GRAPHICAL ABSTRACTExercise decreases abdominal fat mass, especially at high intensity. This outcome is not causally associated with fat burning, but better explained by carbon and nitrogen redistribution. Since abdominal fat tissue constantly releases fatty acids into circulation under post-absorptive condition with natural cell deaths, exercise diverts more post-meal carbon and nitrogen to muscle for energy repletion and cell regeneration after phagocytosis and stem cell homing. This in turn leads to concurrent fat mass loss and muscle mass gain. Respiratory ventilation during high-intensity aerobic exercise amplifies the competition for post-meal carbon and nitrogen against adipose tissues.

ObjectivesTo examine the patterns of fat mass gain in pregnancy and fat loss in the early postpartum period relative to women’s pre-pregnancy body mass index (BMI) and by adherence to Institute of Medicine’s gestational weight gain (GWG) recommendations.DesignProspective cohort study with three to four study visits.SettingThis study is a part of the prospective longitudinal birth cohort, ‘The Alberta Pregnancy Outcomes and Nutrition Study’ (APrON) that recruited pregnant women from the cities of Edmonton and Calgary in Alberta.Participants1820 pregnant women were recruited and followed through their pregnancy and at 3 months postpartum.Outcome measuresBody weight and skinfold thicknesses were measured during pregnancy and early postpartum in women. Body density was calculated from sum of skinfold thickness (biceps, triceps, subscapula and suprailiac), and total fat mass accretion during pregnancy was calculated using Van Raaij’s equations and at postpartum using Siri’s equation. Differences in total fat mass gain, fat mass loss and fat retention according to pre-pregnancy BMI categories and GWG categories were tested using two-way analysis of variance and post hoc comparisons.ResultsMost women (64%) had a normal pre-pregnancy BMI, and overall 49% women exceeded the GWG recommendations. Obese women gained significantly less total fat mass, had lower fat mass loss and had lower postpartum fat retention than normal-weight women (p<0.05). Women with excessive GWG gained higher total fat mass and had higher postpartum fat mass retention (p<0.03) than women who met the GWG recommendations. Total GWG was positively correlated with total fat gain (r=0.61, p<0.01) and total fat retention (r=0.31, p<0.05).ConclusionExcessive GWG is the significant risk factor for higher fat mass accretion during pregnancy and higher postpartum fat retention, irrespective of pre-pregnancy BMI.
