Sarah Harris says pregnancy has stopped her from going back to her chain-smoking habit.

There’s no denying pregnancy and cravings usually go hand in hand. For Sarah Harris, having a baby proved to be the best thing to stop one craving in particular – cigarettes.

In an interview with Body + Soul, the Studio 10 host said after finally giving up chain-smoking in February, being pregnant has proven to be the secret to quitting for good.

“It was ingrained in my psyche that to be on-this-road reporter, I needed to be durrying on. But having this baby growing inside me is the best incentive to stay off them,” she said.

“I don’t even feel like one now and I feel so much better for it.”

And as for the other cravings? Stodgy food, hamburgers and steak proved to be the only thing that could settle her stomach during the first trimester.

“I wish I could say I was drinking green tea and alkaline water and eating activated almonds but I wasn’t. It was the only way I could settle my stomach,” she said.

Almost seven months into her pregnancy, Harris has already become the target of body shamers. (Post continues after gallery.)

Just last week, the 33 year old was forced to defend her bump on Studio 10 after commenters left horribly negative comments on a photo of her published by Daily Mail.

“Some of them were just revolting. Having a go at how huge I am, how fat I am, how ugly I am…When you’re pregnant you do feel very vulnerable and self-conscious about your body. And it did feel pretty awful about the comments and the pictures but then I thought, do you know what? Bugger it. I’m growing a baby, this is me,” she said on Studio 10.

“When you work in TV, you’re very conscious of your body and what size you are, so there’s something quite freeing about being pregnant. It’s completely changed the way I feel about my body,” she told Body + Soul.

“I trust that it’s doing what it needs to be doing right now to grow a healthy human. It’s put into perspective how important it is for me to be strong and that’s my mindset now.”

It’s positivity that her husband, Tom Ward, who she married in July last year, has had a helping hand with by discouraging any negative language about her body.

"At home if I start using derogatory language about myself, whether I’m having a fat day or feel disgusting, Tom will pick me up on it and say, ‘Don’t use that sort of language’, because we don’t want to use that language around our kids when we have them,” Harris told News.com.au's ‘On the Couch’ series.

While she's ensuring she keeps healthy with regular walks "with nerdy podcasts", barre classes and pregnancy Pilates, getting 'her pre-baby body back' is not at the top of her priority list.

"The industry I'm in is very, very narcissistic but I think there's more to life than being able to fit into skinny jeans or a mini skirt," she says.

"I also think we should set an example for our kids that what's important isn't the size of your bum or whether you have love handles but being kind, being genuine and having a strong sense of self."

We can't think of a better example of all of those than you, Sarah - bravo.

How did you deal with body image and confidence while pregnant?
