She has shed a whopping 18kg in the space of less than a year. 

And Jackie ‘O’ Henderson, 49, has admitted the exact amount she weighed before deciding to embark on her weight loss journey. 

She made the confession during Monday’s Kyle And Jackie O Show after the radio program welcomed a caller on-air who weighed 85kg. 

Curious newsreader Brooklyn Ross turned to Jackie and asked her, ‘Do you know what the biggest [you weighed] was?’ 

‘The biggest was 80’, she replied. 

Jackie’s admission comes after she was once forced to deny that Ozempic is behind her spectacular slim down.

Ozempic, an appetite suppressant previously used to treat Diabetes type II, has seen an increase in prescriptions for obesity in recent years and is now used by many celebrities to keep a trim figure.

Jackie has always insisted she achieved her weight loss by going on WW (Weight Watchers), which she was an official ambassador for.

But speculation  kicked off again after WW, under the leadership of CEO Sima Sistani, has started to embrace semaglutide drugs like Ozempic.

Reacting to the news on the The Kyle and Jackie O Show, Jackie exclaimed, ‘That makes it look like I was definitely on Ozempic!’

She jokingly added, ‘I was like a guinea pig in that experiment.’

Newsreader Brooklyn Ross then asked Jackie if she was ‘annoyed’ she had to lose weight ‘the hard way’ instead of just using a semaglutide for a quick fix.

‘I mean, they make a good point and I’m really impressed that they’re with the times,’ she said.

‘You see so many people doing it and being successful and it not really being that hard for them.’
