Posh, who is well known for her skinny body and her huge shopping bills, found stability in the move she made to Hollywood with hubby David and their sons Brooklyn, nine, Romeo, six, and three-year-old Cruz.
"I'm so content I've even been smiling a bit these days," the Sun quoted her as saying.
She also admitted, over lunch at the exclusive Polo Lounge at the Beverly Hills Hotel, to having had a weakness for shopping, which she has now stopped.
"You know, I could just go shopping every day and sit on my bum," she said.
"I could do what half these people do in here - sit and have lunch and go shopping - but I'd be so bored. I don't even go shopping any more," she added.
It has been just over a year since Victoria moved to LA, but still her life has changed dramatically.
She was known to have never entered a gym before, but now she is running four miles per day, and from eating nothing, she has developed a healthy appetite that contains even carbohydrate-loaded food.
"I run four miles, seven days a week," she explained.
"I feel energized and healthy - there are really nice gyms here and I just enjoy it. I need that self-discipline to get up in the morning, drop the kids off at school then go to the gym. I can think properly then go home and do some work. But I do feel so much better.
"David puts music on my iPod and Gordon Ramsay bought me trainers where you have a little chip so you can clock how far you're running." nd does she have a bigger appetite?
"Yes, I am eating more. I think you do eat more when you're working out. And you want to eat healthily, so it's good all round," she added.
