Brief Summary
This study will compare two approaches to the measurement of fatty acid oxidation (ketone body flux and ketone body concentration) and determine which method demonstrates superior sensitivity and variability in the detection of moderate increases in ketogenesis rates.

Outcome Measures
Primary Outcomes (1)
Effects of increase in serum free fatty acid levels on ketogenesis as measured using a isotopic tracer and serum ketone body concentration in healthy lean subjects
5 hours
Secondary Outcomes (1)
Effects of increase in serum free fatty acid levels on ketogenesis as measured using a isotopic tracer and serum ketone body concentration in obese subjects
5 hours

EXPERIMENTALBiomarker evaluation
Interventions
A stable isotope tracer (13-C(4)-BHB), a commercially available lipid emulsion, and heparin will be administered intravenously. Ketone body concentrations will be measured before beginning the infusion, at approx. 135 minutes, and at approx. 255 minutes.
