The impact of low-energy total diet replacement with behavioural support for remission of type 2 diabetes on disordered eating (ARIADNE): Protocol for a non-inferiority randomised controlled trial.

INTRODUCTION: The National Health Service (NHS) in England is currently piloting a weight loss programme for remission of newly diagnosed type 2 diabetes (T2D), where participants replace all food with low-energy nutritionally complete formula products for 12 weeks (total diet replacement, TDR) and receive behavioural support. In a clinical trial, this programme led to remission in nearly half the participants. However, this weight loss programme might also worsen disordered eating and prompt eating disorders in susceptible people. We aim to investigate if the TDR programme is non-inferior to standard care in terms of disordered eating in susceptible individuals. METHODS: Fifty six people with newly diagnosed T2D, BMI ≥ 27 kg/m2, and medium to high scores of disordered eating based on the Eating Disorders Examination questionnaire (EDE-Q) will be randomised 1:1 to TDR receiving remote weekly/bi-weekly dietetic support or standard care. Participants will be re-assessed remotely at 1, 3, 4, 6, and 12 months. The primary outcome will be the between-group difference in the score of the EDE-Q. If the sample size can be expanded to 150, we will reduce the non-inferiority boundary. Weight, glycated haemoglobin (HbA1c), impairment from disordered eating, and distress will be secondary outcomes. Using the recorded consultations, we will evaluate the process in observed changes in eating behaviour and disordered eating. CONCLUSIONS: If TDR for T2D remission is deemed non-inferior to standard care, more people may enrol and benefit from T2D remission. If TDR exacerbates disordered eating, screening may reduce unintended harm. TRIAL REGISTRATION: NCT05744232 (ClinicalTrials.gov, prospectively registered).

The effect of messaging on the acceptance of swaps to reduce the energy content of snacks and non-alcoholic drinks ordered in an experimental online workplace canteen: A randomised controlled trial.

Finding effective ways to increase acceptance of lower-energy swaps offered for snacks and non-alcoholic drinks may reduce population energy intake. We examined whether incrementally increasing the tangibility of information accompanying swaps offered increased their acceptance. UK adults (n = 3481) selected a sweet snack, a savoury snack, and a drink in an experimental online canteen after being equally randomised to receive one of four messages when swaps were offered; a control message providing no specific information, a vague calorie message, an exact numeric-calories message or, a physical activity calorie equivalent (PACE). Primary outcomes were the between-group differences in (i) the odds that a sweet, savoury, or drink swap would be accepted and (ii) the energy content for each type of item ordered. Compared with control, the numeric-calories and PACE messages significantly increased the odds of accepting a sweet snack swap. All interventions significantly increased the odds of accepting savoury swaps compared with control. Only the PACE message significantly increased the odds of drink swap acceptance. The numeric-calories and PACE messages significantly reduced the energy content of sweet snacks. All interventions significantly reduced the energy content of savoury snacks. None of the intervention messages significantly reduced the energy content of drinks compared with control. Increasing the tangibility of information provided when offering swaps increased swap acceptance. PACE messaging was the most promising.

Attitudes, challenges and needs about diet and physical activity in endometrial cancer survivors: a qualitative study.

With rates of endometrial cancer survival increasing, there is growing interest about lifestyle behaviours that could improve quality of life and reduce the risk for chronic diseases. This study aimed to explore the attitudes, challenges and needs of endometrial cancer survivors regarding diet and physical activity. Sixteen UK-based endometrial cancer survivors participated in two focus groups (n = 5, n = 3) or individual telephone interviews (n = 8), using a semi-structured interview guide. Data were collectively analysed by two researchers until consensus was reached on a coding structure. Data analysis proceeded until themes were identified. Participants were within 5 years post-cancer treatment with median age and BMI of 57 years and 25.8 kg m-2 respectively. Three themes were identified: (1) defining a healthy lifestyle, (2) factors influencing diet and physical activity and (3) needing to search for information. Results suggest interventions should incorporate recommendations on managing late-treatment effects, and behaviour change techniques for cognitive, practical and social barriers to healthy lifestyle changes. Healthcare professionals are in a vital position to provide or introduce endometrial cancer survivors to in-person behaviour change interventions at the early post-treatment period.
