Meal timing shapes the daily rhythms of body clocks in mice

The phase of peripheral clocks was altered by the amount of food and the interval between feeding time points.

• Irregular eating patterns influence the synchronization of peripheral circadian clocks in mammals.
• The amount of food consumed and the timing of meals affect how these clocks adjust.
• Feeding frequency does not impact peripheral clock phases if the intervals between meals remain consistent.
• Separating a late dinner into two half-dinners may help mitigate disruptions in clock synchronization.
