At her heaviest, Chloe Cox weighed 120kg.
She couldn't do much, nor did she want to. Instead, her daily routine would consist of splurging on takeaway, junk food and heading to her local McDonald's to satisfy her chocolate frappe cravings, at least four times a week.
On top of that, Ms Cox couldn't find the energy to do any exercise.
"Everything I did was a struggle, even walking to the letterbox," Ms Cox said. "I would avoid going out to social events. I just felt so low within myself and I hated going out.
"Growing up, I was the kid at school who always had a note to get out of P.E. class."
It was when her mother sent her a photo holding her two kids who were 18 months and one week old at the time, that she realised how much she "hated" what she saw.
Ms Cox had experienced two high-risk pregnancies with blood pressure issues and other health concerns that also prompted her to make a change — especially if she were to have another baby.
"With my first child I was on bed rest. I was bleeding the whole time because I was so overweight my body couldn't handle it," she told news.com.au
"I had my second child at 36 weeks due to my blood pressure being too high and overall health issues."
"I had post-natal depression after my first child. I sunk pretty low and I never want to experience that feeling again. I wanted to do everything to be happy and active."
Earlier this year, Ms Cox gave birth to her third child in what she described to be a "text book" pregnancy.
"I had absolutely no issues at all. It all came down to the changes I made."
The pregnancy came after the 25-year-old from Bonnells Bay in NSW embarked on a life-changing fitness journey which saw her lose 40kg over 15 months.
Admittedly, the full-time mum said there were times she wanted to give in, but kept her focus on achieving short-term goals, with her happiness, good health and kids as her priority.
"Focus on one thing at a time and not at six months down the track. Just ask yourself, 'What can I do today that's better than yesterday,' because each step is a step in the right direction."
"Before I would watch my kids play from the sideline. Now I make an effort to run around with them or go for long walks, because every bit counts."
Ms Cox now exercises three to four times a day at the gym (mainly group classes) with her diet all about portion control, moderation and very limited junk food.
"I eliminated most packaged foods and we cook together as a family. You don't have to eliminate the tasty food. You can still eat it but in moderation and at better times."
Ms Cox said she owes her transformation to The Healthy Mummy, a parenting health site exclusively for mums who support one another through their health journey.
They've helped mums lose three million kilograms collectively through programs combining healthy recipes, fitness and advice.
"The online support groups are particularly helpful because you have thousands of other women in the same boat and there is always someone their to boost your confidence and get you going again."
Since shedding the kilos and transforming her life, Ms Cox joined the site as its admin and social media manager, and said while it can be tough juggling exercise, full-time mum duties and work, she reminds her fellow mums it can be done.
"Any form of exercise goes a long way."
