Scientists Tested an 8-Hour Eating Window and Found a Surprising Brain Benefit
SciTechDaily • • health
Key Points:
- A small clinical trial found that limiting daily eating to an 8-9 hour window may improve cognitive functions such as spatial planning and problem-solving beyond the benefits of weight loss alone in older women with overweight or obesity.
- Participants who followed the shorter eating window lost a similar amount of weight as those eating over 12 hours but showed greater cognitive improvements after six months.
- The study suggests that stopping food intake at least four hours before sleep and restricting eating duration could help reduce aging-related cognitive decline.
- Researchers caution that larger trials are needed to confirm these findings and plan to investigate underlying biological mechanisms involving circadian rhythms and metabolic health.
- The results were presented at the American Society for Nutrition’s NUTRITION 2026 annual meeting.
