Johanna Griggs has unleashed a blistering takedown of a "moronic" article about her.

This week, Australian tabloid magazine Woman’s Day shared the secrets to Johanna Griggs‘ recent weight-loss. “Joh’s rules for dropping 5kg FAST!” the headline read. “The beautiful TV star trimmed down with three simple lifestyle changes and you can too.”

But as the former Olympic swimmer herself pointed out via social media, there’s a, erm, slight problem with this article: there was no weight-loss.

Sharing an image of the spread to Instagram, the 44-year-old addressed the tabloid publication: “Let’s count how many random, completely inaccurate things you’ve come up with this week. 1. I’ve lost 5 kilos NOPE. 2. I’ve adopted a healthier food plan NOPE (I always eat healthily) 3. I’ve stopped eating after 8pm. NOPE (I’m often not even home before then) 4. I’ve embraced a ‘Farmhand Workout’ NOPE (What even is that?)”

The House Rules host goes on to debunk a further 10 claims made in the article, including that she sticks to dark-coloured fruits and vegetables and that she has adopted an “unusual weight lifting regimen” that involves carrying hay bales alongside her husband, Todd Huggins.

“If there was an award for Creative Writing – you’d win. Alas, there’s not so I’m suggesting a people’s choice award… something like, ‘The Moronic Award for Made Up Shite’.”

@womansdayaus If there was an award for Creative Writing – you’d win. Alas, there’s not so I’m suggesting a people’s choice award… something like, ‘The Moronic Award for Made Up Shite’ Let’s count how many random, completely inaccurate things you’ve come up with this week. 1. I’ve lost 5 kilos NOPE. 2 I’ve adopted a healthier food plan NOPE (I always eat healthily) 3. I’ve stopped eating after 8pm. NOPE (I’m often not even home before then) 4. I’ve embraced a ‘Farmhand Workout’ NOPE (What even is that? ????????) 5. I’ve stopped snacking on the run NOPE 6. I cover all food groups at every meal NOPE. 7. I try to stick to darker coloured fruits and veggies NOPE 8. I now only stick to Whole Foods NOPE 9. I eat porridge for breakfast (can’t remember the last time I did that) NOPE 10. I eat light rye sandwiches and salads for lunch NOPE 11. I pack fruit in my bag so I stop snacking on biscuits on set – Again – that would be a NO. 12. I’ve adopted an unusual weightlifting regime which according to your story means I carry hay bales alongside my hubby (good little wifey that I am) Again NOPE – 13. I don’t lift weights. And haven’t since I stopped swimming… and 14. I don’t go to the gym. Funnily enough the last two things you say I don’t do – I actually do – so by my calculations you have managed to write an entire article that is 100% inaccurate. #womansday #makinguprubbishforyears #creativewriting #absolutebulldust #100%rubbish #stopbuyinggossipmags @channel7 @bhgaus @houseruleson7

Griggs then concluded her blistering fact-check by pointing out that even the “don’ts” listed in the article are wrong.

“Funnily enough the last two things you say I don’t do – I actually do,” she wrote, “so by my calculations you have managed to write an entire article that is 100 per cent inaccurate.”

It’s not the first time the mother-of-two has accused the publication of printing false information. In July last year, she posted to Instagram about alleged falsehoods in a Woman’s Day piece about her husband’s “secret health crisis”.

Under the headline, “Joh’s miracle: I saved my husband’s LIFE”, the magazine claimed that “if it wasn’t for her ‘sixth sense’, Joh may have lost the love of her life” after she discovered a growth in his throat.

In an open letter to magazine, she wrote, “For the record: I didn’t have a 6th sense about anything… nor did I save my husband’s life. The doctors and medical staff who looked after him did.

“Todd wasn’t rushed off to hospital like you’ve made up in your fantasy world. In fact we booked in to see specialists and doctors and in to the hospital like thousands of other families do every year.”
