Elise Frank, 26, from Utah, US, works as a model but likes to be as real as possible online – and in this video demonstrates how what we see on social media isn’t always reality.

In the viral post, she shows how influencers can change appear to dramatically change their physique between 'before' and 'after' photos, even if nothing has in fact changed about their bodies.

For the 'before' shot, she makes herself look fatter by hunching her shoulders, drawing her buttocks in, pulling her waistband down, and putting her legs together.

Showing how they can look dramatically slimmer within seconds, she then pulls her waistband back up and adopts a straighter stance, turning her legs apart and feet facing slightly inward.

Elise also says they may take their hair down to cover their back, enhancing the “after” effect.

The post got over 3.9 million views and received over 340,000 likes.

One user commented: “Not even a lie. I was doing one of those eight-week challenges for an online influencer years ago and he LITERALLY told us how to make bad “before” photos,” another viewer quipped." [sic]

Someone else said: “I needed this reality check.”

“OMG I always noticed the low rise vs high waist! I’m so happy someone called it out,” another user commented.

Someone else wrote: “This kind of stuff needs to be shared more often. Not everything is as it seems, and too many young people see it and misunderstand it.”

“The hero we need and deserve, thank you for showing us this stuff. It definitely helps knowing what's real,” added someone else.

Another person said: “On behalf of every teenage girl seeing this, thank you."

The post came as part of a series in which Elise demonstrates how influencers "fake" other before and after shots, including how to lengthen hair, and another weight loss shot of them sticking out their stomachs before sucking them back in.

"I wanted to show people that life isn't always as it seems online, that posing and angles can totally change a person's body, and that people aren't alone in their own insecurities,” Elise, who is mum to three-year-old son Donovan, told Jam Press.

Elise was aware of the posing tricks because of her experience in modelling already and noticed the poses quite often.

She added: "It's easy to spot poses once you know the tricks and I started realising just how often people were using these tricks.

"I'm not against someone posing but I do wish people would be more apparent and more real online!"

Elise said of the reaction: "I've been in tears, the good kind, reading some of the comments on this and some of my other videos, because I have girls telling me that they struggle with eating disorders or body dysmorphia and that my videos have made a huge difference in their life.

"Or saying that they feel like my page is a safe space and how much I'm helping, I can't tell you how much that means to me because I just want to make a difference."

In the viral post, she demonstrates how influencers can change their physique for a dramatic “before” picture to demonstrate weight loss, hunching the shoulders, drawing the buttocks in, pulling the waistband of their trousers to sit on the hips, and putting their legs together.
