Johansson packs on the pounds for TV diet spoof

Scarlett Johansson, Jessica Biel, Jessica Alba and many others star in a hilarious new TV spoof satirizing extreme weight loss infomercials and celebrity diet trends. The parody skit aired on Jimmy Kimmel Live and advertises the ‘Jimmy K’ diet plan.

The three actresses claimed to have been converted to the ‘Jimmy K’ diet, and their faces were superimposed onto pictures of overweight (and sometimes male) bodies.

Alba is featured standing next to a photo of a man in a yellow bikini holding a cake, claiming to have lost 49 pounds. There are similar photos of Biel and Johansson as well.

"Hi. I'm world famous. And thanks to Jimmy K, I'm not a big fat f****** whale," Biel says matter-of-factly to the audience.

Johansson adds that before she found ‘Hottie Body Jim-Miracle Diet’, “I hired a ninja to slap the food out of my hand before I could eat it.” Emily Blunt admits that she “swallowed a tape worm” in an effort to stay fit before she was made aware of this miraculous new diet.

Kimmel explains that the plan works by him eating four fifths of their meals, “to reduce calories by four fifths- that’s 80 percent!”

Neil Patrick Harris plays the scientist. We’re all familiar with the host who eagerly puts on the lab coat while discussing medical matters.

‘Fattening foods are subjected to powerful slimming forces which strip away 80 per cent of the carbohydrates, proteins and fats and divert them directly into Jimmy's stomach, where they are digested,’ he explains.

Zoe Saldana, January Jones, Emily Blunt, Amanda Seyfried, Kristen Bell, Anna Farris, Kerry Washington, Marisa Miller, and Heidi Klum also make guest appearances in the skit.
