Experts in fitness and nutrition share practical guidance on making referrals, coordinating care, and setting clear boundaries. Learn how to stay involved, provide meaningful support, and follow up after a referral. ### Refer Clients to Qualified Dietitians Clients sometimes ask for nutritional support beyond my scope of practice as a Personal Trainer and S&C Coach. This is, in my opinion, because of the multitude of voices on social media and even other trainers offering things beyond the scope of what they are insured and qualified to deliver, meaning most people assume a trainer can do more than they can. As trainers, we can advise but not prescribe. We can review a food diary; we can suggest calorie and macronutrient targets using theoretical equations and suggest healthier food swaps. We cannot, however, give full nutrition plans or prescribe a specific diet or accomodate diets around medical conditions (diabetes, crohns etc). For any clients wishing for this level of depth, I would refer to a registered nutritionist or a dietitian who would be qualified to deliver on this. Explaining the limits of your scope of practice and offering an expert referral makes most clients have more respect for me for staying in my lane and signposting them effectively. *— [Richard Bennett](https://www.linkedin.com/in/richard-bennett-20a977133), Strength & Conditioning Coach / Personal Trainer, Calibre Performance Coaching* --- ### Coordinate Care With Nutrition Specialists Being qualified in both personal training and performance nutrition gives me plenty I can help with, but it doesn't mean every nutrition question is mine to answer. I'm comfortable saying when something needs a dietitian or another healthcare professional to step in. Clients deserve proper support, and having a qualification doesn't mean you should pretend to know everything. I often say something like "I can help you with fuelling your training and building eating habits that work for you. But what you're describing needs someone with more specialist experience in this area. I can help you find that person, and we can keep working on your training alongside their advice." I think the delicacy and the follow-through really matters. Telling someone to "speak to a professional" can leave them wondering who to contact or what to ask. Where possible, I'd help them find an appropriate practitioner and (with their permission) share relevant information so they don't have to explain everything again. Often we can still work on appropriate gym goals while they get that support. If their health means training needs adjusting, we adjust it. Being honest about your limits and staying involved is far more reassuring than confidently giving advice you're not equipped to give. *— [Mr Michael Ulloa](https://uk.linkedin.com/in/michaelulloapt), Personal Trainer, Michael Ulloa* --- ### Define Boundaries and Maintain Coaching I would make the boundary clear without making the client feel like they asked the wrong question. I am NCSF and AFAA certified. I am not a registered dietitian, and I would not turn a fitness conversation into an individualized nutrition treatment plan. My script would be: 'I can help you with the workout and with making exercise fit your week. That nutrition question needs a registered dietitian. I do not want to guess with something that deserves the right expertise.' Then I would ask what they want help understanding so they can take a clear question to that professional. Questions about managing a medical condition, interpreting symptoms, or changing medication belong with their medical team. A trainer does not need to have an answer to everything to be helpful. There is still plenty we can work on together. We can choose a manageable training schedule, simplify the home setup, and give them a backup workout for a busy day. The referral does not have to stop the coaching relationship. It defines what each person is there to do. Knowing where your expertise stops is part of being useful. *— [Jacob Siwicki](https://www.linkedin.com/in/jacob-siwicki-000), Founder, Siwicki Fitness* --- ### Provide Direct Referrals and Continue Support The line I work to is short. I can teach nutrition. I can't treat anybody. I'm a certified personal trainer and nutritionist, not a registered dietitian, and those are different jobs with different training behind them. So when a question lands on the other side of that line, I say so out loud instead of hedging. The ones that cross it are predictable. Anything attached to a diagnosis. Anything involving a prescription, which these days usually means a GLP-1. Pregnancy. A gut issue that's been dragging on for months. Somebody wanting to stack supplements on top of medication they're already taking. Here's the script, and it's short on purpose: "That's a fair question and it deserves a proper answer, which puts it past me. I'm a trainer and a nutritionist, not a dietitian, so I'm not the person to build you a plan around that. What I can do is the training and the general nutrition around it. I'd rather hand the rest to somebody who does it properly. Want me to point you at a name?" Then you point them at a name. That part is the whole thing. A referral you don't follow through on just reads as a brush off. Telling somebody to go google "dietitian near me" isn't a handoff, it's a shrug. An actual name, an actual clinic, something they can click, costs you almost nothing and it's the difference between a limit and a dead end. Trainers worry that handing a client off makes them look like they don't know their job. I think it works the other way. People can tell when you're guessing, right? The moment you say "that part isn't mine, here's who it belongs to," everything else you tell them carries more weight. And a limit isn't the same as stopping. There's a lot of ground on my side of it. Protein targets and how somebody actually hits one on a normal Tuesday. What to eat around training and when. Reading a label without falling for the front of the box. Sleep. Water. The unglamorous stuff that moves most people further than any clever plan. I keep working on that while the dietitian handles the clinical end, so the two run in parallel and nobody sits waiting. One more thing that saves trouble. Say where the line is before anyone walks up to it. If people know from the start what you do and what you don't, the handoff isn't a letdown. It's just the plan working. *— [Waleed Hegab](https://www.linkedin.com/in/waleed-hegab), Founder, OrganiiLand* --- ### Follow Up After Dietitian Referrals "I'm a certified nutrition coach, not a dietitian, so my line is simple: I coach habits for healthy people, and anything medical goes to a registered dietitian." As a NASM-certified nutrition coach, I can help clients with things like protein targets, portion sizes, meal timing around workouts, and building better grocery habits. Where I stop is anything that involves treating a medical condition. If a client mentions diabetes, kidney issues, a digestive disorder, pregnancy complications, or a history of disordered eating, that's when I bring in a registered dietitian. Those situations need someone trained in medical nutrition therapy, and guessing could hurt them. The script I use goes something like this: "That's a great question, and it deserves a better answer than I can give you. This is outside what I'm trained to handle safely, so I want you working with a registered dietitian on this part. I'll keep coaching your training and the everyday habits we've been building, and once you have their plan, send it to me so I can make sure your workouts support it." Clients don't hear it as "I can't help you." They hear that I'm adding someone to their team. The key is that I don't let go of them. I stay involved, I line up my coaching with the dietitian's plan, and I follow up in a week to ask how the appointment went. That follow-up is what builds the trust. *— [Nelly Flaque](https://www.linkedin.com/in/nellyfitness/), Personal Trainer, NASM-CPT, Nelly F Fitness* --- ### Related Articles - [Give Nutrition Support in Personal Training Without Overstepping](https://fitnessinterview.com/qa/give-nutrition-support-in-personal-training-without-overstepping) - [Stay in Scope With Nutrition Coaching for Fitness Clients](https://fitnessinterview.com/qa/stay-in-scope-with-nutrition-coaching-for-fitness-clients) - [Fitness Coaches Share Boundaries That Keep Nutrition Guidance Helpful and Ethical](https://fitnessinterview.com/qa/fitness-coaches-share-boundaries-that-keep-nutrition-guidance-helpful-and-ethical)
