A cross-sectional analysis of emotional and binge eating in UK adults enrolled on the NHS Low-Calorie Diet Pilot for Type 2 Diabetes

Aims: This study presents data gathered as part of the Re:Mission evaluation of the NHS low-calorie diet programme pilot for Type 2 Diabetes, to address two research questions: 1) What is the presence and severity of emotional and binge eating within this population? 2) Are demographic and health factors associated with the presence of binge eating or the severity of emotional eating?
Methods: An online survey gathered data from n = 580 individuals who were enrolled on the programme but had not yet begun total diet replacement. The survey assessed emotional eating (TFEQ-R21), potential Binge Eating Disorder diagnosis (BEDS-7), wellbeing (Short Warwick-Edinburgh Mental Wellbeing Scale), quality of life (EQ-5D-5L), frequency of weight cycling and demographic factors (collected via NHS England programme monitoring). Descriptive statistics and regression analyses were used to address the research questions.
Results: The mean emotional eating score from the TFEQ-R21 was 2.58 (0.96), and the presence of potential Binge Eating Disorder diagnosis was demonstrated in 26.0% of the sample. Regression analyses suggested that being female and engaging in more frequent weight cycling was associated with higher emotional eating and greater likelihood of binge eating. Lower wellbeing and lower quality of life were associated with emotional and binge eating, respectively.
Conclusions: Rates of emotional and binge eating in the NHS low-calorie diet pilot sample are higher than in the general public, and in other similar samples. Consideration should be given to screening for emotional and disordered eating, and for additional tailored support and monitoring for such individuals.
