title: Modifying diet and physical activity to support pregnant women who are overweight or obese.
abstract: OBJECTIVE
  Overweight and obesity represent a significant health burden during pregnancy, placing women and their infants at increased risk of adverse health outcomes. Although there is considerable observational literature describing the effect of gestational weight gain in pregnancy, research efforts have focused on limiting gestational weight gain among pregnant women who are overweight or obese, with limited reporting of clinical outcomes.
  
  
  RESULTS
  The LIMIT randomized trial recruited 2212 pregnant women with a BMI at least 25 kg/m2. Providing an antenatal dietary and lifestyle intervention was associated with significant improvements in maternal diet and physical activity patterns, and a significant reduction in the risk of infants being born with high birth weight.
  
  
  CONCLUSIONS
  The findings of the LIMIT randomized trial provide the first evidence that changes in maternal diet and physical activity during pregnancy can reduce the risk of high infant birth weight among women who are overweight or obese, and from a public health perspective, may represent a significant strategy to tackle the increasing problem of childhood and adulthood obesity.
