Mr Dafydd Wilson-Evans

Obesity Specialist Dietitian

I am an Obesity Specialist Dietitian with over 10 years' experience. My specialist interest in weight management started early in my career as a dietitian. I have shaped my career supporting patients within the field of obesity, providing effective nutritional interventions to promote sustained weight loss, but also improve weight-related diseases such as type 2 diabetes. I have gained extensive experience within the field of obesity which has led to me expanding my practice within the speciality of Bariatric Surgery and becoming a Bariatric Dietetic Practitioner.

My intervention involves tailoring nutritional plans that work for the individual, avoiding a ‘one-size-fits-all’ approach. As a dietitian, I provide evidence-based nutritional intervention and steer patients away from ‘fad-diets’. I am passionate about supporting patients to achieve the best possible outcome, ensuring that the patient achieves their aims and optimises their nutritional status.

As well as nutritional intervention, I believe in a multi-professional approach to weight management which may involve surgical, medical, psychological and/or exercise treatments. I aim to provide patients with knowledge and skills that will assist them life-long, promoting physical, psychological and nutritional wellness.

I was awarded a prestigious NIHR research grant to undertake clinical research within the field of bariatric surgery. The research investigated the long term management of vitamin and mineral provision within a postoperative bariatric surgery population.

I have been involved in developing local policy and guidelines relating to weight management and bariatric surgery to ensure the provision of exceptional patient care.
