Primary Outcome Measures :
  1. Total daily energy expenditure (Measured using the doubly labeled water technique) [ Time Frame: Change from baseline ]
    Measured using the doubly labeled water technique


Secondary Outcome Measures :
  1. Peak fat oxidation (Measured during incremental submaximal exercise) [ Time Frame: Change from baseline ]
    Measured during incremental submaximal exercise


Other Outcome Measures:
  1. Energy intake (Measured using selfreported and supervised food logs) [ Time Frame: Change from baseline ]
    Measured using selfreported and supervised food logs

  2. Body composition [ Time Frame: Change from baseline ]
    Measured from isotope dilution

  3. Energy Balance (Discrepancy between energy expenditure and intake or changes in body composition) [ Time Frame: Change from baseline ]
    Discrepancy between energy expenditure and intake or changes in body composition

  4. Cardiac Stress [ Time Frame: Change from baseline ]

Biospecimen Retention:   Samples Without DNA
Urine samples, muscle and subcutaneous adipose tissue biopsies and venous blood samples.
