A new report suggests that limiting food intake to a nine-hour period each day could help protect against dementia, adding to a growing body of research into how eating patterns and timing affect long-term brain health. The claim reflects wider scientific interest in time-restricted eating, a form of intermittent fasting that confines meals to a set daily window, as a potential low-cost way to reduce the risk of cognitive decline.

The article itself, as provided, does not include the underlying study details, methodology or expert commentary that would typically accompany such a claim on the Daily Mail's health pages. As with other intermittent fasting research, any benefits for dementia risk would likely need to be weighed against factors such as age, existing health conditions and the practicality of maintaining such an eating schedule long term.
