus can lead to bone disease and other complications in CKD patients. Avoid processed foods and choose low-phosphorus options.
  • Ensure adequate nutrition: CKD patients may be at risk for malnutrition due to dietary restrictions. We will ensure that you are getting the nutrients you need through a balanced, kidney-friendly diet.

She is warm, friendly, and approachable, and all of her advice was incredibly helpful. Kat is very calm, and the way she explains everything makes it easy to understand that eating can be an enjoyable experience. You can eat and lose weight at the same time, with no effort. I highly recommend Kat to everyone.AK P.AK P. ★★★★★ I can only sing praises for Kat, she really has helped me transform. I have been struggling with disordered eating for many years which is why I started working with Kat. There is still some work I have to do but after working with her for a few months now not just my relationship with food but my outlook on life in general has significantly changed due to her warm and understanding attitude. It has helped me to fully open up to the process of unlearning and I feel so much more free. I highly, highly, highly recommend working with Kat or Dietician Fit in general!Hayley M.Hayley M. ★★★★★ I work with Kat for 3 months and felt so much more positive about myself - weight loss, more energy, more confident. I leant how to properly fuel my body and stay fuller for longer to curb those cravings! Kat was really lovely and I thoroughly enjoyed each session. I would highly recommend this service and hope to have a few more sessions in the New Year to make sure I am still on track!Tashiya M.Tashiya M. ★★★★★ As part of my on-going self learning and improvement, I found Isabella, a Performance Dietitian, who is based in London but has her own Singapore connection! I was able to work with Isabella over the last 3-4 months on truly breaking down my nutrition, especially in relation to optimising playing tennis and the gym-routine that works around that. "Eating more & sufficient recovery time" have been key parts of this learning experience, which I look forward to building on moving forward. Thank you, Isabella for listening and working with me.Alicia Porras L.Alicia Porras L. ★★★★★ I cannot be happier and appreciate more all the guidance that Kat has been giving me during these past couple of months. In a moment of stagnation, when I felt that for more than I trained or tried to eat well my weight kept fluctuating, I was recommended to contact Dietitian Fit, and chose Kat specifically because I needed a healthier relationship with food and to improve my mindset in general in terms of eating. I had eating disorders in the past and I've never felt as good with myself as I feel as of today. After two months, I lost 5.5kg of fat and gained an immense amount of confidence, I can finally see my muscles popping and my body feels great in general. This is not a diet, this is a lifestyle, and you learn how to eat consciously by respecting your own meal choices and taste without feeling you're sacrificing anything, because you don't. I've been a few times on holidays during this period of time and still managed to be in control with my body and mind, and losing fat. Kat is a brilliant, lovely professional and I cannot be more grateful of all I've learned thanks to her. Definitely recommended. 💖Lenus B.Lenus B. ★★★★★ Hello healthier people!I just want to say how amazed and greatful to my dietitian Marizaan I am!She been kind, thoughtful, understanding and very patient with my journey from a food addiction person with huge health problems and feeling constantly that I will die to a new me today who lost 8 kg in 3 months and 6 cm from waistline giving me the confidence of 20 year old who will live well over 100!I am a health professional and I proud myself with lots of knowledge including some in nutrition but I realised during these 3 months how many mistakes I was making and learned a lot! Today was my last session but as I am still finding my feet around nutrition and diet I decided to extend it for another 3 months! Hope at the end to be the new fully healthy and disciplined one! Bonus, stopped so many medications! Good luck! I sure feel top of the world! LenusLouise E.Louise E. ★★★★★ Matt R.Matt R. ★★★★★ Isabella provided me with a friendly professional service, she took the time to assess my personal and professional circumstances and created the best plan to suit me, always on hand to answer any follow questions and adjust any details to my plan.

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.

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!

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.

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.

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.

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!

Frequently Asked Questions

Chronic kidney disease (CKD) is a gradual and irreversible loss of kidney function. It a serious condition that affects millions of people around the world. It occurs when the kidneys are no longer able to function properly, leading to a buildup of waste products in the body. This can lead to a variety of complications, including high blood pressure, anemia, nerve damage, and bone disease.

The two main causes of CKD are type 1 or 2 diabetes, and high blood pressure (hypertension). Other causes can include having an autoimmune disease such as lupus, an inherited disease such as polycystic kidney disease, or having glomerulonephritis, which is an inflammatory disease causing damage to kidneys. 

Often, symptoms are not severe enough until the kidney disease is quite advanced. Here are some symptoms of advanced kidney disease:

  • Fatigue and low energy, with problems sleeping
  • Poor appetite
  • Trouble concentrating
  • Vomiting
  • Brittle nails and hair
  • Itching
  • Weight loss 
  • Bone pain
  • Urinating more often, especially at night
  • Swollen eyes, legs, ankles and feet

CKD cannot always be prevented, but the following can help reduce your risk:

  • Stop smoking and reducing alcohol intake. This can help reduce blood pressure and risk of other diseases associated with a higher risk of CKD.
  • Eating a healthy, balanced diet – aiming for a range of fruits & vegetables, wholegrain, dairy, lean protein (vegetarian and animal products if desired), and a lower intake of higher sugar, fat and salt/processed foods. 
  • Regular exercise – this can help lower blood pressure. Recommendations of 150 minutes of moderate intensity exercise per week (such as fast walking) + at least 2 strength training sessions a week to work muscles.
  • Some non-steroidal anti-inflammatories (NSAIDs) can increase risk of kidney disease if taken for longer than needed. 

Yes you will still be able to enjoy meals out! You may just have to be mindful about some factors such as salt & fluid intake and opting for certain choices more than others. This can be discussed with your dietitian for more detail and support.
