Women are about twice as likely as men to suffer from 'carb guilt', even though they were more likely to be a healthy weight, according to a survey of 3,000 people.
One in ten women said they felt guilty all the time about the amount of carbohydrates they ate while about a quarter said they would avoid them in the week to allow themselves to indulge at the weekend.
Jane Ogden, a professor in health psychology at the University of Surrey who helped design the research, said that people were irrationally demonising carbohydrates.
The survey, conducted for a weight-loss brand, found that most of those questioned were unaware of how much carbohydrate they should be eating.
The recommended daily allowance is 250g - around half of a person's daily calories - but when asked what that might amount to in food, most people significantly underestimated it, 'The Times' reported.
Instead of trying to cut out carbohydrates, Ogden said that the focus should be on avoiding "bad carbs" from added sugar, and trying to include foods with healthy complex carbohydrates, such as whole grains, beans, fruits and vegetables.
