She was announced as the new poster girl for Atkins diet only one day ago.
And Kelly Brook was displaying her commitment to shedding the pounds on Wednesday when she slipped on her tightest fitness outfit and embarked on a morning hike.
The brunette beauty meant business when she grabbed petite gal pal Natalie Loren for support and headed out into Hollywood’s Runyon Canyon in her cap and trainers.

Commitment: Kelly Brook heads out for a morning hike at Runyon Canyon in LA with pal Natalie Loren on Wednesday
Kelly, dedicated to her new food plan and healthy programme, was strides ahead of her friends as she flaunted her curves in skintight leggings.
She revealed her toned upper arms in a zip-up gilet, which she wore right to the top to conceal her ample cleavage.
It was an altogether less glamorous ensemble than Kelly traditionally opts for because she was sticking to a muted palette of charcoal colours.

Unlike the feminine, low-cut bodycon dresses she’s familiar with; Kelly was sporting a more masculine look as she shielded her eyes from the sun in a black cap.
Kelly said 2014 had been a year where she neglected herself and didn’t focus enough on having a healthy diet, especially at Christmas.
She announced the decision on Wednesday when she tweeted: ‘Excited to Start the New @MyAtkins Plan. I over indulged this #Christmas Wanting to feel #Fit #lowcarb #lowSugar #ad’
Speaking about her decision to join the New Atkins Nutritional Approach, she said: ‘On the set of my new TV show, it was really easy to reach for the naughty treats, so I’ve noticed the changes in my body.

‘I’m guilty of having at least five cups of tea a day with two sugars in, that’s 10 spoons of sugar every day, just in my tea.
I’ve also had a brilliant Christmas but I have over-indulged a little, which I’m sure many people can relate to.’
Kelly has been a loyal gym bunny since meeting former Gladiator and personal trainer David McIntosh, who she’s yo-yo’d through engagements, cheating and break ups in the last year.
Discussing her goals, Kelly added: ‘I’m looking to lose a few pounds, but a more important goal for me is staying fit and healthy without having to deprive myself.’

Kelly was parading her curvaceous frame in a little white sun dress when she treated herself to a pampering treat on Wednesday afternoon.
She received a neck massage while having her nails manicured inside an LA salon after sharing her minimal meal plan on Instagram at every opportunity.
The healthy meals were a departure from the mince pies and juicy fish dishes that the brunette beauty has been posting of late.
