high-fat diet during light followed by low-fat diet during darkness (the mice’s awake/active period) versus a low-fat diet during light followed by a high-fat diet during darkness.
experiment two: no food during light followed by a high-fat diet during darkness versus no food during light followed by a low-fat diet during darkness.
experiment three: no food during light followed by a high-fat diet for the first four hours of darkness (the early awake/active period) and a low-fat diet for the next eight hours versus no food during light, a low-fat diet for eight hours and a high-fat diet for the last four hours of darkness (the late awake/active period).
experiment four: no food
