How effective are diet, exercise, or both for weight reduction in women after childbirth?
The available data were insufficient to infer important risks or other potential benefits for the mother or infant. Methodological shortcomings of some trials, especially the small sample size, the small number of studies reviewed for each outcome, and the diversity in the nature, duration and frequency of the interventions require caution in applying these encouraging results.
Weight retention after pregnancy may contribute to obesity. It is known that diet and exercise are recommended components of any weight loss programme in the general population. However, strategies to achieve healthy body weight among postpartum women have not been adequately evaluated.
