If you're one of the many people who can't say no to a late night snack, It could be down to the time you go to bed.
A study has revealed that those of us who put the head down later than 11 PM consume on average 220 calories more than those who retire early.
This is according to data collected by fitness wristband makers Jawbone UP - a tool that monitors exercise & sleep and also allows users to input food and alcohol consumed.
According to the data, those who go to bed after 11 PM will more likely binge on junk food and alcohol, whereas early birds tend to eat healthier foods on the whole.
Jawbone data scientist Kristin Aschbacher wrote:
"Early birds tended to eat healthier foods on the whole.
"This builds on our previous findings that people log more meals high in fats and sugars late in the evening.
"We hope this paints a picture of what a good night’s sleep might do."
So if you want to lose a few pounds go to bed earlier.
