- Studies in mice and humans have shown that limiting food intake to the active cycle — when an individual is most active and alert — has various health benefits, including weight loss and improved blood sugar control.
- Now, a new mouse study has shown that restricting feeding to the resting period greatly improved endurance in running tests.
- This effect was surprising and unexpected, as feeding during the resting period is typically considered to be detrimental to health.
- While the findings are intriguing, further studies are needed to understand how they translate to human physiology and athletic performance.
Almost all living things, ranging from bacteria to plants to people, have physical, mental and behavioral rhythms called circadian rhythms, which follow a roughly 24-hour cycle.
Circadian rhythms are driven by
These biological clocks are coordinated by a master clock in the brain called the
Although the body has its own circadian rhythms, these rhythms may be affected by environmental stimuli. The brain’s “master clock,” the SCN, is regulated by
More recently, researchers discovered that
This led to many studies on the effects of time-restricted feeding (in animals) and time-restricted eating (in humans), where daily food intake is limited to a window of 6–12 hours.
