Real-World Data of a Group-Based Formula Low Energy Diet Programme in Achieving Type 2 Diabetes Remission and Weight Loss in an Ethnically Diverse Population in the UK: A Service Evaluation

(1) Background: Formula low energy diets (LED) are effective at inducing weight loss and type 2 diabetes (T2DM) remission. However, the effect of LED programmes in ethnic minority groups in the UK is unknown. (2) Methods: A service-evaluation was undertaken of a group-based LED, total diet replacement (TDR) programme in London, UK. The programme included: a 12-week TDR phase, 9-week food reintroduction and a 31-week weight maintenance phase and was delivered by a diabetes multi-disciplinary team. (3) Results: Between November 2018 and March 2020, 216 individuals were referred, 37 commenced the programme, with 29 completing (78%). The majority were of Black British (20%) ethnicity with a mean (SD) age of 50.4 (10.5) years, a body mass index of 34.4 (4.4) kg/m(2) and a T2DM duration of 4.2 (3.6) years. At 12 months, 65.7% achieved T2DM remission, with a mean bodyweight loss of 11.6 (8.9) kg. Completers lost 15.8 (5.3) kg, with 31.4% of participants achieving ≥15 kg weight loss. Quality of life measures showed significant improvements. (4) Conclusions: This service evaluation shows for the first time in the UK that a group-based formula LED programme can be effective in achieving T2DM remission and weight loss in an ethnical diverse population.
