According to a survey, November 10 is the day when majority of Brit women start dieting to get in shape for the annual Christmas party in the office.
The poll of 3,000 women revealed that six out of 10 women choose November 10 as the day to begin dieting in a bid to fit into their glitzy outfit.
While the average dieter aims to lose 10lb, but one in 10 will skip the odd meal in a bid to reach their target.
Fourteen per cent buy their party outfit in a size too small thinking they will fit into it by the time the big event arrives.
But more than half of these women will have to buy an emergency outfit after failing to lose the weight in time.
However, much to their agony, 21 per cent of women put all the weight they lose back on by the New Year.
A spokesman for British Lion eggs, which carried out the research, advised women to be careful when trying to diet.
"Simply cutting out food won't work. The best way to lose weight is to eat sensibly and have three balanced meals a day, particularly breakfast," the Daily Express quoted him as saying.
