Viewers have lost their appetite for TV's clean eating queens as Hemsley sisters' ratings crash after three episodes

They must have hoped their eye-catching outfits and 'clean eating' recipes would keep viewers coming back for more.

But audiences are already abandoning the Hemsley sisters in droves – just three episodes into their Channel 4 series.

Jasmine, 36, and Melissa, 30 – who have no formal nutrition qualifications – have seen viewing figures plummet since the show was unveiled, falling from 926,000 to 342,000.

Now the broadcaster has decided to move Eating Well With Hemsley + Hemsley from its primetime Monday evening slot to the less prestigious Friday – when audiences are expected to be out and not watching TV.

The embarrassing move takes effect from next week for the series' final two episodes. Even a source close to the show had to admit: 'It seems Britons are finally fed up with being patronised by clueless skinny 'cooks' telling us to spiralise courgettes.'

The programme sees the raven-haired siblings Jasmine, 36, and Melissa, 30, wax lyrical about 'clean eating' – a current fad pushed by the likes of 'Deliciously' Ella Woodward, which tells adherents to abandon gluten, sugar and any processed food. 

It is perhaps hardly surprising given that six years ago there were working in entirely different careers - Jasmine and a model and Melissa in marketing – and hold no formal qualifications in diet, nutrition or cookery.

They have even failed to find a proper foothold on social media, with their account on photo sharing site Instagram boasting only 240,000 followers, compared to 856,000 for Miss Woodward and more than 4million for a chef such as Jamie Oliver.

The sisters emerged as food experts after a holiday to Australia in 2009, and have two recipe books and a cafe to their name. 

The following year, through their showbiz contacts found an well-known – but still unnamed – actor who was willing to pay them to help with his diet.

Their business boomed and they have catered for the likes of Vivienne Westwood and Louis Vuitton and count Downton Abbey star Michelle Dockery and heiress Millie Mackintosh among their fans.

The pair, who were born in Surbiton to a Filipina mother and lieutenant-colonel father, appear to have no qualms about using their looks to keep TV viewers entertained, gazing doe-eyed at the camera and wearing outfits that flatter their skinny figures. 

Even more damning than the ratings are criticisms from real nutritionists who claim the clean eating fad can lead to eating disorders.

Dietician Renee McGregor previously told the Mail: 'They're basically saying: if you eat like us, you'll look like us — which isn't true. They're playing on their looks to influence people and make them buy into their philosophy.'
