New research out of Cornell University finds that most people lose weight on weekdays, but pack on the pounds over the weekend, when they are not working and have more time to go out and eat, Newsmax Health reports.  

For the study, Dr. Brian Wansink, the lead researcher tracked weekly weight fluctuations in 80 people, ranging in age from 25 to 62 years old, who were asked to weigh themselves after waking up each day over a period of time lasting up to 10 months.

The results consistently showed most people weighed more after weekends (Sunday and Monday) and lost weight during the weekdays — reaching the lowest levels on Friday.
