Time-Restricted Eating and Cancer: Clinical Outcomes, Mechanisms, and Moderators
Cedars-Sinai Medical Center
Summary
The purpose of this study is to test whether the timing of meals can improve treatment adverse events, influence tumor biology and alter a person's mood and behaviors.
Description
Combining fasting with chemotherapy is known to cause complete tumor regression and long-term survival in animal models. According to the Differential Stress Sensitization (DSS) theory, acute fasting sensitizes tumor cells to the cytotoxic effects of chemotherapy and radiation, while protecting healthy cells by increasing stress resistance. These effects are believed to be largely mediated via the Insulin-like Growth Factor (IGF-1) pathway. However, extended fasting can be challenging for patients and poses undue health risks. A number of alternative intermittent fasting regimens have been pro…
