About Us
About Prevent Diabetes
Prevent Diabetes was founded in 2026 by husband and wife team Cara and Oliver, to make personalised dietary support easier to get for people diagnosed with prediabetes. We also support adults with a BMI over 26 who want help with weight management. We founded Prevent Diabetes to offer personalised, one to one dietary guidance for people who want it, online and at their own pace.
We understand that knowing where to start after a prediabetes diagnosis can feel overwhelming. Our online service provides personalised dietary guidance in a convenient and accessible way, helping you identify practical changes that fit your lifestyle and support your long term health.
Once we receive your completed online questionnaire, we aim to deliver your personalised assessment within 10 working days. Every assessment is reviewed personally by Cara Sommariva-Nagle, a Registered Dietitian, ensuring that the advice is tailored to your individual circumstances.
Whilst Cara brings her clinical expertise and healthcare experience, Oliver brings his experience in project delivery and operational management. Together, we combine clinical knowledge with a structured, practical approach to running Prevent Diabetes, with the aim of making personalised prediabetes support accessible, professional and straightforward to use.
