title: A "small-changes" workplace weight loss and maintenance program: examination of weight and health outcomes.
abstract: OBJECTIVE
  To compare the effect of "small-changes" and "usual care" workplace interventions on weight loss and to investigate the effect of small changes with or without maintenance on weight and health outcomes.
  
  
  METHODS
  Overweight/obese employees at two New Zealand worksites received a 12-month usual-care intervention (n = 53), followed by a 12-month small-changes intervention (n = 102). Small changes comprised a 12-week component, followed by 9 months of maintenance, implemented at only one worksite. Magnitudes of effects were assessed via a threshold of -5% (weight loss) and standardization (health outcomes).
  
  
  RESULTS
  Small changes showed beneficial weight loss relative to usual care in both worksites. For small-changes interventions, worksites reduced weight (12 weeks) and maintained lost weight (12 months). One in every three participants lost 5% or more weight. Some improvements in health outcomes were shown.
  
  
  CONCLUSIONS
  Regardless of maintenance, the small-changes intervention was successful in sustaining weight loss.
