Actress Myolie Wu Hang-yee, who gained 18 kilograms for a new TVB sitcom, will have to shed at least 13kg in just one month to finish the show.
Wu (right) said she hadn't started losing the weight yet, but had picked a slimming company to help her.
She denied reports that slimming companies were bidding to provide her with the service, saying she only wanted to lose weight in a healthy way.
'I don't want to take any slimming pills,' Wu said. 'The rumours that I chose the highest bidder aren't true.'
She said actress Lisa Wang Ming-chuen, a spokeswoman for a slimming company, had called her and assured her that she would lose the weight.
'I'm really looking forward to being slim again,' said Wu, who weighed 50kg before the show. 'I hope to not only lose weight, but also get a better figure.'
