Kelly Brook is clearly eager to show off the results of her new weight-loss mission, as she shared snaps with fans on Instagram on Thursday during a night out with her pals in Los Angeles.

The 35-year-old posted another video in which she posed against a palm tree wearing her entire outfit.

Kelly wore a low-cut grey top with black skinny jeans and a leather jacket, and she accessorized with netted peep-toe heels.

Kelly Brook demonstrated her commitment to losing weight on Wednesday by donning her tightest fitness outfit and going on a morning hike.

The brunette beauty took her petite gal pal Natalie Loren with her and headed out into Hollywood’s Runyon Canyon in her cap and trainers. 

Kelly, who was committed to her new diet and healthy lifestyle, was miles ahead of her friends as she flaunted her curves in skintight leggings.

She showed off her toned upper arms in a zip-up gilet that she wore all the way to the top to hide her ample cleavage.

Kelly was wearing a less glamorous outfit than she usually does because she was wearing a muted palette of charcoal colors. 

Kelly was wearing a black cap to shield her eyes from the sun, as opposed to the feminine, low-cut bodycon dresses she is used to.

Kelly stated that 2014 was a year in which she neglected herself and did not place enough emphasis on eating a healthy diet, particularly during the holidays.

She announced her decision on Twitter on Wednesday, writing, ‘Excited to Begin the New @MyAtkins Plan. I overindulged this #Christmas in the hopes of feeling #Fit #lowcarb #lowSugar #ad’ 

‘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,’ she said of her decision to join the New Atkins Nutritional Approach.

‘I’m guilty of drinking at least five cups of tea per day with two sugars in them, which amounts to 10 spoons of sugar per day just in my tea. I had a wonderful Christmas as well, but I think many people can relate to my overindulgence.’

Kelly has been a gym rat since meeting former Gladiator and personal trainer David McIntosh, with whom she has gone through engagements, cheating, and breakups in the last year.

‘I’m looking to lose a few pounds, but a more important goal for me is staying fit and healthy without having to Ԁeprive myself,’ Kelly explained.

Kelly has admitted to neglecting herself in 2014, including her commitment to a healthy regime. 

Kelly was wearing a little white sundress and flaunting her curvaceous figure when she treated herself to a pampering session on Wednesday afternoon.

She got a neck massage while getting her nails done in a LA salon after constantly posting about her minimalist diet on Instagram.

The healthy meals were a departure from the brunette beauty’s recent posts of mince pies and juicy fish dishes.
