Design outcomes

Primary

MeasureTime frame
In order to develop a better understanding of fructose metabolism in humans and to serve as supporting knowledge for future fructose studies in hypoxic conditions, blood concentrations of fructose, glucose, insulin, free fatty acids, and triglycerides will be measured. Indirect calorimetry serves to assess changes in substrate oxidation rate following fructose loading.
