Just last week she hit out at online trolls, who criticised her for losing weight.

Dokic lost 20kg in 10 months and has stressed that it’s about “health and not size”.

In a lengthy Instagram post, she said the “most important thing is that I am happy and proud in both pics regardless of my weight and that I am kind always.”

She went on to share her secrets, but added that weight loss was not a priority, it was just a byproduct of looking after her health.

“I stopped eating late at night especially things like burgers, pizza, fries and desserts because they made me feel so sluggish when I would wake up especially for early morning work and flights. So I don’t eat heavy meals at night anymore and I don’t eat after 7pm,” she wrote.

“I eat more salads and soups for my meals now like a chicken caeser salad or tomato soup with multigrain bread. This type of meal does not make me feel sluggish and I am full.

“I drink more water now and I have cut back on soda, even diet soda.

“I have also added a meal replacement shake and I will do a seperate post on that tomorrow but I have been using HealthyTrim meal replacement shakes for almost a year now. I use them once a day and I also use them for smoothies, smoothie bowls and overnight oats which has replaced some of my desserts.

“It’s small changes over time and while I still have my cheeseburger and fries days, it’s just a lot less and I definitely don’t eat junk food when I am working and traveling.”

Dokic added that she is not an expert and just shared what worked for her.

“I didn’t lose weight quickly, I lost 20 kilos in just under 10 months. Nothing fast,” she said.

“It was small changes over time that I wanted to be able to sustain. There was no diet and I didn’t worry about the number on the scale.

“I have a family history of diabetes and high blood pressure and I started to have high blood pressure. Also, I was really sluggish and didn’t have enough energy for my very busy and hectic lifestyle.

“I couldn’t keep up and I didn’t have enough energy especially mentally and I needed to change that.”

Dokic has been in Paris commentating at the French Open and will be off to London in two weeks for Wimbledon.
