Time-restricted feeding, where eating occurs within an 8 to 12-hour window per 24-hour cycle, may promote longevity independent of weight loss.

“if we can segment those out um obviously in humans it's hard to know if a given treatment or experiment is extending life because you don't really know how long people would live anyway yeah right whereas with mice you have some sense of when the mortality was likely to occur so what can we say about time restricted feeding and longevity in terms of biomarkers or in terms of any other indication that people who start and stop their feeding window at a consistent time somewhere between 8 and 12 hours per 24 hour cycle are tilting the scales towards living longer as opposed to living shorter”
