Review Meta AnalysisImproving diet and physical activity to reduce population prevalence of overweight and obesity: an overview of current evidence.
The aim of this study is to provide an overview of interventions to reduce or prevent overweight or obesity and improve diet or physical activity. ⋯ Various individually targeted interventions were shown to reduce body weight, although effect sizes were typically modest, and the durability of effects has been questioned. New approaches to evaluating population-based interventions, such as taxes and regulation, are recommended. Future research modelling the long-term effects of interventions across the lifespan would also be beneficial.
