Obesity during pregnancy is a major health problem in the United States. In this issue of the JCI, Most et al. fill an important gap in our understanding of energy homeostasis in pregnancy. The researchers measured energy intake, energy expenditure, and body composition in obese pregnant women. They demonstrated that energy intake need not increase in order for obese women to gain the recommended amounts of weight during pregnancy. Additionally, all of the gestational weight gain scenarios (inadequate, recommended, or excess) resulted in similar maternal and fetal perinatal outcomes. This evidence should guide new recommendations on this important topic.
孕期肥胖是美国的一个主要健康问题。在本期 JCI 中，Most 等人填补了我们对孕期能量平衡理解的一个重要空白。研究人员测量了肥胖孕妇的能量摄入、能量消耗和身体成分。他们表明，肥胖女性不必增加能量摄入就能在孕期获得推荐的体重增长。此外，所有的孕期增重情况（不足、推荐、或过多）都导致了相似的母婴围产结局。这一证据应该为这个重要话题提供新的建议。
