“Trying to make healthy choices”: the challenges of the food reintroduction phase of the NHS Low Calorie Diet Programme pilot for type 2 diabetes

Abstract

Background: The food reintroduction phase of the NHS Low Calorie Diet (LCD) programme aims to support service users to reintroduce food gradually back into their diet. Understanding experiences of food reintroduction from a broad and diverse range of service users is critical in helping to improve service delivery and commissioning and equity in care. Methods: This was a co-produced qualitative study underpinned by a realist informed approach, using interviews and photovoice techniques. Service users (n=43) of the NHS LCD Programme were recruited from three delivery models across 21 pilot sites in England. Data were analysed using a thematic approach. Results: The food introduction phase required control and planning that challenged the behaviours of participants. Around a third of participants continued use of Total Diet Replacement products, or considered doing so, for convenience and to maintain calorie control. The coach–service user relationship was important to understanding of session content and translation into behaviour change. Physical activity increased during this phase, which contributed to positive health outcomes. Conclusions: The paper reports insights from the food reintroduction phase of the LCD programme. Key messages include the need for increased frequency of support and the need for tailored and culturally representative education.
