American scientists have found that
dieting actually makes people more likely to be irritable and angry. Aggressive
behavior is provoked by the effort involved in resisting food cravings and
being disciplined about their dietary intake.
When scientists compared the
attitudes of the participants who were on a diet with those who ate what they
wanted, they found that people on diet were quicker to express irritation. David
Gal of Northwestern University and Wendy Liu of the University of California have
found that people who were dieting and who picked up an apple instead of a
chocolate bar were more likely to prefer anger or revenge-themed movies. Scientists
also noted that people on a diet preferred to read more
controlling and demanding public policy
messages than sad messages that appealed to their emotions.
The study has been published in the
Journal of Consumer Research.
