It's no secret how Victoria Beckham stays so very thin -- the girl doesn't eat much. It's not through physical activity seeing as how she hates wearing any sort of flat shoe. Not exactly a healthy role model for weight loss, but unfortunately Britney Spears seems to have picked up on some of the ways Posh stays slim and is trying to follow that diet.

According to the Daily Mail, a source in L.A. says, "She's been eating steamed fish and edemame beans. She was told that's how Victoria stays so slim." Doesn't sound so bad, right? Just wait -- it gets worse.

"She is also drinking goji berry juice and seaweed shakes to stave off hunger and starts each day with a cup of hot water and lemon." I hope Britney and her trainers realize that Posh may be slim, but she's not healthy -- I'm happy to see Britney hitting the gym, and if she keeps that up and eats healthfully, she should be in great shape before you know it. No need to resort to seaweed shakes (unless she likes them, but I think it sounds gross!).
