"Dietitian" and "nutritionist" get used as if they mean the same thing. They don't — and when you're dealing with a real health condition, the difference matters.

Registered Dietitian (RD)

In South Africa a registered dietitian has completed a university degree in dietetics plus supervised clinical training, and is registered with the Health Professions Council of South Africa (HPCSA). That registration means they're qualified and legally recognised to provide medical nutrition therapy — the evidence-based nutrition treatment of conditions like diabetes, high cholesterol, IBS, kidney disease, and weight management including GLP-1 support. It's a regulated, accountable profession.

"Nutritionist"

"Nutritionist" is a much broader, less tightly regulated term. Some people using it have excellent qualifications; others have done a short course. The title alone doesn't guarantee clinical training or professional registration, which is why it's worth checking credentials rather than assuming.

What this means for you

For general wellness, plenty of practitioners can help. But if you have a medical condition — or you're navigating something like GLP-1 medication where getting protein, nutrients and side-effects right genuinely matters — you want a registered dietitian. For the record: I'm a registered dietitian, HPCSA-registered and an ADSA member since 2004, with a nutrition degree from UCT and a professional chef qualification on top. Always feel free to ask any practitioner for their registration details — a good one will be glad you did.
