Brief Summary:
The purpose of this study is to measure energy intake and energy expenditure during and after pregnancy. The investigators hypothesize that obese pregnant women with weight gain above the IOM guidelines, 'High Gainers', will have increased energy intake but no evidence for changes in energy expenditure after adjustment for the weight gained when compared to women with appropriate gestational weight gain, 'Normal Gainers'. Additionally, the investigators will measure the babies born to the pregnant women enrolled in MomEE at one time point before 10 days of life.

Primary Outcome Measures :
  1. Energy intake [ Time Frame: 18 months (pregnancy to 12 months postpartum) ]
  2. Free living energy expenditure and sleeping metabolic rate [ Time Frame: 18 months (pregnancy to 12 months postpartum) ]

Secondary Outcome Measures :
  1. Measurement of changes in physical activity [ Time Frame: 18 months (pregnancy to 12 months postpartum) ]
  2. Measurement of changes in substrate oxidation [ Time Frame: 18 months (pregnancy to 12 months postpartum) ]
  3. Determinants of energy intake including fasting concentrations of leptin, total ghrelin, peptide YY, cholecystokinin [ Time Frame: 18 months (pregnancy to 12 months postpartum) ]
  4. Determinants of energy expenditure including urinary epinephrine and norepinephrine, fasting concentrations of T3, T4, and TSH [ Time Frame: 18 months (pregnancy to 12 months postpartum) ]

Biospecimen Retention:   Samples Without DNA
Placenta, Cord Blood, fasting Urine, fasting Maternal plasma and serum (during pregnancy and postpartum).
