Casey Batchelor lost one stone in one month thanks to her new diet and yoga regime.

The 33-year-old reality star welcomed her daughter Florence - whom she has with her boyfriend Dane Goodson - into the world three months ago, and has been documenting her fitness journey on Instagram as she works to get back her pre-pregnancy body.

And the new mum took to social media on Tuesday (11.09.18) to share a side-by-side photo of herself in August compared to a month later in September, showing off her dramatic weight loss.

She wrote alongside the image: ''So guys I wanted to share this with you as I'm so thrilled to say that I've lost a stone in a month doing my yoga and being good with my diet. Not back to my old bod yet but getting there #weightlossjourney #beforeandafter (sic)''

The former glamour model was flooded with comments from fans who praised her weight loss.

One said: ''You look incredible well done @caseybatchelor1 always keeping it real and no airbrushing or filters.''

Another said: ''Looking amazing thank you for being so honest and inspirational to other new mums! X'' (sic)

The 'Celebrity Big Brother' star is open about her changing body and new life as a mum, and has often posted frank and honest posts about her weight gain on social media.

In August she posted a before and after photo with two images of herself standing on a beach in a skimpy bikini comparing her 2016 slimmer physique to her 2018 one.

She wrote: ''Here is my TBT Throwing it way back to 2016.

''When I look at these pictures I feel good about how I looked then but refuse to feel bad about how I look now. In fact I'm using myself as my own inspo.
