Key takeaways
- The usual dividing line is education vs prescription: explaining how a calorie target is calculated is different from prescribing a diet to treat a condition.
- Rules on nutrition advice vary by country and, in the US, by state, so check your own jurisdiction before you write your scope down.
- A target from a published formula such as Mifflin-St Jeor times an activity factor is a population estimate, not an individual prescription.
- Plan at least four referral triggers in advance: medication, diagnosed conditions, pregnancy and disordered eating.
- Your client agreement, intake form and language should all say the same thing about what you do and do not do.
Coaches can usually help clients understand and use calorie and macro targets as general education, but individualized dietary prescriptions for medical conditions are commonly reserved for licensed professionals. Where exactly the line sits depends on where you and your client live, so this is a framework for the conversation, not legal advice.
Not legal or medical advice
This article is general education. Scope-of-practice and title laws differ by jurisdiction and change over time. Confirm the rules where you work with your licensing board, a lawyer or your professional insurer, and direct clients with medical conditions or medication to their clinician.
Can a nutrition coach set calorie targets for clients?
In many places a coach can share a calorie estimate derived from a published formula as general education for healthy adults, but this depends on local law. Some jurisdictions regulate nutrition counseling or restrict titles such as "dietitian" and sometimes "nutritionist", while others leave general wellness coaching largely unregulated.
Whatever your rules, the safer framing is consistent: you are showing the client how an estimate works, not diagnosing or treating anything. Our post on BMR vs TDEE vs RMR is a clear explainer to share.
What is the difference between education and prescription?
Education explains general principles and how a number is calculated, while prescription tells a specific person what to eat to manage a condition. The first is information anyone could find in a textbook; the second applies clinical judgment to an individual's health.
| Usually education | Usually prescription |
|---|---|
| Explaining how TDEE is estimated | Setting a diet to manage diabetes or kidney disease |
| Sharing general protein ranges in g/kg | Adjusting intake around medication |
| Teaching how to read labels and log meals | Meal plans for a diagnosed digestive condition |
| Helping a client track and review their own data | Treating disordered eating |
A general illustration. Where the line falls legally depends on your jurisdiction.
How can you set targets as education, not a prescription?
Set targets from a transparent public formula and present them as an estimate the client can test, not an instruction. Two habits help: show the inputs (age, size, activity) so the client sees where the number comes from, and revise it from their own weight trend.
- Use the same formula your tools use; the TDEE calculator shows the working, and what is TDEE explains it.
- Say "an estimate to start from" rather than "your prescription".
- Review the number against two to three weeks of real data before changing it.
- Keep deficits moderate and follow the ranges in how many calories to lose weight.

2BIB group plans give each member an adaptive TDEE target and their own log, with your branding, while you stay in the coaching role.
When should a coach refer a client out?
A coach should refer a client to a clinician or registered dietitian whenever food advice could interact with a health condition, a medication or a risk of disordered eating. Decide the triggers in advance so the call is not made under pressure.
- Medication or a diagnosis: diabetes, kidney disease, heart conditions, digestive disorders, or GLP-1 medication (see what to eat on a GLP-1 for the general-education side).
- Pregnancy or breastfeeding, where needs differ and calorie restriction is not appropriate to coach.
- Signs of disordered eating: rigid rules, distress around food or compulsive logging.
- Under 18s, where adult formulas do not apply.
How do you write your scope into the client relationship?
Put your scope in writing in three places: the client agreement, the intake form and your marketing copy. They should say the same thing, namely what you offer, what you do not, and that clients with medical conditions need their clinician's sign-off.
- Agreement: state that coaching is educational and does not replace medical care.
- Intake: ask about conditions, medication and pregnancy, and record your referral.
- Marketing: avoid words like "treat", "cure" and "prescribe".
- Insurance: confirm your professional cover matches what you actually do.
