The ‘Cinderella diet challenge’ is going viral on Twitter and FFS, REALLY?!!?!

Shaking my head so hard I pulled a muscle.

There's an alarming new diet trend taking over the internet, and much to our Disney-loving dismay, the challenge has hijacked one of our favourite childhood cartoons: Cinderella.

If you spend a lot of time on Twitter, you may have seen the 'Cinderella diet challenge' kicking about. Basically, this incredibly farfetched and incredibly unhealthy 'diet challenge' involves calculating your BMI and trying to get it down to the same number as Cinderella.

Yes, Cinderella.

As in, the fictional cartoon character.

Of course, Cinderella doesn't have an actual BMI. She's a cartoon character for f*cks sake. But someone on the internet claims to have figured out what her BMI would be if she were a person. And it's dangerously low — 18 to be specific.

It sounds crazy, but for the Twitter users who have jumped on board, the challenge is very damaging to their overall health and self-esteem. For anyone who has suffered from disordered eating in the past, it could also be quite triggering.

Christine Morgan, CEO of The Butterfly Foundation, has a few choice words to say about the challenge. "We have now plummeted to the depth where we're not just looking at a highly sculptured human image that we're trying to hold up as an ideal that 99 per cent of us can't reach – we've now resorted to going to a fictional cartoon," Morgan tells Cosmo, "and putting in a calculation which takes us to the borderline of being medically diagnosable for a clinical eating disorder."

"When are we going to actually realise there is no merit whatsoever in trying to achieve a body size or shape that isn't conforming to our genetic shape or size?" she continues. "It's crazy. We cannot override our genetics."

Cinderella is a great movie. It really is. Can we just leave it at that and put this diet challenge where it belongs: in the bin.
