The study suggested that when women know the food is not bad for them, they could find it less tasty as their expectation of pleasure is lowered beforehand. In the study, the researchers split 40 women into two equal groups, one of which was shown healthy living magazines featuring images of people looking fit and slender. The other group looked at magazines whose pictures did not relate to wellbeing.
When all 40 women were given a chocolate bar afterwards and asked to rate their enjoyment of it, those who had read the healthy living magazine said they liked the sweets 16 percent more than those who did not.
Lead researcher Kelly Goldsmith, of the Kellogg School of Management at Northwestern University in Chicago, said the findings showed that experiencing the emotion of guilt can increase pleasure.
“If you advertise your product as being guilt-free, what it could implicitly do is lower taste perception by lowering the expectation of pleasure. If you take the guilt out of it, people might not expect it to be as good,” the Telegraph quoted Goldsmith as telling the Daily Mail. “Let people benefit from the intrigue and pleasure and enjoy their experience more,” she said.
