Victoria Beckham, 51, has opened up about the struggles of having an eating order in a new three-part documentary series released on Netflix.

The former Spice Girl, who rocketed to fame in the 1990s with the girl band, said being in the public eye placed her under huge scrutiny.

While she couldn’t control constant attention on her looks, she could try and control her weight, which led to an “unhealthy” way of eating.

“I had no control over what was being written about me or the pictures that were being taken and I suppose I wanted to control that,” she tells viewers.

“I could control it with the clothing, I could control my weight. I was controlling my weight in an incredibly unhealthy way.”

“When you have an eating disorder you become very good at lying. And I was never honest about it with my parents.”

Beckham said the criticism of her figure — being too fat or too thin — left her wondering what she was when she looked in the mirror.

“I really started to doubt myself and not like myself and because I let it affect me,” she says.

“Was I fat? Was I thin? I don’t know, you lose all sense of reality. I was just very critical of myself.

“I didn’t like what I saw. I have been everything from porky posh to skinny posh, I mean, it’s been a lot and that’s hard.”

Beckham said she never spoke publicly about her internal struggles.

One example of a difficult moment was when she was weighed on television for the UK program TFI Friday after giving birth to her eldest son Brooklyn in 1999.

“‘Get on those scales’… ‘Have you lost the weight?’ We laugh about it and we joke about it when we’re on television, but I was really, really young and that hurts,” Victoria recalls.

The series, Victoria Beckham, was launched at a celebrity event in London on Wednesday night (AEST), with guests including her fellow Spice Girls, minus Mel B who is working in the US.

It follows her husband David Beckham’s fly-on-the-wall series in 2023, BECKHAM, which explored his rise from humble footballer to global icon.

Beckham adds his own observations of his wife’s struggles during the height of their fame.

“People felt it was okay to criticise a woman for her weight, for what she’s doing for what she’s wearing,” he says on Victoria Beckham.

“There were a lot of things happening in TV then that wouldn’t happen now, that can’t happen now.”

“My Victoria that I knew, sits at home in track suit, smiling laughing, having a glass of wine.

“That started to go purely because of the criticism that she was getting.”

Beckham also talks about her life after Spice Girls when she flopped as a solo artist, her WAG era when she had a boob job and her move into fashion designing.

Victoria Beckham will begin streaming on Netflix in Australia on Thursday October 9 at 5pm.
