Nutrition coaching can be incredibly helpful, but it has limits. This post breaks down scope of practice: what nutrition coaches can do, what we can't do, and why those boundaries exist in the first place. We walk through how Black Iron coaches support clients through nutrition education, behavior change, and lifestyle habits, while also recognizing when something falls outside the role of a coach. Topics include the differences between dietitians, nutritionists, and coaches, how state regulations shape what different credentials allow, and why working within those boundaries protects both clients and professionals. We also cover the warning signs coaches watch for: medical concerns, signs of disordered eating, psychological red flags, or expectations built around extreme diets and quick fixes. Sometimes these situations simply require collaboration with other professionals. Other times they mean referring someone to a medical provider or therapist who can better support what they're dealing with. Scope of practice is about making sure people get the right support from the right professionals so their health, safety, and long-term progress come first.
