Restricted eating hours may reduce cognitive decline in older age, researchers find

The News

A preliminary study suggests that restricting eating to a nine-hour window and avoiding food four hours before bed may improve cognitive function in older women with overweight or obesity. The pilot study found hints of improvement in mental skills among those who followed the restricted schedule. The findings indicate a simple dietary intervention that could help reduce cognitive decline in older age. Further research is needed to confirm these results.
