Victoria Bekham London - Arabstoday You\'d think after having four children any hopes of having a flat tummy would be over - but one woman is determined to prove otherwise. After giving birth to Harper Seven last month and gaining 1st 7lb, Victoria Beckham has gone into hiding in a bid to get back to a svelte size zero. While Mr Beckham has been spotted almost daily with the rest of the brood, it is claimed 37-year-old Victoria has been cooped up in a rented seven-bedroom Malibu mansion getting her body back to pre-pregnancy glory. According to Grazia, the former Spice Girl has been following the new \'Five Hands\' diet to taper her figure in time for a grand unveiling at New York Fashion Week from September 8-15. With a matter of weeks to go before she makes her return to the spotlight, Victoria has reportedly been sticking to the strict regime which consists of just five handfuls of food a day. A source told the magazine that she has cut out sugar and has been snacking on miniscule portions of smoked salmon, prawns with chilli, yellow-fin tuna sushi and scrambled eggs. They said: \'Victoria wants to be in the best shape she can in time for New York Fashion Week. \'Five days after giving birth, she started eating five high-protein meals a day accompanied by green vegetables, drinking gallons of water, and only snacking on goji berries and nuts.\' To complement her new eating plan Victoria has also been doing gentle exercise at the £93,000-a-month beach rental owned by Stephen Spielberg, as doctors have warned against any vigorous exercise for at least eight weeks following her caesarean. \'Victoria\'s been doing gentle post-natal exercises and 10 minutes of Pilates. \'In a few weeks\' time she\'ll pick up her normal gym routine again and start training with Tracy Anderson,\' the source added. This isn\'t the first time that the fashion designer - who will be shortly be exhibiting the spring 2012 collection of her eponymous label in New York - has fought to shed her pregnancy pounds. Following the birth of her three sons Brooklyn, 12, Romeo, eight, and Cruz, six, Victoria used a combination of Pilates and algae wraps - which reportedly shed 2-3lb a session - to regain her slender appearance. Images of her after the birth of her first son Brooklyn, in 1999 sparked concern over her rapid weight loss. At the time, she said: \'I had become Skeletal Spice. What upset me was I ate like any normal person... I wasn\'t happy with how I looked.\' (Dailymail)
