She designed a diet that hits all my nutrition target

Ash is extremely knowledgable and has a flexible approach to suit your lifestyle. I’m mostly vegetarian, but I was worried about my nutrition intake. She designed a diet that hits all my nutrition targets and suggested the right supplements. She’s also great with communication!

She helped me see results in a few weeks

Ash is great at understanding what you want to achieve and making it simple to get there. She gives you loads of meal options to choose from and educates you enough to make smarter nutrition choices on your own. Over and above this she is also easy and fun to talk to.

2. Lila Bruk & Associates – Registered Dietitians

Website: http://www.lilabruk.co.za/

Address: Blubird Medical Centre, 1st floor, Blubird Shopping Centre

Contact: 011 880 9156 / [email protected]

Hours: Monday-Friday, 8:00 AM – 5:00 PM 

Dealing with a chronic condition like diabetes or high cholesterol can be tough if you don’t have the right support. That’s where Lila Bruk & Associates stands out. 

This clinic has a whole team that focuses on helping people manage things like metabolic issues, tough gastrointestinal problems such as IBS or Celiac disease, and weight goals.

Lila is an Integrative and Functional Nutrition Practitioner, so she looks at every aspect of your health, not just your diet. You can get meal plans that are actually built using your DNA, blood tests, and body composition data. Everything feels truly personal. 

The only tricky part is the clinic’s hours. The whole team’s off on weekends, so busy professionals might struggle to book.

Still, plenty of clients say the expert advice is worth rearranging your day for.

My programme of eating and taking supplements is achievable

I have been seeing Lila since 2019 for dietary, nutrition and overall wellness needs. She has been lovely to work with. My programme of eating and taking supplements is achievable. I don’t feel overwhelmed. She has also been straight with me around taking medication for my cholesterol which I was trying to curb through diet alone but it wasn’t working. I am very thankful for Lila’s warm but also no fuss approach. She makes you think of food and eating in what is manageable according to your lifestyle and I really appreciate that.

Lila gave me personalised, practical advice that fit my lifestyle

Lila has completely changed the way I manage my health. As a diabetic, I needed more than just help with my diet — I needed someone who understood how to balance my nutrition with controlling my sugar levels. Lila gave me personalised, practical advice that fit my lifestyle and made a real difference.

She’s supportive, knowledgeable, and genuinely cares about your success. Thanks to her, I feel healthier, more in control, and more confident managing my diabetes. I’m so grateful for her guidance and would highly recommend her to anyone looking for real, lasting change. 

Thank you, Lila!

3. Janene Sacks Registered Dietician

Website: http://www.jsacksdietician.co.za/

Address: Waverley Health and Wellness Centre, 17 Lennox St, Savoy Estate

Contact: +27 82 561 0507 / [email protected]

Hours: Monday-Tuesday, 7:30 AM – 5:00 PM | Wednesday, 7:00 AM – 5:00 PM | Thursday, 7:30 AM – 5:30 PM | Friday, 8:30 AM – 1:00 PM 

Figuring out what to eat while managing a specific illness often requires more than just generic advice. Janene Sacks steps up by providing individually calculated diet plans paired with clear, disease-specific dietary education and custom seven-day menus. 

She teaches you exactly which foods to eat or avoid to help ease your symptoms, even if you love indulging in famous foods in South Africa. Her customized meal plans lay out pre-calculated portion sizes in a format that’s incredibly simple to follow. 

If you’re curious about your genetics, she’s also an accredited practitioner for DNA-based nutrition testing. Plus, she handles telehealth consultations globally if you prefer to chat from home. 

One drawback is her unavailability during the weekends and the early closing time on Fridays.

She keeps you motivated, is never judgemental if you slip up

Janene is one of the best dietitians I know. I have been going to her for several years and have now lost 50 kgs since I first started. She keeps you motivated, is never judgemental if you slip up, has a calm and lovely manner and if you want to have a healthy eating plan and way of life, you will not go wrong. Make an appointment now. You wont be sorry.

I have actually lost weight and added new habits to my daily life

I have tried so many different programs over the years but Janene has guided me through her program, in fact she has created a program that suits the needs of my body, that I have actually lost weight and added new habits to my daily life. I’ve watched my weight drop so rapidly, which was a huge goal for me!

She will analyze what you are eating, tell you what your body is missing and fix your diet which will truly make wonders!

4. Core Nutrition Sandton Morningside

Website: http://www.corenutrition.co.za/

Address: Sandton Sports Medicine, Block G, Rochester Place, 173 Rivonia Road

Contact: +27 79 215 2034 / [email protected]

Hours: Monday-Friday, 7:00 AM – 5:00 PM | Saturday, 7:00 AM – 11:00 AM

Core Nutrition starts your journey with a detailed assessment that combines your blood-test results, InBody body-composition stats, and dietary history to build a bulletproof nutrition plan. 

Our colleague who’s frequent at a gym actually booked a session here last month and couldn’t stop raving about how detailed their sports nutrition advice was.

They handle everything from medical nutrition therapy for weight management to pediatric advice for fussy eaters. If you recently got a health screening, you can easily bring those results here for a more customized plan. 

But there’s a catch with their process. The full package requires a one-hour initial meeting, followed by a totally separate consultation just to get your diet plan and results.

Her warm and approachable demeanor made the entire experience enjoyable

I recently had the pleasure of having a consult with an exceptional dietitian who not only understood my specific dietary needs but also displayed a remarkable level of friendliness and approachability. Her expertise in crafting a personalized nutrition plan tailored to my requirements was truly impressive. Moreover, her warm and approachable demeanor made the entire experience enjoyable and motivating. I greatly appreciate Core Nutritions dedication to helping me achieve my health goals and would highly recommend them to anyone seeking effective and personable dietary guidance.

I learnt so much about nutrition and health in general

She is incredible. I learnt so much about nutrition and health in general and the diet plan made it easy for me to reach my goals and it improved my way of life in general. She is very caring and genuinely wants the best for you and for you to reach your goals. She changed the way I look at a “diet” from a bad thing to a great thing. I had the best experience here and would 100% recommend to anyone.

Her expertise, guidance, and support have been invaluable. Tabitha is knowledgeable, approachable, and empathetic – exactly what you want in a healthcare professional.

She’s a fantastic resource

​I highly recommend Tabitha! Instead of just giving me a meal plan, she taught me how to understand food. She explained nutrients, showed me how to read labels, and made healthy eating feel easy and totally manageable. She’s a fantastic resource for anyone wanting to learn how to make better choices for life.
