Do people with type 2 diabetes find continuous and intermittent low-energy diets for weight loss and diabetes remission acceptable?

BackgroundThe Manchester Intermittent versus Daily Diet App Study (MIDDAS) tested the feasibility and potential efficacy of two remotely delivered low-energy diet (LED) programmes (800 kcal/day) to support weight loss and remission of type 2 diabetes: continuous [CLED] (8 weeks of daily LED) and intermittent [ILED] (2 days of LED/week for 28 weeks). Understanding participant experiences can help us to understand the acceptability of LED programmes to people with type 2 diabetes, informing future programme development and implementation.MethodsTwenty participants (10 CLED; 10 ILED) took part in interviews conducted at the end of the active weight loss phase (CLED week 12, ILED week 28). Interviews were transcribed and analysed thematically using the template analysis approach, with an a priori focus on acceptability. Four themes are presented: prospective acceptability, intervention coherence and perceived effectiveness, opportunity costs and self-efficacy.ResultsBoth remotely supported CLED and ILED interventions appeared acceptable to participants. CLED participants found the rapid initial weight loss phase comparatively easy and highly motivating but expressed more concerns around weight maintenance. ILED participants found the more gradual weight loss initially frustrating but expressed greater confidence in their longer-term adherence. The importance of continued individualised support from healthcare professionals was emphasised, and evidence of weight loss and improvement in other medical markers through monitoring via the mobile phone app was useful.ConclusionDifferent approaches to remotely delivered LEDs appear acceptable; therefore asking patients which approach may be more acceptable to them may be a useful way to offer individualised and tailored support. We interviewed people with type 2 diabetes (T2D) who had taken part in either a continuous low-energy diet (CLED) or an intermittent low-energy diet (ILED). Both diets appeared to be acceptable. Discussing different (CLED/ILED) approaches and their potential benefits and challenges may better prepare T2D patients for a LED. image We interviewed people with type 2 diabetes (T2D) who had taken part in a randomised controlled trial comparing a continuous low-energy diet (CLED) and an intermittent low-energy diet (ILED) about how acceptable they found the interventions. We found that both diets appear to be acceptable to people with T2D. Discussing different (CLED/ILED) approaches and their potential benefits and challenges may better prepare patients for a LED, although further research to test the efficacy of ILED for diabetes remission is still required.
