The diet paid off then! TOWIE's Frankie Essex shows off her slender bikini body after losing a stone in just TWO WEEKS

By Ian Garland

Frankie Essex has won her fight with the flab, shedding a whole stone in just two weeks.

The Only Way is Essex star showed off her slender new figure in the Marbella sunshine yesterday - just a fortnight after she started a gruelling diet and exercise regime in a desperate bid to swap her muffin top for a toned tummy.

And while Frankie may not have managed a six pack, all that sweat and starvation clearly paid off as there was barely a stretch mark or inch of fat on show.

Frankie piled on the pounds during a recent trip to Miami with TOWIE co-star Lauren Goodger.

The pair overindulged during their American vacation and made a pact to lose weight when they returned.

They started following the Cambridge Diet Plan, dropping their calorie intake to just 400 a day.

And Frankie signed up the services of personal trainer and Big Fat Gypsy Wedding star Tony Giles to whip her into shape.

Frankie and Tony were photographed on April 17 working out in an Essex Park.

She seemed well aware of her excess weight, grabbing her belly while exercising and pinching the fat on her thighs.

Tony - who is engaged to glamour model Danielle Mason - put Frankie through her paces making her do star jumps and squats, before strapping on boxing pads and sparring with her.

She clearly stuck to the work out sessions and the diet shakes.

Frankie showed off the effects of her weightloss during a night out in Marbella on Sunday night, posing with friends and TOWIE co-stars Billi Mucklow, Cara Kilbey in a trio of red, white and blue matching bandage dresses from Celeb Boutique.

Lauren Goodger proudly displayed her own diet efforts during a night out on April 23.

She looked back to her slender best, but revealed she still wants to lose two stones before she'll venture back into a bikini.

She said: 'I want something quick because I’m going away again soon.

'I want to go to Marbella and Ibiza and when I’m walking around I want everyone to go, ''My God, have you seen Lauren?''

'The quick fix will act as a motivator for me.'
