Fitness freak Gwyneth Paltrow was faced with quite a calorific challenge while training with chefs in a London restaurant kitchen – the actress was put in charge of the deep-fat fryer.

The ”Iron Man” star is known for her extremely strict diets, exercise and yoga regimes, for maintaining her lean figure.

Paltrow recently admitted that living in Britain and becoming a mother of two has ruined her once ultra-healthy lifestyle.

“A few weeks ago, I had the pleasure of spending the day working in London”s famous River Café, and it was incredible! The kitchen runs with a precision you would expect but a calm you perhaps would not,” the Daily Star quoted Paltrow as she wrote on her Goop newsletter.

“Once service started, I was stationed at the deep fat fryer (Delight! Fried zucchini! Fried anchovies!), and also helped Danny on pasta with his very busy day. It was an experience I won”t soon forget,” she added.
