“More research on humans was needed to understand the causes of these findings, but everything seems to indicate that sleep schedules affect our ability to metabolize food,” said Dora Romaguera, the other study author. . “Animal experiments have shown that the time of food consumption has” profound consequences for food metabolism and health. “
