Nutritional Therapy Terms

Practitioners consider each individual to be unique and recommend personalised nutrition and lifestyle programmes rather than a ‘one size fits all’ approach. Practitioners never recommend nutritional therapy as a replacement for medical advice and always refer any client with ‘red flag’ signs or symptoms to their medical professional. They will also frequently work alongside a medical professional and will communicate with other healthcare professionals involved in the client’s care to explain any nutritional therapy programme that has been provided.

The Nutritional Therapist (NT) requests that the Client notes the following:

  • The degree of benefit obtainable from Nutritional Therapy may vary between clients with similar health problems and following a similar Nutritional Therapy programme.
  • Nutritional advice will be tailored to support health conditions and/or health concerns identified and agreed between both parties.
  • Nutritional therapists are not permitted to diagnose, or claim to treat medical conditions.
  • Nutritional advice is not a substitute for professional medical advice and/or treatment.
  • Your Nutritional Therapist may recommend food supplements and/or functional testing as part of your Nutritional Therapy programme and may receive a commission on these products or services.
  • Standards of professional practice in Nutritional Therapy are governed by the CNHC Code of Conduct.
  • This document only covers the practice of Nutritional Therapy within this consultation, and your practitioner will make it clear if he or she intends to step outside this boundary.

The Client understands and agrees to the following:

  • I am responsible for contacting my GP about any health concerns.
  • If I am receiving treatment from my GP, or any other medical provider, I should tell him/her about any nutritional strategy provided by my nutritional therapist. This is necessary because of any possible reaction between medication and the nutritional programme.
  • It is important that I tell my nutritional therapist about any medical diagnosis, medication, herbal medicine, or food supplements, I am taking as this may affect the nutritional programme.
  • If I am unclear about the agreed nutritional therapy programme/food supplement doses/time period, I should contact my nutritional therapist promptly for clarification.
  • I understand that the advice is personal to me and may not be appropriate for others.
  • I must contact my nutritional therapist should I wish to continue any specified supplement programme for longer than the original agreed period, to avoid any potential adverse reactions.
  • Recording consultations using any form of electronic media is not allowed without the written permission of both me and my Nutritional Therapist.

Professional Standards

I will always strive to give you the most up to date relevant advice and recommendations, by making sure that I am up to date with the latest research.

I will provide clear written guidance after each consultation.I will be available to answer brief questions by e-mail or phone. Please note that is not an alternative to proper follow-up appointments.


An initial consultation lasts around 75-90 minutes. Follow-up sessions are 50 minutes. 


All appointment cancellations must be completed 48 hours in advance. Failure to cancel within 48 hours will still require full payment for the cost of the scheduled appointment.

How can I pay for my sessions

All services may be paid with cash, cheque or bank transfer card prior to the start of the service.  Make all cheques payable to Kaysha Thomas. 

Record keeping

I will keep your records confidential and secure and will not discuss your personal details with anyone else without your permission (such as writing to your GP or consultant, or discussing with a family member – except as below).

Eating Disorder Recovery

Nutritional Therapy alone is not accepted as a suitable approach for managing individuals with an active eating disorder (or even a history of the same). Therefore, when working with clients with an eating disorder, or history of an eating disorder, I must work in collaboration with other healthcare and medical professionals as part of a multi-disciplinary team. Depending on the situation, this may include working with a psychotherapist, counsellor, CBT specialist plus the client’s GP and possibly also a dietician. 

Children’s Consultations

Consultations with children (under age 15) must be with their parent, guardian or other appointed adult, and similarly for vulnerable adults with needs for special support.


The degree of benefit obtainable from Nutritional Therapy may vary between clients with similar health problems and following a similar Nutritional Therapy programme.
