The weekends were made late brunches, midnight suppers and 'lunch' at 5pm. But, it transpires, your leisurely approach to Saturday and Sunday eating could be doing you harm. 
In a 2015 study published in the journal Cell Metabolism, researchers found that changing the time and frequency of your eating routine can lead to your body clock getting out of whack – with potentially serious health consequences.
So, what is metabolic jet lag?
According to their findings, the average time people ate breakfast on weekdays was an hour after waking up, or at approximately 9.21am. But by Saturday and Sunday, the same people delayed their first meal to about 10.26am.
But the study red-flagged another one of our bad habits - eating for longer periods of time. People start eating two or three hours later. Then they continue eating until midnight or 1am, because they typically stay up longer on a Friday or Saturday night.
And apparently, 'treat yo' self' isn't a good excuse - because our bodies have become used to our weekday schedule.
Before we had electricity, before everybody was going to work Monday through Friday, taking the weekend off, there was no difference between a Monday and a Sunday. The waking and sleeping times were primarily governed by sunset and sunrise times.
Which means that waiting to eat until brunch is literally messing up your body clock.
And what are the potential repercussions?
So what are the repercussions for us Eggs Benedict-addicts? Mouse studies suggest that metabolic jet lag could lead to a combination of health issues like diabetes, obesity, and high blood sugar.
But don't ditch your weekend waffle-eating ritual just yet.
Restricting yourself to the same 12-hour eating window (e.g. 8am to 8pm) every day of the week - can help you avoid metabolic jet lag altogether.
Okay. Meaning I should eat in which windows?
In the study, people who reduced their daily eating duration from 14 hours to 10 to 12 hours also decreased their calorie consumption by 21 percent — without purposefully trying to cut back. There are foods which are only consumed at preferred times.
So if you limit your feeding window, those time-sensitive foods and drinks — think coffee and cocktails — that you would normally consume at a certain time of day may be naturally eliminated, thereby reducing your calorie intake.
