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

IntroductionThe 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.MethodsThis 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.ResultsA total of 660 members enrolled and retention was 41% at 12 months. The majority were female (73.2%), 58.9% were of White ethnicity, with a mean (SD) age of 47.5 years (10.1), and a body mass index of 35.0 kg/m2 (5.7). Data were available for 82 members at 12‐month. At 12‐month, members mean actual and percentage weight loss was −9.0 kg (7.0; p < 0.001) and −9.2% (6.7, p < 0.001) respectively and waist circumference reduced by −10.3 cm (10.7 p < 0.001), with 45.1% of members achieving ≥10% weight loss. Glycated hemoglobin was significantly improved at 6 months in people living with T2D (−11 mmol/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).ConclusionOur 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.
