Rebel Wilson isn't going to let a little bump in the road stop her from conquering her goals.

The comedian recently revealed on Twitter that she was embarking on a challenge to completely eliminate refined sugar from her diet, but she ran into a bit of a snag on day 20.

"I lost the NO (refined) SUGAR CHALLENGE after 20 days…had a scary taxi ride and succumbed to ice-cream & Mars Bar…but back on wagon," she wrote yesterday.

Wilson, who is currently tweeting from her vacation in Dubai with boyfriend Mickey Gooch Jr., noted to fans that she hopped right back on the health train almost as quickly as she fell off.

"I'm going great, feeling great, resisting all processed sugar," she told one follower after they asked about her progress.

Of course, there's been plenty of discussion surrounding Wilson's figure in the recent months.

Earlier this year, the Pitch Perfect 2 star opened up about why she felt that her physical appearance was her biggest asset.

"I took something that was seen as a disadvantage--no one thinks, if you're fat, that you're going to be an actress and everyone's going to love you--and turned it into a positive," she told Australia's Daily Life.

"I do have these dreams, like, 'What if I just went to a health farm and lost 50 kilos? What would happen? Would it affect my career?'" the actress confessed. "But then I think, that's never going to happen."
