12-hour Time Limited Feeding in Critical Care

This study is being done to assess the feasibility and safety of a time-restricted 12-hour enteral feeding protocol (experimental group) in comparison to a standard-of-care, 24-hour enteral feeding protocol (control group) in critically ill patients. Investigators hope to gain knowledge about how these feeding schedules affect feeding tolerance, blood sugar control, and other factors affecting critically ill adult patients. * Investigators expect that the 12-hour feeding protocol will be tolerated similarly to the 24-hour feeding protocol and will not result in a greater number of adverse events related to feeding. * Investigators expect that the proportion of participants in both groups receiving at least 75% of their estimated nutrition needs will be similar.
