Loose Women star Saira Khan said she felt "brilliant" after going on a Mediterranean juice retreat to get rid of her "bloat".
The former Apprentice contestant shared before and after pictures of her body after living off just four fruit and vegetable juices a day for a week.
She told followers on Instagram it wasn't a diet but but an "enlightened way to understand the power of fruit and veg".
Compliments flooded in for Saira's toned new look, with one telling her she looked "healthy and glowing".
Saira wrote: "I came here to get rid of my bloat, relax, recharge and revitalise myself. I’ve feasted on 4 fruit and veg juices a day, full of minerals, vitamins and antioxidants.
"I have not had any adverse symptoms at all. Have not felt hungry once. I’ve had 2 colonics one coffee and one wheatgrass - which I feel were brilliant for me.
"I have no idea how much weight I’ve lost- I have not weighed myself- but it’s not about the weight- it’s about how I feel."
Saira added that she was on a "juicy high" and said she would recommend it to anyone who wanted to change their diet mindset.
In another photo from the retreat Saira posed in a bright yellow bikini, writing: "Learning so much about my body, food, nutrition, exercise, health!
"Everyone is a different shape, size and age, but we are all embracing the “break” from our hectic life.
"Whatever you are doing today, make it count, and do it for yourself."
Saira was a runner-up on the first series of The Apprentice and is now one of the most outspoken members of the Loose Women panel.
