Ever wondered what's up with the terms “dietitian” and “nutritionist”? You are not alone! The internet, wellness gurus, and even some clinics use them conversely. But here's the thing: the professional you pick can seriously affect your health like your recovery, weight goals, hormones, and well-being down the road.
Both, nutritionist and dietitian can help you eat better, but they have very different training and roles. This guide will break it down simply, so you will know just who to go to if you are dealing with gut problems, aiming to lose weight, managing PCOS, or need a special diet.
