04 Sep 2018 --- Mice lacking the biological clocks thought to be necessary for a healthy metabolism can still be protected against obesity and metabolic diseases by having their daily access to food restricted to a 10-hour window, scientists at the Salk Institute have found. The research, which appeared in the journal Cell Metabolism, suggests that the health problems associated with disruptions to animals' 24-hour rhythms of activity and rest – which in humans is linked to eating for most of the day or doing shift work – can be corrected by eating all calories within a 10-hour window.
