London, March 2 (IANS): Crash diet is considered to be unhealthy in the long run. Followers of crash diet not only gain the weight they have lost when they return to regular diet, a survey reveals they also lose friends.

The research released by Nakd Wholefoods has found just how irritating people find their friends when they diet, with a third of them deliberately avoiding those they know to be dieting and a quarter even trying to sabotage their friends’ bids to lose weight, reports femalefirst.co.uk.

"I'm surprised that so many people are avoiding their friends who crash diet, our research shows that we're happiest when we're not on a diet so people shouldn't feel pressure to crash diet this January - healthy options for snacking alone have become so widely available, and taste great too, so you don’t have to compromise," said Marina Love, marketing director at Nakd Wholefoods.

The research reveals that two-thirds of the friends, colleagues and partners of dieters find them irritating for a number of reasons: they talk about their diet too much; make them as non-dieters feel bad about themselves for not dieting; find dieters grumpy and miserable; that dieters refuse to socialise and ban treats such as birthday cake.
