Your GP just mentioned the word pre-diabetic, or you're a new parent trying to get a picky toddler to gain weight, and Google is throwing a dozen names at you with no way to tell them apart. Johannesburg has plenty of registered dietitians, but the right fit depends on what you're actually dealing with. Between them, the dietitians in Johannesburg on this page have logged 441 Google reviews, almost all of it rated 4.9 or 5, so the deciding factor here is fit, not whether the reviews hold up.
Short answer: Ash The Dietitian and Core Nutrition Sandton Morningside both hold perfect 5.0 ratings, at 228 reviews and 60 reviews respectively, with Ash The Dietitian the clear leader on volume. Taryn Bortz (4.9, 66 reviews) in Craighall is close behind. If you're managing a specific condition like Crohn's disease or diabetes, Ashleigh Caradas and Taryn Bortz both have reviewers describing exactly that kind of work.

Our take: Consistent, specific praise across very different needs, diabetes, menopause, a child's weight gain, is a good sign of range rather than a one-trick approach. Ranks just behind our top pick mostly on review volume.

Our take: The reviewer-reported pre-diabetes reversal is a striking result from one specific client's experience, not a guarantee for everyone, but it lines up with the practice's broader reputation for evidence-based guidance. Ranks fourth mostly on review volume.

Our take: The range here, from routine weight goals to Crohn's disease to eating disorder support for a teen, suggests real clinical breadth. It ranks fifth mainly because it has fewer and slightly older reviews than the rest of this list, not because the feedback is weaker.

How We Rank These Dietitians
Rating is the live Google average for each practice. Review volume shows how many clients have actually rated them, weighed against every other dietitian we checked in Johannesburg. Confidence combines both, so a high average built on hundreds of reviews counts for more than one built on a handful. Recency tracks how recently people are still reviewing, a sign the experience described is still current. No business can pay to change any of these numbers.
What Does Seeing a Dietitian Cost in Johannesburg? (2026)
Costs vary by whether you’re paying cash or claiming through medical aid, how long the initial consultation runs, and whether extras like DNA testing or corporate programs are involved. Some practices offer online consultations at a different rate than in-person visits. Ask directly for the initial consultation fee and whether your medical aid plan covers dietitian visits before you book.
Dietitians Across Johannesburg
This list spans Dunkeld West and Randburg, Craighall Park, Sandton’s Morningside area, Birnam, and Parktown North, so there’s real coverage across the northern suburbs. If you’re searching for a dietitian near me in Johannesburg, weigh how often you’ll need follow-up visits against how far you’re willing to travel, since some practices also offer online consultations if distance is the main barrier.
What to Ask Before You Book a Dietitian
- Do you have experience with my specific concern, like diabetes, Crohn’s, or an eating disorder?
- Do you offer online consultations if I can’t make it in person?
- How do you build a plan around my existing food preferences and allergies?
- How often will we check in, and what does progress tracking look like?
- Do you work with my medical aid, or is this an out-of-pocket cost?
Frequently asked questions
Are these rankings paid?
No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position.
How did you choose these dietitians?
We compared registered dietitians in Johannesburg with a real Google track record on rating, review volume, and how recently people are still reviewing them, then read the reviews for details on specific conditions treated and follow-up support.
How often is this updated?
We last verified this list in July 2026 and refresh it as ratings and review counts change.
Do I need a doctor’s referral to see a dietitian?
Not usually. Most dietitians accept clients directly, though your medical aid plan may have its own requirements for reimbursement.
Can a dietitian help with a medical condition, not just weight loss?
Yes, based on the reviews here, dietitians on this list have worked with clients managing diabetes, Crohn’s disease, and other conditions alongside general nutrition goals.
The Bottom Line
Ash The Dietitian is the safe default on scale and consistency alone, but if you’re dealing with a specific medical condition rather than general weight goals, Lila Bruk & Associates or Ashleigh Caradas both have reviewers describing exactly that kind of work. Bring a food diary or recent bloodwork to your first session so the dietitian isn’t starting from zero.
