Mijatovic J, Louie JCY, Buso MEC, et al. - Women with gestational diabetes (GDM) randomly assigned to a lower carbohydrate diet were compared with those assigned to routine care regarding blood ketone concentration, risk of ketonemia, and pregnancy outcomes. Random assignment was performed of 46 women [age (mean ± SEM): 33.3 ± 0.6 y; prepregnancy BMI: 26.8 ± 0.9 kg/m²] at 28.5 ± 0.4 wk. Analysis revealed no rise in ketones to clinical significance in correlation with an intervention to reduce carbohydrate intake in GDM; this is possibly because the target of 135 g/d was difficult to attain in pregnancy.
