Scarlett Johansson speaks out to deny 'irresponsible' crash diet rumours

has vehemently denied going on a crash diet, saying she has simply been hitting the gym to tone up for a film role.
In an article she has written for an American website the actress expressed her distress at articles saying she had lost a stone.
Scarlett, 24, says she is worried the reports might encourage others to start eating unhealthily.

'I'm someone who has always publicly advocated for a healthy body image and the idea that the media would maintain that I have lost an impossible amount of weight by some sort of "crash diet" or miracle workout is ludicrous,' she wrote in her article for The Huffington Post.
'I  would be absolutely mortified to discover that some 15-year-old girl in Kansas City read one of these "articles" and decided she wasn't going to eat for a couple of weeks so she too could "crash diet" and look like Scarlett Johansson.'

Scarlett says that in her experience the only effective way to lose weight is to exercise and eat healthily, something she has been doing in preparation for her role as as the Black Widow in Iron Man 2.
'There is no magic wand to wave over oneself to look good in a latex catsuit.
'Eating healthy and getting fit is about commitment, determination, consistency and the dedication to self-preservation.
'While I've never been considered a gym rat, I have, in fact, worked up a sweat in the name of cardio before, and although I enjoy a grilled cheese as much as the next person, I combine the not-so-good foods I crave with an all-around balanced diet.'
Scarlett was widely reported to have lost a stone with the help of Gwyneth Paltrow's trainer Tracy Anderson, something she denies.
'If I were to lose 14 pounds, I'd have to part with both arms. And a foot,' she wrote.
