Quick answer
A nutritionist (or registered dietitian) is a credentialed specialist who provides evidence-based nutritional guidance and, in many states, is the only professional legally permitted to provide medical nutrition therapy. A health coach takes a broader behavioral approach — helping clients build habits, set goals, and make sustainable lifestyle changes — but is not licensed to diagnose conditions or prescribe medical diets.
For medical conditions or clinical nutritional needs, a Registered Dietitian is the appropriate professional — and the only one legally qualified to provide medical nutrition therapy in most states. For general wellness, habit formation, and lifestyle change, a qualified health coach can provide valuable ongoing support. When evaluating a health coach, look for reputable certification programs and ask clearly what falls outside their scope of practice.
