Victoria Beckham packed herself off to a German detox spa and ate a restricted diet of salmon, spinach, vitamin pills – and moon water.

Specialists promise to ‘restart your life’ at the retreat in Munich and guests pay top whack – over £3000 (AUD $5,500) a week – for the honour.

What’s more, top up packages that focus on the mind and body through exercise and detoxing are priced at £300 to £2500 (AUD $550 to $4600).

Busy mum of four Victoria, 45, filmed her stay and showed off her minuscule meals to fans on Instagram.

Breakfast consisted of a small omelette, ONE cherry tomato, a small avocado and a TINY side salad.

Later, the retired Spice Girl tucked into a salmon and wilted spinach dinner and sipped full moon water.

The bizarre drink is “charged with the energies of the moon” by being placed outdoors in a container beneath a full moon and costs £8 (AUD $15) a bottle, of course.

The fashion designer also worked up a sweat and followed a schedule of bike rides, treatments and relaxation.

But Victoria is used to working out and goes on a 7km run on the treadmill first thing every morning at home.

“A mix of uphill fast walking, jogging, running,” she told the Guardian last year.

Victoria works out for two hours a day and insists it isn’t a slog, saying she really enjoys catching up with her TV in her home gym.

“That’s the only time I watch TV – boxsets, documentaries – so I look forward to that,” she said.

The slender star gets up between 5.30am and 6am every day to get started on her gruelling workout regime before taking a break halfway through for the school run.

“It takes 45 minutes. Then I work out with a trainer – 30 minutes legs, 30 minutes arms, toning and conditioning, then loads of planks and that kind of thing for my core,” she continued.

The busy mum does the whole two hours in one go at the weekend but stops during the week to drive the kids to school and then carry on when she gets home.

“I work out every day when I’m at home, and then when I travel I really focus on work so I can get as much done as possible in a short trip and get home,” she said.

Victoria said exercise is “really positive” and a “part of who I am now”.

But the slim star doesn’t pretend her slender figure is all down to exercise – she also follows a precise diet.

“I am very, very disciplined in the way that I work out, in what I eat,” she added last year.

“That’s how I’m happiest. I expect a lot from my body – I’m 44, I’ve got four kids, I work a lot, I travel. For me to do all that, I have to eat healthily and work out.”
