Unfortunately, few weight gain prevention interventions have shown efficacy in this age group. Weight suppression, traditionally defined as the difference between highest lifetime weight and current weight, is a robust predictor of weight gain in college students and individuals with eating disorders but has received limited attention in the context of weight gain prevention programs. Among emerging adults aged 17-20 years (N = 133) participating in a 6 week dissonance-based weight gain prevention program (Project Health), the current study examined if: 1) weight suppression predicted change in BMI, percent body fat, and onset of overweight and obesity at 6 weeks (post-intervention) and 6 month follow-up, and 2) weight suppression was related to attentional bias, palatability ratings, and monetary valuation of high calorie foods at baseline. Exploratory analyses examined potential moderators of the relation of weight suppression to change in percent body fat, and the relations of highest lifetime weight and current weight (i.e., the components of weight suppression) to change in percent body fat. Participants reported on their weight history and demographic characteristics at baseline. Height, weight, and percent body fat were measured in-person at baseline, 6 weeks, and 6 months. Higher weight suppression was cross-sectionally associated with lower percent body fat at baseline, (r(131) = -.19, p = .03) and 6 months (r(131) = -.19, p = .04) but did not predict change in percent body fat or BMI or onset of overweight/obesity. Weight suppression was not related at baseline to attentional bias, palatability ratings, or monetary valuation of high calorie foods. No moderation effects of weight suppression on weight change were observed. Greater highest lifetime weight (p = .006, sr2 = .11) and greater baseline weight (p = .007, sr2 = .29) (i.e., the two components of weight suppression) each predicted larger decreases in percent body fat between baseline and 6 weeks, and these effects held from baseline to 6 months. Contrary to hypotheses, this study found no evidence that weight suppression predicted 6 month change in BMI, percent body fat, or onset of overweight/obesity among emerging adults enrolled in a weight gain prevention program. It is possible that the intervention buffered against the typical effects of weight suppression, and/or that a longer follow-up period is needed to see effects of weight suppression on outcomes in the context of a weight gain prevention program. Additional directions for future research are discussed.
