How long does it take for your body to become accustomed eating breakfast?

It can take anywhere from a few days to a few weeks to become accustomed to eating breakfast regularly. Initially, you might feel full or uncomfortable after eating breakfast, but this feeling should subside over time as your body adjusts to the new routine. To make the transition easier, start with small, light breakfasts and gradually increase the size and complexity of your meals as your body becomes accustomed to them.
