Once upon a time, a Japanese weight-loss trend called the ‘Cinderella diet’ went viral, and created a Twitter storm.

The controversial and unhealthy fad tells people how to calculate their ‘Cinderella goal weight’, so that they can look like the fictional character.

The fictional princess is being used as a controversial staple for ‘weight goals’.

The Cinderella Diet (sometimes called the Cinderella weight challenge) is expanding from Japan to the United States. The Cinderella Diet is basically what it sounds like: Dieting to achieve the same proportions as the fictional Disney character. To find that “magical” weight, you have to measure your height in meters, square it, then multiply by 18. This will spit out your “ideal” weight in kilograms, so you would need to multiply this number by 2.2 to get the figure in pounds.

According to the BMI (Body Mass Index) — which is shitty at correlating health and weight, but still the most popular method used — the Cinderella weight is either fully underweight, or on the border.

For example, a 5’4″ woman with a Cinderella weight of 108 pounds would have a BMI of 18, which is veering between underweight and “normal” weight.

Plus, health looks different on everyone. Saying that one weight is a “goal” weight is terrifying, incorrect, and beyond messed up.

Is the Cinderella diet dangerous?

Those who have a BMI of 18.5-25 are considered to be a healthy weight so the Cinderella diet puts people below this healthy range.

Many medical professionals believe that having a BMI that’s too high or low can increase your risk of health problems, including heart disease, stroke and type 2 diabetes.

Many believe these fad diets, such as the new Cinderella trend, are a big red warning for disordered eating symptoms.

Plugging a few heights into the formula gives us the following combinations:

● 165 centimeters = 49 kilograms

● 170 centimeters = 52 kilograms

● 175 centimeters = 55 kilograms

● 180 centimeters = 58 kilograms

If those sound like especially low body weights, it might be because they’re actually 18 percent lighter than the weights recommended for women of that height by the Japan Medical Association. In other words, even by Japan’s already slim baseline (relative to other societies), the Cinderella weight reflects a remarkably light build. The Cinderella weight also works out to a Body Mass Index of 18, whereas proponents of BMI as a health metric maintain that anything under 18.5 is too low.

What is the Cinderella diet?

In a time where there is an increased focus on healthy eating, healthy living, and body acceptance/positivity, there has come along a diet that seemingly puts those that try it at risk. This diet, dubbed The Cinderella Diet, is dieting to achieve the same proportions as the fictional Disney character.
