Abstract

Summary: Diet and exercise are two of the commonest strategies to reduce weight. Whether a diet‐plus‐exercise intervention is more effective for weight loss than a diet‐only intervention in the long‐term has not been conclusively established. The objective of this study was to systemically review the effect of diet‐plus‐exercise interventions vs. diet‐only interventions on both long‐term and short‐term weight loss. Studies were retrieved by searching MEDLINE and Cochrane Library (1966 – June 2008). Studies were included if they were randomized controlled trials comparing the effect of diet‐plus‐exercise interventions vs. diet‐only interventions on weight loss for a minimum of 6 months among obese or overweight adults. Eighteen studies met our inclusion criteria. Data were independently extracted by two investigators using a standardized protocol. We found that the overall standardized mean differences between diet‐plus‐exercise interventions and diet‐only interventions at the end of follow‐up were −0.25 (95% confidence interval [CI]−0.36 to −0.14), with a P‐value for heterogeneity of 0.4. Because there were two outcome measurements, weight (kg) and body mass index (kg m−2), we also stratified the results by weight and body mass index outcome. The pooled weight loss was 1.14 kg (95% CI 0.21 to 2.07) or 0.50 kg m−2 (95% CI 0.21 to 0.79) greater for the diet‐plus‐exercise group than the diet‐only group. We did not detect significant heterogeneity in either stratum. Even in studies lasting 2 years or longer, diet‐plus‐exercise interventions provided significantly greater weight loss than diet‐only interventions. In summary, a combined diet‐plus‐exercise programme provided greater long‐term weight loss than a diet‐only programme. However, both diet‐only and diet‐plus‐exercise programmes are associated with partial weight regain, and future studies should explore better strategies to limit weight regain and achieve greater long‐term weight loss.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
