The honest answer is that you do not need to prepare much at all. But if it would settle your nerves, here is what actually helps.
This is the one I want to say before anything else, because so many people quietly do it. There is a strong urge to eat perfectly for a week before a dietitian appointment, to arrive with something respectable to report. Please do not put yourself through that. It only produces a tidy week that looks nothing like your real life, which means we would end up working from a version of you that does not exist. Come as you actually are, in the middle of whatever is genuinely happening. The messy, ordinary, contradictory version is the useful one, and it is not going to shock me.
If you want something concrete to do, keep it small. It helps to have a list of any medications and supplements you take, including the ones you are not sure still matter. If you have had recent bloodwork or any relevant test results, having them on hand is useful, though it is not essential and we can always look later. If you have a diagnosis, a referral note, or anything a doctor has told you about food, that is worth mentioning. And if you plan to submit to insurance, check whether your plan needs a referral or a specific receipt format before the session rather than after.
People often assume they should arrive with everything they ate logged and measured. You do not need to, and for many people I would gently steer away from it. For anyone with a history of dieting or disordered eating, tracking can pull you straight back into surveillance and self judgment, which is usually the opposite of where we are trying to go. If noticing patterns becomes useful later, we can find a way to do that which does not feel like an audit. A rough sense of what a normal day looks like for you is more than enough to start.
The most valuable preparation is not about food at all. It is a few minutes of honesty with yourself about what made you reach out. Maybe you are exhausted by thinking about eating all day. Maybe evenings feel out of control, or your stomach has been miserable, or you have been told to change something and you do not know how. You do not need it polished or well phrased. Even a vague sense of this feels hard and I do not know why is a completely legitimate place to begin, and often more useful than a neat list of goals.
If your session is virtual, it helps to find a spot where you can speak freely, which matters more than a good camera. Headphones make a real difference, both for hearing and for privacy if there are other people home. Have water nearby, and know that you are welcome to eat during a session if that is when you have time. Give yourself a few minutes on either side rather than sprinting in from something else. Feeling rushed at the start tends to make everything harder to say.
What actually makes a first appointment work is not preparation. It is having somewhere safe enough to be honest. My job is to ask decent questions and listen carefully to what you say, and none of that depends on you arriving organized. As a Registered Dietitian with the College of Dietitians of Ontario, I offer a free introductory call, which is really just a conversation about what you are carrying and whether working together feels right. There is no cost, nothing to prepare, and no pressure to book anything afterward.
Only if you genuinely want to, and even then it is not required. Food tracking can be a helpful window for some people and a fast route back into anxiety and self criticism for others, particularly anyone with a dieting or eating disorder history. Nothing is lost by arriving without it. A general sense of how your days tend to go gives us plenty to work with, and if any kind of noticing would help down the line, we can figure out a version that feels safe rather than surveillant.
That is a very common way to arrive, and it is genuinely fine. Plenty of people come in knowing only that something about eating feels hard and that they are tired of it. Not having goals is not a sign you are unprepared or wasting the appointment. Often the first stretch of work is simply sorting out what you actually want, underneath what you have been told you should want. You are allowed to show up uncertain and let the goals surface as we talk.
The first call is free, and there is no pressure to continue. It is just a calm conversation about what you are looking for.
