A TV ad for Vicky Pattison’s best-selling fitness DVD has reportedly been banned for being ‘misleading’.

The Geordie Shore star said she has shed three stone in the past six months, dropping from a size 16 to a size 6.

Vicky’s fitness DVD cover shows a ‘before and after’ bikini picture of the 26-year-old celebrity.

The DVD, called Vicky’s 7 Day Slim – knocked Davina McCall’s Davina: Fit in 15 off the number one spot earlier this year.

A voice-over on the TV ad for the DVD said, “Here’s Vicky from Geordie Shore before she found 7 Day Slim…..now look at her!”, with Vicky then saying, “I’ve lost three stone with this DVD.”

On-screen text said, “Weight lost over six months. Works as part of a calorie controlled diet.”

Bosses at the Advertising Standards Authority (ASA) are said to have banned the ad for misleading viewers into thinking they could lose three stone in just seven days.

It criticised the ad for its failure to clarify in sufficiently readable text that the 7-day slim workout refers to weight-loss over 12 months with a calorie controlled diet.

However, bosses at Universal Pictures (UK) Ltd – which made the DVD – said the product name 7 Day Slim referred to a weekly cycle of seven workouts to be repeated over time in order to achieve significant weight loss and that Vicky weight loss took place over six months.
