Her extreme diet can see her eat up to 15 bananas, 40 pieces of fruit and a couple of kilograms of potatoes in one day.

But Freelee The Banana Girl, who has 492,794 YouTube subscribers and more than 329,000 Instagram followers, said her simplistic approach to food is the best way to lose weight and improve your health.

The Adelaide resident has written an e-book, the Raw Till 4 Diet Banana Girl Cleanse, and told Daily Mail Australia the diet, which encourages between 2,500 to 3,000-calories a day, would 'change your life.'

Extreme diet: Her raw till 4pm vegan lifestyle can see her eat up to 15 bananas for breakfast in a smoothie

Freelee’s own journey started nine years ago.

The 35-year-old was overweight, depressed, suffered from irritable bowel syndrome, chronic fatigue, poor digestion and acne.

She started to research nutrition and came across the raw food diet.

After trial and error, which included a stint of eating only bananas for a month, her high-carb fruit diet saw her shed 20 kilograms, and her health problems disappeared with the weight.

‘I was just so unwell and when I found this lifestyle and started implementing it I thought this is amazing, I need to tell the world,’ she said.

The Raw Till 4 Diet Banana Girl Cleanse includes a 30-day meal plan, exercise guide and 55 vegan recipes.

Freelee said in a typical day she would eat a smoothie for breakfast, fruit for lunch and a vegan meal for dinner.

Feeling fruity: The e-book encourages people to eat like Freelee and the raw till 4pm concept is said to aid digestion

‘A typical day would be about 10 to 15 bananas for breakfast in a smoothie,’ she said.

‘For lunch I have more fruit, whatever is in season really.

‘If it’s stone fruit I might ease a massive plate of stone fruit, like 30 or 40 peaches.’

Freelee disputed criticism that her diet was ‘boring’ or not ‘satisfying’.

Counting calories: Freelee's food pyramid lists fruit as the primary food source, with a minimum of five bananas a day

‘Your tastebuds appreciate simplicity and so does your digestion,’ she said.

‘If you eat that simple it tastes amazing and you receive all the goodness from the food without it complicating the digestive process.’

For dinner her favourite meal is ‘a couple of kilos of potatoes' that she chops and bakes.

Freelee said the raw till four concept helped with digestion and she preferred fruit as it is easily digested.

‘You feel better, you feel lighter, more energetic, happier,’ she said.

‘Rather than our bodies being weighed down my meat and dairy which is hard to digest.’

She encouraged people to adopt the diet for a 30-day cleanse.

Inner cleanse: She said the diet helped her lose weight, clear her skin, helped her depression and other health problems such as poor digestion and irritable bowel syndrome

As well as her fruit-based diet, Freelee is as an extreme advocate for veganism.

The YouTube star often takes aim at non-vegan celebrities in her videos in a bid to educate people about the meat industry.

The confronting and controversial content has seen her the victim of online trolls, but Freelee said it does not phase her.

Outspoken vegan: Her YouTube videos are confronting and often aimed at certain celebrities

‘More than 500 billion animals are slaughtered every year across the globe,’ she said,

‘People need to know what they’re supporting.

‘Imagine if people had to kill that lamb before they ate it, how many people would actually do that.

‘You’ll line up for your little bit of meat, but would they kill it? No they wouldn’t.’

Animal activist: ‘Imagine if people had to kill that lamb before they ate it, how many people would actually do that,' she said

Not concerned: ‘Naturally when you’re putting something people find controversial out there they definitely try and hate on you,’ she said

Freelee said her book was aimed at women between 15 and 30 years old and sold more than 3,000 copies in the first 24 hours over New Year’s Eve.

The book also contains a running guide.

‘Naturally when you’re putting something people find controversial out there they definitely try and hate on you,’ she said.
