CORE Nutrition

CORE healthy eating advice meets your personal requirements, with any dietary question answered.




CORE can advise on: dietary changes to feel healthier and energised; a balanced diet; portion size; making sound food choices; practical food and meal ideas; dietary myths, IBS and food allergy. CORE healthy eating sessions can be group based or 1-1. This in-depth service is unique due to the high-level qualification and experience of Dr Claire Tuck, the only Registered Nutritionist in North Wales. Over six years of nutrition training and over twenty years of experience brings you the best: an up to date, high-quality nutrition service based on research and experience.

Consultations can include a food diary analysis and detailed report; this consultation costs £50 (one hour consultation). Consultations without a food diary analysis cost £35.

Please contact us to book a nutrition consultation.

CORE can help you control your weight, whether you want to lose or gain weight. The focus is on enabling you to make changes that you decide upon, with specialist advice and assistance. Research has shown that specialised advice and the client being in control achieves the best results: maintaining weight change in the long term.

So this is the protocol: we meet, talk about past weight experiences and problems, focus on how to overcome these problems, look at current weight goals, and start on the path to weight change. The sessions are individualised to meet your needs, so we may cover a range of nutrition and exercise areas, depending on the identified problems and your specific needs (such as lack of motivation, poor eating habits (often due to past dieting), eating due to stress/boredom/loneliness/habit, learning how to cope with stress), and develop the best eating plan for you, making small changes. We focus on enabling you to enjoy life and food, not to be controlled by what you eat.


CORE weight control covers nutrition, exercise and behavioural change. All sessions are based on making lifelong changes to the type of food that is eaten, the amount of exercise that is taken, and the way that clients think and feel about their weight. To achieve this, we recommend:

  • Personalised dietary and exercise analysis and feedback –three days of diet and exercise, completed and analysed before the course starts
  • Sessions on healthy eating, fitness, motivation, reducing problems that prevent lifestyle change, goal setting and effective planning to maintain lifestyle change
  • Activities (if wanted): pilates, resistance work
  • Post-course support by e-mail

Corporate weight-loss courses can be run in the workplace. Please contact CORE to discuss your requirements.
