KetoNiFast: Cyclic Enteral Daytime Feeding With Ketogenic Nighttime Fasting
Trial Parameters
Brief Summary
A physiological human nutrition includes circadian feeding and nighttime fasting during sleep. There is increasing evidence, that this natural fasting episode over nighttime majorly contributes to repair processes of the human body. So far, intensive care patients are normally enterally fed continuously, so that there is no circadian nutrition and no nighttime fasting. An enteral nutrition for 12 hours followed by a fasting period of 12 hours supported by exogenous ketone salts potentially improves the reconstitution of ICU patients compared to ICU patients who are continuously enterally fed.
