5. Study Description

Brief Summary
In the present study, the investigators will assess the impact of two different feeding patterns (continuous vs intermittent) on insulin sensitivity and muscle mass following bedrest.
Detailed Description
In the present study, the investigators will assess the impact of two different feeding patterns on insulin sensitivity and muscle mass following bedrest. Healthy, young males will be fed in a continuous (no breaks in food supply) or intermittent (in boluses throughout the day) manner.
