What is the best diet?

The best diet in the world is the one that you can actually stick to. It has to be practical, enjoyable, affordable and sustainable.

You should never be hungry or overfull and should always have energy through the day.

Everyone has their own specific needs and goals and our mission to make your meal plan as practical, enjoyable but yet effective to get you to where you want to be.

We look at you and your needs!

Shani is very professional and knowledgeable. She took time and effort to ensure I understand everything and she was open and honest about all my questions. Shani cares a lot about her patients and walks the extra mile. I would highly recommend her to anyone.



I would highly recommend Shani to any person who needs a dietician that listens and explains in detail what it means to diet. Shani is passionate, professional and knowledgeable in the field. My experience with Shani was exceptional, she puts a great deal of effort into a person's needs. I struggled to find a healthy balanced diet, the doctors gave me a list of foods I wasn't allowed to eat, but no meal plans were given or a list of foods you can eat. Shani helped me to explain the importance of certain foods and to follow a healthy and balanced diet without the foods I'm not allowed to eat, my meal plans were thoroughly discussed and she helped me to see things differently.



Jason van Heerden was recommended to me by another dietician mainly due to his specialization in sports nutrition. All my visits and interactions have been professional and insightful. He is extremely knowledgeable and is ever willing to share details with you so that you understand. He is always available and is ever willing to answer my myriad of questions with the same enthusiasm all the time. I will recommend Jason in a heart beat!



As a PCOS patient I’ve been battling for more than a year to lose a mere 3kg without success. A friend then recommended I meet with Jason to work out an easy-to-follow daily meal plan. It has now been 7 weeks since I visited Jason and have lost just over 4kg! He is an exceptional dietitian, and I would highly recommend him!



Jason is passionate about his job, professional with his clients and knowledgeable in the field, he is the Dietician you are looking for. My experience with him is exceptional, he puts a great deal of vigour into generating the way forward for the clients. He goes beyond a generic implementation of health and nutrition; he puts a great deal of effort into each person’s needs. My meal plans were thoroughly discussed according to my needs and I am feeling the changes already.
