Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
