Does food reward predict changes in weight and body composition during multidisciplinary interventions in adolescents with obesity? Bayesian and frequentist meta‐analyses
Authors' conclusion
Baseline implicit wanting for sweet (high carbohydrate, low protein), but not energy-dense, foods may be more strongly related to prospective changes in lean mass than fat mass during weight loss in adolescents with obesity. Further research is needed to clarify whether low protein intake can account for this effect.
Study context
- Population
- Adolescents with obesity in 6 clinical trials of similar 12-week multidisciplinary interventions
- Participants
- 132 adolescents6 clinical trials
- Outcome
- Associations between baseline explicit and implicit food reward and preference (liking and wanting for foods varying in fat content and sweet taste) and prospective changes in weight and body composition
- Follow-up
- Enrolment to post-intervention

Pooled result
As reported in the abstract
- Greater implicit wanting for sweet foods associated with greater loss of standardised body mass
- p = 0.039, η2p = 0.05
- Greater implicit wanting for sweet foods associated with greater loss of standardised lean mass
- p < 0.001, η2p = 0.13
