Real-world data of a digitally enabled, time-restricted eating weight management program in public sector workers living with overweight and obesity in the United Kingdom: A service evaluation of the Roczen program.

Abstract

The health of the United Kingdom workforce is key; approximately 186 million days are lost to sickness each year. Obesity and type 2 diabetes (T2D) remain major global health challenges. The aim of this retrospective service evaluation was to assess the impact of a digitally enabled, time-restricted eating (TRE) intervention (Roczen Program, Reset Health Ltd) on weight and other health-related outcomes. This service evaluation was conducted in people living with overweight/obesity, with 89% referred from public sector employers. Participants were placed on a TRE, low-carbohydrate, moderate protein plan delivered by clinicians and mentors with regular follow up, dietary guidance, goal setting, feedback, and social support. A total of 660 members enrolled and retention was 41% at 12months. The majority were female (73.2%), 58.9% were of White ethnicity, with a mean (SD) age of 47.5years (10.1), and a body mass index of 35.0kg/m2 (5.7). Data were available for 82 members at 12-month. At 12-month, members mean actual and percentage weight loss was -9.0kg (7.0; p<0.001) and -9.2% (6.7, p<0.001) respectively and waist circumference reduced by -10.3cm (10.7 p<0.001), with 45.1% of members achieving ≥10% weight loss. Glycated hemoglobin was significantly improved at 6months in people living with T2D (-11mmol/mol [5.7] p=0.012). Binge eating score significantly reduced (-4.4 [7.0] p=0.006), despite cognitive restraint increasing (0.37 [0.6] p=0.006). Our service evaluation showed that the Roczen program led to clinically meaningful improvements in body weight, health-related outcomes and eating behaviors that were sustained at 12-month.
