A survey has marked December 29 as the day when people feel most guilty about giving into their indulgences over the last 12 months.
Loan Underwood, a health expert at Fitness TV which conducted the poll, asked a panel of 2,000 adults to pinpoint a moment of maximum embarrassment over their excesses, including eating, drinking and times spent in front of the TV.
More than 40 per cent felt that the day in the middle of the festive season i.e. four days after Christmas and three days before New Year was the 'guiltiest' time of the year.
"This year has been a difficult one for many so Christmas has been a real opportunity for people to let their hair down and indulge," the Telegraph quoted Underwood as saying.
"And with the festive season starting even earlier, the constant invites for post work drinks, parties and treats at home mean exercise routines go out the window.
"This has left people feeling that they have a mountain to climb to get back in shape in 2010, making December 29 the day we feel most guilty about our indulgences.
"Exercise is the perfect way to ditch those feelings of remorse and feel great again," Underwood added.
