Instagram auto-replies for nutritionists and dietitians
Instagram DM automation lets a nutritionist or dietitian send a food-label guide, a lunchbox plan or consultation details to everyone who comments or messages a chosen word. It handles the questions that have one right answer, such as fees, online sessions and what to bring, and leaves anything about a person's own health to you.

Comment words for nutritionists and dietitians
Ask people to comment one word in your caption or video. Each word sends something different.
- LABELS
- A one-page guide to reading a food label, with a breakfast cereal box worked through line by line.
- LUNCHBOX
- Five school-day lunches with a shopping list, plus ideas for children who bring half the box home again.
- PROTEIN
- A vegetarian protein list for the meals in your Reel, built on foods your audience already cooks, such as dal, paneer, tofu and curd.
- GROCERY
- Your weekly grocery list sorted by supermarket aisle, with the high-fibre choices marked.
- RAMADAN
- A suhoor and iftar planner for the fasting month, with a checklist for drinking enough between sunset and dawn.
- DIARY
- A three-day food and symptom diary, the same one you ask new clients to bring, offered privately through a Story.
- CONSULT
- How a first consultation works: the fee, how long it lasts, online or in person, and what to bring, such as recent blood test results.
4 set-ups to try
Each one shows the conversation it creates. After a comment, the first DM is plain text, as Meta requires, and the link follows once they answer.
Label guide from a supermarket Reel
Someone comments on your post
LABELSPublic reply under their comment
Just sent it, have a look in your DMs 🛒First DM (plain text)
Thanks for watching. The guide takes one cereal box and explains every line of its label, so any pack makes sense afterwards. Would you like a copy? Reply to this message and I'll send it over.Yes pleaseHow to read a food labelGet the guideSupermarket Reels reach people who would never search for a dietitian. The guide is useful on its own, and everyone who replies becomes a conversation you can pick up when they're ready to book. Write three or four public replies: DMFast picks one at random for each comment, so the thread isn't the same line over and over.
Symptom diary, sent privately after a Story
Replied to your story
DIARYThanks for replying. The diary has room for three days of meals, drinks and symptoms. One tip: fill it in as you go, not from memory at bedtime. Any questions about it? Ask me here and I'll answer myself.3-day food and symptom diaryGet the diaryFew people will comment IBS or PCOS under a post, because anyone can read it. A Story reply reaches only your DMs. The diary is also what you'd ask a new client to bring, so people who fill it in arrive at a first appointment with the groundwork done.
Fees and first-visit details on request
CONSULTHi, thanks for asking about a consultation. Is this your first visit? The page below covers the fee, how long the first session takes, online and in-person options, and what to bring, including recent blood test results if you have them.Your first consultationSee fees and timesAdd CONSULTATION, FEES and APPOINTMENT to the same reply. Matching works on whole words, so CONSULT alone won't catch “consultation”. The card covers logistics only; questions about someone's own symptoms wait for the appointment, or for your personal reply.
Lunchbox plan for the weeks before term
Someone comments on your post
LUNCHBOXPublic reply under their comment
Plan's in your DMs, happy packing 🍎First DM (plain text)
Hi, thanks for the comment. The plan has five school-day lunches, a shopping list and a few ideas for children who bring half of it home. Shall I send it? Just reply here.Yes please5-day school lunchbox planGet the planParents look for lunchbox ideas in the run-up to term, so a Reel posted then meets them at the right moment. Turn on email capture: a parent who downloads the plan in August may want a family consultation in January, long after Instagram's 24-hour window has closed.

The DMs a nutrition practice gets, and who should answer
Most messages fall into two groups: practical questions with one right answer, and personal ones about a body, a diagnosis or a medicine. The first group can go to automation. The second needs a qualified person, and usually an appointment.
| Message | Automatic reply | Your reply, when |
|---|---|---|
| How much is a consultation? | CONSULT: fee, length, online or in person | They ask about a package of follow-ups or a reduced rate |
| Do you take my insurance? | The insurers or schemes you work with, if any | They need you to check their own cover or a referral |
| Can you just send me a meal plan? | How your plans are built and what they cost | They mention a condition, a pregnancy or a medicine |
| I think I have IBS. What should I cut out? | At most, a note that you'll reply personally | Always: cutting out foods comes after an assessment, not before |
| Which supplement should I take? | Nothing automatic | Always, since it depends on their health and anything else they take |
| What can my child eat for lunch? | LUNCHBOX | The child has an allergy, or the parent is worried about growth |
Tip: AI replies, on the Growth and Business plans, work only from the practice information you write. Put your fees, hours and the conditions you see in it, and add that symptoms, supplements and medicines are discussed in appointments. The AI then sticks to logistics and tells people someone will get back to them on the rest.
Posts that earn comments, and when to run them
- A supermarket walk-through, one aisle per Reel, ending with LABELS.
- A lunchbox Reel filmed the week before term starts, with LUNCHBOX in the caption.
- A day of vegetarian meals with the protein in each, ending with PROTEIN. Attach the word to this post only, or a genuine question such as “how much protein is in this?” on any other post would get the list rather than a reply to the question.
- A myth answered in under 30 seconds, such as whether eating late makes you gain weight, with a question in the caption so the comments become a Q&A.
- A Story series on bloating with a question sticker, ending with “reply DIARY” rather than a comment word.
- A carousel of suhoor ideas a week before Ramadan, with RAMADAN for the planner.
Nutrition has its own calendar. January brings resolutions, and the weeks before school starts bring lunchbox questions. March is National Nutrition Month in the US, and India marks National Nutrition Week from 1 to 7 September. Fasting periods such as Ramadan and Navratri raise questions about what to eat and when, and the festive season raises questions about sweets. Set each word up a week or two before its rush.
From a free guide to a first consultation
- A Reel or Story offers a guide. Commenters get a plain-text first message, and the guide follows once they reply.
- For bigger freebies, ask for an email before the link. Throwaway addresses are rejected, and the list downloads as a CSV for your newsletter tool.
- On Pro and above, anyone who stops before typing their email gets one reminder, timed to arrive while Instagram still lets you message them.
- Your emails, Stories and link-in-bio page invite people to book. Point the CONSULT card and the bio page at the same booking page.
- Health history, medicines and test results belong in your own intake form or practice software, never in an Instagram thread.
Practising in India? The DMFast store can sell a recipe book or a festive-season guide as a digital product, hand out a lead magnet in exchange for an email (and a phone number, if you ask for one), and take free or paid consultation bookings, with payment through Razorpay and no DMFast fee on sales. Elsewhere, point the card at the booking page you already use.
Rules for giving nutrition advice online
- Titles. In some countries “dietitian” is protected by law and “nutritionist” isn't: in the UK, only people registered with the Health and Care Professions Council may call themselves dietitians. Use the title you actually hold, in your bio, posts and auto-replies alike.
- Licences. In the US, dietitian licensing is decided state by state. Before the CONSULT reply offers an online session to someone in another state or country, check that you're allowed to see them.
- Health data. In the EU and the UK, information about health is a special category of personal data under GDPR, and in the US, HIPAA may apply depending on how your practice bills. Move symptoms and test results off Instagram and into your intake form.
- Claims. Describe what an appointment covers, not what it will achieve. Don't promise a weight by a date, a cure or a lower blood sugar reading. Rules on health claims differ by country, so check yours before you boost a post.
- Eating disorders. If a message hints at disordered eating, a calorie guide is the wrong reply. Answer yourself, and refer them on if eating disorders aren't your field.
- Instagram's limits. Each comment can get one private reply, within 7 days, and automated messages only reach people who wrote to you in the last 24 hours. Meta's API doesn't allow mass DMs to your followers.
Messages to copy
Questions people ask
Will the automation give people diet advice?
Only what you write. A keyword reply sends the same message to everyone who uses the word, so keep it to guides, fees and practical details. AI replies draw only on the practice information you provide, so leave personal advice out of that information and answer those messages yourself.
Someone commented PCOS publicly. How do I protect other people's privacy?
Give condition-specific guides a private route: a Story reply or a word sent by DM, which only you can see. Keep your public replies neutral as well. “Sent, check your DMs” is fine; “Sent you the PCOS guide” tells everyone what they asked for.
Why does the first message ask a question instead of sending the guide?
Instagram and Messenger allow only plain text in the first private reply to a comment: no links and no buttons. A question gets the person to reply, and once they do, the guide follows as a card with a button. Story replies and DM keywords skip that step because the person messaged you first.
Our clinic has a Facebook Page too. Does that work?
Yes. Comments on the Page's posts and messages to it in Messenger can get the same keyword replies. Story replies exist only on Instagram, so the DIARY set-up stays there.
What happens when a lunchbox Reel takes off?
Each person gets one answer a day from each auto-reply, and comments with links or promo spam are skipped. Instagram allows up to 750 private replies to comments an hour; DMFast stays under 700 and queues the rest, so everyone is answered in turn. Comments more than 7 days old can't get a private reply, so set the word up before you post.
