Fasting may be in vogue, but there’s a new, compelling reason to give it a go: It helps alter the circadian rhythms of cells in the body that play a role in avoiding age-related disease, like dementia, according to researchers at the University of California, Irvine.
In lab studies, daylong fasts can rewire metabolism, making it more efficient. This rewiring actually adjusts gene regulation—a process responsible for a lot of cell activity, including preventing disease. So, while, yes, fasting has been linked with better weight-loss results and body composition, there’s a much greater reason to get on board.
