This study looks at whether stopping tube feeding for at least 8 hours before a procedure (fasting) or continuing it until right before (not fasting) leads to better recovery in critically ill patients on breathing machines. About 1,072 adults in the ICU will be randomly assigned…

This study looks at how a 24-hour fast changes the way immune cells work and use energy. Researchers will take blood samples from 28 healthy adults before and after fasting to measure changes in immune cell metabolism and function. The goal is to better understand the link betwee…

This study explores what happens to your body's cells and metabolism during a long fast. Researchers will take blood samples from 15 healthy adults before, during, and after a prolonged fast. They will then test how that blood affects breast cancer cells in a lab dish, to see if …

This study looks at how a 36-hour water-only fast changes the immune system in healthy adults aged 20-40. Researchers will measure immune cells and gene activity in blood samples. Only 4 men are being enrolled, so results will be very early and limited.
