Women come up with some very novel ideas to prove to themselves they weigh less than they actually do.
According to the diet website Go Lower, many admit to standing on one leg when they hop on the scales in the hope it will reduce the reading by a few pounds, reports the Daily Express.
And more than half confess they take all their clothes off before getting weighed.
Thousands even said they only get on the scales before a meal for fear their undigested dinner would add a couple of extra pounds.
And in desperation to convince themselves they are lighter, almost four in 10 go to the toilet first, while one in 10 admit to breathing in as they step on the scales.
But an astonishing three per cent - which translates to approximately half a million women - wait until a full moon to weigh themselves in the belief this is their lightest time of the month.
The survey quizzed 3,000 women of all ages.
Almost half of women who weigh themselves turn out to be heavier than they thought.
