Nutritional Therapy Cardiff

Cardiff NutritionistHello, I’m Stefan, a qualified nutritional therapist and wellness coach based in Penarth near Cardiff, south Wales. I help people with a range of health issues take back control of their wellbeing by changing their diet. If you’re fed up of digestive issues, low energy and fatigue, aches and pains, struggles with weight loss, skin issues, or confusion about which diet is best for you, I’m here to help. Although your current situation may be getting your down, the good news is that small changes to your diet have the potential to show big results in your wellbeing. Coaching sessions are available in-person at my practice near Cardiff or online via video calls. Contact me for a free, no-obligation discovery call.

Naturopathic Nutrition

As a naturopathic nutritionist, my approach to nutritional therapy combines the latest science of nutrition with the art of naturopathy. Naturopathy assumes that the body is constantly striving to be healthy and that creating the right environment will allow the body to heal. Using the latest information from the field of nutrition and wisdom from traditional healing approaches (eg naturopathic techniques), I will guide and support you with a personalised nutrition plan.

ABOUT ME – I became interested in nutrition back in 2003, when I was experiencing blood sugar slumps. I began reading about the problem and discovered that my diet was all wrong! Soon I started experimenting with a low GI diet and within a matter of days my blood sugar stabilised and my energy improved as did my concentration.

From that moment I was hooked on nutrition and in 2007 I started my nutrition practitioner course in London, qualifying three years later as a naturopathic nutritionist. In 2010 I undertook an advanced diploma in nutritional healing and the following year I started my nutritional therapy practice. Since then, I’ve helped clients with a variety of problems, including digestive disorders, fertility issues, skin complaints and fatigue, just to name a few. If you’re ready to make some changes in your life and taking charge of your health, contact me for a free discovery consultation to see how nutrition coaching could help.

Nutrition Consultations

Prior to your first appointment, I will ask you to complete an online questionnaire to take some basic details and help establish what you would like to work on.

At your first session, we will talk about your situation in a more detail and I will take a case history. We will then discuss your expectations from the nutritional therapy, your level of motivation and and any particular challenges you may face.

Based on these details, we will formulate an initial nutrition plan which includes foods to include, those to reduce or exclude and suggestions for meal plans. I will also look at your current ability and motivations to make changes to your diet, and I will advise a plan that suits your needs.

If you choose one of my nutrition packages, you will also benefit from email contact between appointments, providing extra support and guidance.

How Many Appointments Will I Need?

Most of my clients will have had their health complaints for some time, so we need to recognise that it may take a little time to reverse the problem. I also suggest clients make gradual changes to their diet to give them a realistic chance of implementing dietary changes and to avoid possible side effects of sudden diet changes.
With this in mind, I recommend a minimum of three appointments for most clients. More complex problems may require five or more appointments. Please see my packages (below) for details.

Natural Weight Loss Cardiff – With A Difference

Anyone who has tried to lose weight will be aware of the challenges. Even with all the right dietary information and nutrition plans, cravings, limiting beliefs and attitude can easily derail the best laid plans.

As a qualified EFT practitioner, I am able to bring a mind-body approach to your weight loss journey, ensuring you have the best chance of success. By teaching your the basics of EFT tapping, I can show you how to banish those pesky craving, release negative thoughts and create a positive mindset for success. EFT can also be effective i dealing with emotional eating, a common issue with weight loss.
