Dieting stressful and makes people irritable and angry

London: The next time you plan to go on a diet to shed the flab, just give a second thought, for a new study says that dieting is stressful and can make people feel irritable and angry.

Researchers have found that the effort involved in exerting self-control over eating can lead to an aggressive frame of my mind — and even a preference for violent films, `The Daily Telegraph` reported.

They have based their findings on an analysis of a set of three experiments.

In one experiment, people who choose an apple instead of a chocolate bar were more likely to choose movies with anger and revenge themes than milder movies.

In another experiment, participants who exerted financial restraint by choosing a gift certificate for groceries over one for a spa service showed more interest in looking at angry faces rather than at fearful ones.
