Abstract Objective To characterise participants who dropped out of the Food4Me Proof-of-Principle study. Design The study was an Internet-based, 6-month, four-arm, randomised controlled trial. control group received generalised dietary and lifestyle recommendations, whereas to three different levels personalised nutrition (PN) advice based on dietary, phenotypic and/or genotypic data, respectively (with either more or less frequent feedback). Setting Seven recruitment sites: UK, Ireland, Netherlands, Germany, Spain, Poland Greece. Subjects Adults aged 18–79 years ( n 1607). Results A total 337 (21 %) during intervention. At baseline, dropouts had higher BMI (0·5 kg/m 2 ; P <0·001). Attrition did not differ significantly between individuals receiving guidelines (Control) those PN. Participants were likely drop (OR; 95 % CI) if they feedback (1·81; 1·36, 2·41; <0·001), female (1·38; 1·06, 1·78; =0·015), than 45 old (2·57; 1·95, 3·39; <0·001) obese (2·25; 1·47, 3·43; in reported interest losing weight (1·53; 1·19, 1·97; skipping meals (1·75; 1·16, 2·65; =0·008), claimed eat healthily frequently (0·62; 0·45, 0·86; =0·003). Conclusions PN but related attrition for interventions. Better strategies are required minimise among younger participating interventions may be unnecessary burden.
