Connect the dots bewteen nutrition and your health.
I’ve always believed that food is about so much more than what’s on your plate. It’s about how you feel when you wake up in the morning, the energy you have for your children, the confidence you have in your body, and the freedom to enjoy life without constantly worrying about what you should or shouldn’t be eating.
As a Christian and Registered Dietitian, my journey has led me to a place where I see nutrition differently. I don’t believe in quick fixes, rigid meal plans or a one-size-fits-all approach. I believe in taking the time to understand you: your story, your symptoms, your lifestyle, your goals and the unique way your body works.
My passion is helping people connect the dots between nutrition and their health, whether that means supporting a woman through hormonal or fertility challenges, helping a child develop a healthy relationship with food, improving gut health, or simply helping a family make healthier choices that are realistic for everyday life.
Together, we’ll move beyond simply asking “What should I eat?” and start asking the more important question: “What does my body need?”

Patient stories
Rainbow baby
Marietta Roets
Earlier in January, I faced a heart-wrenching loss when I miscarried. For months, I struggled to conceive again. Deciding to take a break from medication, I booked my first consultation with Alet, confident she could help me in a more holistic way. My favorite part of the process was the seeding method. The best part was that it didn't involve any strange or expensive foods.
As a mom of two, the meals were easy to prepare and absolutely delicious.
After visiting the doctor and starting the stimulation process alongside Alet's meal plan, I received the best news ever - we are pregnant with our rainbow baby! Amidst all the nerves and excitement, Alet reassured me. She explained how we would adjust the meal plan to accommodate my growing baby, ensuring a healthy body for me to nurture this miracle.
Real transformation
Lize Kriek
“Alet is one of the most passionate and intentional individuals I know when it comes to one’s health. She successfully helped me with an incredible fertility diet and hormone balance diet.
Not only giving me a diet (actually a lifestyle) but a deep understanding and an empowering why behind following it and putting it in action. Her approach is holistic which I love. She puts her whole heart into getting you where you need to be, with amazing diets, rich and relevant knowledge, accountability and wonderful consultations.
She really goes the extra 100 miles no matter what and really wants the best for her clients and makes one feel it is actually achievable.”

“I reached out to Alet to help me lose weight before summer and achieve my bikini-ready body. Within two months, I noticed a significant transformation and was able to confidently enjoy my holiday.
The meal plan was full of delicious and easy-to-prepare meals, and the exercises were manageable with achievable goals. Alet supported me throughout the entire process, weighing me in every week.
A few months later, I decided I wanted to get pregnant, and Alet provided me with a fertility diet plan. Soon after, I successfully became pregnant. Alet is an amazing dietician, and I highly recommend booking her—you won’t regret it!“

In 2022 was ons bevoorreg (groot guns) om in die eerste maand wat ons met n gesin wou begin swanger te raak. Dit was alles so maklik en eenvoudig. Twee jaar later toe ons probeer vir baba nommer 2 het die prentjie wel baie anders gelyk. 4 Chemiese swangerskappe (toets positief maar voor 6 weke begin die telling verminder). Elke keer groot hoop en drome en dan n selfs groter hartseer.
Ek ken vir Alet al baie jare (dankie tog) en haar miskraam storie het my hart gegryp. Ek het toe uitgereik en ons het die proses om my liggaam te herstel saam begin. Sy het alles verduidelik in n taal wat ek verstaan. Ek sal nooit ons eerste afspraak vergeet nie. Haar woorde: “Stap 1: ons bid saam julle en ons vertrou Jesus vir hierdie baba” Sy is gefokus om met Jesus te co-labour en dit sal ek nooit vergeet nie.
Ons het n 3 maande proses begin om my liggaam en selle te herstel deur wat ek eet. Ek was skepties, maar ek het geweet hierdie is wat ek bereid is om te doen in gehoorsaamheid. Die tempel te herstel. Na 3 maande het ons die positiewe toets gekry. My baba is nou 4 maande oud.
Alet, dankie bo alles vir jou liefde en hoop wat jy saai.
