Aussie mum Kourtney Campbell has shared how she was able to lose an incredible 40kg, thanks to completely overhauling her diet, and getting some exercise help from fitness influencer Tammy Hembrow.

Kourtney, from Brisbane, weighed 105kg at her heaviest, but decided to make a change to her lifestyle after she separated from her daughter's father and became a single mum.

"I used being pregnant as an excuse to eat whatever I wanted to, and I had a really crap pregnancy," Kourtney, who welcomed her daughter in 2019, tells Yahoo Lifestyle.

“Eating whatever I wanted, I had almost 1 litre of Coke a day. I had lots of sugar, junk food and three servings of dinner at night,” she admits, adding she got to a point where she was too anxious to leave the house.

She missed out on many family activities - including Christmas – because she "didn’t want to be seen in public".

The social anxiety didn’t stop there, she didn’t take her daughter to the beach or pool for the first time, adding, "to any of her 'firsts' really because I was too self-conscious to be outside."

"I wouldn't go out for days, I didn't want to go out and do things with my family, just because I was so anxious about what people were going to say, if they had seen how much weight I'd put on."

But last year, the mum realised things had to change when she became a single parent, and started altering her lifestyle, dropping 36kg since then.

She not only eats healthier meals now - she has learned to have a wholesome relationship with food in general.


"I think the biggest change was food," she tells us. "I lost a lot of my weight just through changing my diet."

Kourtney was able to lose 25kg thanks to the changes she made to her diet, but then she also found her love and motivation for exercise when she jumped on the Tammy-Fit fitness app.

It would alert her with different messages every day, reminding her to drink more water or to hit the gym.

“I’m really proud of my body now. I’m shopping at stores I didn’t think I’d be shopping at," she says.

She's even getting a lot of messages from other mums on social media asking about her transformation.

"I've had a lot of moms messaged me," she says.

"But I tell them just remember that you've had a baby, your body has change in those nine months. And it's going to take, you know, it's going to take time."

"And don't wait for motivation to come you have to go and create the motivation. It's an hour a day. That's a TV show, pick a TV show and go and just work out or go for a walk. Put on a playlist, and even on the days that you feel crap, Even just shy out for 20 minutes counts for something.
