Study start date: February 1, 2026

Actual date on which the first participant was enrolled.

This study focuses on understanding how two specific dietary changes might influence the risk of developing cancer. It looks at the effects of increasing dietary fiber and practicing time-restricted eating, either separately or together, to see if they can help reduce cancer risk. People interested in preventing cancer or those at risk might find this study particularly relevant, as it explores simple, everyday changes in eating habits that could potentially lead to healthier outcomes. Participants in the study will follow specific dietary guidelines, which include increasing the amount of fiber in their diets and/or limiting their eating to certain times of the day. Researchers will monitor various health indicators to assess how these dietary changes impact cancer risk. While the study does not list specific outcomes or risks, the goal is to evaluate whether these dietary interventions can be beneficial in lowering the chances of developing cancer. This could offer new insights into simple dietary strategies for cancer prevention.
