ClinConnect Summary

This clinical trial is studying how high-intensity exercise affects energy use and thinking abilities in healthy adults during a fasting period of 24 to 34 hours. Researchers want to see if exercising while not eating changes how the body metabolizes energy and how well people can think. Participants will go through different sessions where they either exercise or rest while fasting, and their body responses and cognitive performance will be measured afterward.

To be eligible for this study, participants should be between 18 and 40 years old, have a healthy weight, and have not experienced significant changes in their weight or sleeping patterns recently. They must also be able to eat all the study-provided foods. Those with chronic health conditions, pregnant or breastfeeding individuals, and those using certain medications or supplements are not eligible. Participants can expect to provide some information about their health, engage in physical activities, and help researchers gain insights into how fasting and exercise interact.
