Scientists Tested an 8-Hour Eating Window and Found a Surprising Brain Benefit

In a pilot trial of 47 older women with overweight or obesity, both calorie-cutting groups lost about 15 pounds over six months.

The group that ate within a shorter daily window of about 8.2 hours did better on spatial planning and problem-solving tests than the comparison group.

They also made fewer memory and learning errors, though the difference was not statistically significant.

Researchers say earlier, time-restricted eating may support brain health beyond weight loss and could inform future dementia-prevention studies.
