Aging: 8 to 9-hour daily eating window may boost brain health

A small Rutgers University pilot clinical trial presented at NUTRITION 2026 found that older women with overweight or obesity who limited eating to an 8- to 9-hour daily window showed greater improvements in spatial planning and problem-solving than those following a standard eating schedule, despite similar weight loss. The study involved 47 women over six months and has not yet been peer reviewed. Researchers and outside experts said the findings are preliminary and that larger, longer-term studies are needed to determine whether time-restricted eating can affect dementia risk or age-related cognitive decline.
