Ruth Gretton
Ruth qualified as a Registered Nurse at the Bath School of Nursing in 1980 before working in the NHS at St Martin’s Hospital in Bath in acute medical care for older people where she was promoted to Ward Sister.
Further qualifications followed with a Diploma in Nursing (Distinction) from the University of London in 1995 and a BSC Hons in Specialist Palliative Care from the University of West of England in 2008.
From 2004 Ruth worked at Dorothy House Hospice near Bath as Ward Sister of the Inpatient Unit until her retirement in 2020 as Director of Patient and Family Services.
Throughout her nursing career, Ruth cared for patients experiencing the life-changing impact of chronic ill health. It, therefore, seemed fitting to her that she came out of retirement to work on the creation of the Combe Grove Metabolic Health Retreat, a proactive way to help people improve personal metabolic health thereby reducing the risk of developing life limiting metabolic diseases.
Dr Campbell Murdoch
Campbell is a GP with a special interest in metabolic health. He works within the NHS as a GP in Somerset and delivers programmes with Preventative Healthcare Group to support people to take control of their health.
Having undertaken over 100,000 patient consultations it became very evident that poor metabolic health is the modern-day challenge, causing health conditions that affect most of the population. This spans type 2 diabetes, prediabetes, dementia, high blood pressure, some cancer, fertility problems, heart disease, musculoskeletal conditions, infection risk and many more. Poor metabolic health can also affect mental health and general physical wellbeing. But it’s a problem that cannot be fixed with more pills. The solutions lie in addressing the root causes. Through doing this the expectation is people can reverse prediabetes and type 2 diabetes, improve blood pressure, lose belly fat, and feel well again.
Campbell also has a background in Sports and Exercise Medicine, Quality Improvement, and Teaching. He is a clinical advisor to the Royal College of General Practitioners and a scientific advisor to the Public Health Collaboration.

Dr Ian Lake
Dr. Ian Lake, a founder member of The Public Health Collaboration (phcuk.org), has spent nearly four decades serving as a doctor in the NHS, primarily as a general practitioner. Diagnosed with LADA Type 1 Diabetes at 36, he initially managed his condition through conventional methods. However, a shift to a very low carbohydrate lifestyle a decade ago led to remarkable improvements in blood glucose control and daily life, reducing the frequency and severity of hypoglycemic episodes. This personal transformation inspired Dr. Lake to support others with Type 1 Diabetes in exploring the benefits of low-carb diets. Dr Ian Lake contributed on developing Combe Grove's Type 1 Diabetes Programme, bringing his insights and commitment to real food lifestyles and metabolic health to support and empower others.

His diagnosis marked a significant turning point for both Giancarlo and Katie, who began exploring recipes that aligned with these dietary changes. Through their journey, they encountered a supportive community of low-carb advocates and connected with Dr David Unwin, a pioneering GP who supports diabetic patients in remission through dietary adjustments. This collaboration led to their bestselling book, The Diabetes Weight-loss Cookbook, written in partnership with Dr. David and Dr. Jen Unwin, and became a foundation for four more books focused on low-carb eating and Type 2 diabetes remission.
Today, with Giancarlo's diabetes in remission and his HbA1c levels within the normal range, the Caldesis are passionate about helping others reclaim their health through lifestyle changes.
