Adherence
Formal, structured interventions aimed at preventing weight gain in normal-weight adults have minimal effect and are not recommended.
If you are already at a normal weight, formal weight-loss programs are not recommended as they offer minimal benefit (less than 1 kg). Focus on maintaining your current healthy lifestyle rather than seeking out structured prevention programs.
