Welcome to the site! We offer a range of high-quality services to clients looking to achieve better health, physique, or training performance. Founded by Registered Nutritionist Jonathan Griffiths (BSc Hons, ANutr.), Composition Consultant is a results focused consultancy specializing in the provision of nutrition services for clients.


Whilst providing experienced, expert advice in improving body composition, we avoid using cookie-cutter plans and programming in peoples diets. All of our clients are treated as individuals, with lifestyle and health circumstances being taken into consideration upon consultation. 

Jonathan has been in the nutrition industry, studying carefully for nearly 15 years.  He has also undertaken several courses surrounding human health, including Medical Science and a Nutrition and Herbal Science certification. Over that span of time, we have seen fad diets come and go. With the amount of misinformation online, we decided to uncover the truth. We have been using the most up to date scientific literature, as well as experience from working with hundreds of individuals with unique health situations. We recognized a gap in the market for affordable, yet high quality diet coaching. From there, Composition Consultant was formed.


Our ethos is to provide an affordable, yet highly customized service to both sportspeople and general public. Our experience comes from competing in bodybuilding competitions within the UK, including BNBF and UKBFF with top placings. In addition, hundreds of people have received vital advice that has impacted positively on their health and general well-being.

Here are just some of the conditions we have successfully alleviated symptoms of, or in some cases, put into remission:

  • Bone health

  • Cognitive disorders (Depression, Anxiety, ADHD)

  • Chronic kidney disease

  • Diabetes

  • Digestive health (IBS, Crohn's, Acid Reflux, Constipation)

  • Heart health

  • Obesity and weight management

  • Metabolic disease

  • Rheumatoid and Osteoarthritis

  • Vitamin deficiencies

Before taking on any clients with the above conditions, it is strongly suggested to utilize the consultations. This will allow us to consolidate a suitable program going forward.​
