Chinese woman, 31, faces lifelong walking issues after water-only diet cuts 20kg in weeks

A woman from central China undertook a fasting regimen for half a month and lost 20kg, but ultimately suffered from a serious brain disorder from which she may never fully recover.The 31-year-old woman from Henan province, who wishes to remain anonymous, was recently reported by local media to have developed walking difficulties and memory deterioration after consuming nothing but water for 15 consecutive days.Standing at 160 cm tall, the woman, previously weighing 70kg, managed to shed 20kg in mere weeks due to her extreme diet.According to neurologist Sun Guifang from The First Affiliated Hospital of Zhengzhou University, the woman was diagnosed with Wernicke’s encephalopathy, a severe brain disorder resulting from a deficiency of essential vitamins and folic acid.This medical condition can lead to symptoms such as confusion, balance issues while walking, eye movement disorders, and memory impairment.The extreme diet resulted in confusion, balance issues, eye movement disorders, and memory impairment.

Both dieting and fasting can pose serious risks to health.The woman informed Sun that she was practising “bigu,” a Taoist fasting technique rooted in the belief that one can achieve transcendence and immortality by subsisting solely on qi – the vital energy circulating throughout the universe.Bigu, which translates literally to “grain avoidance,” is believed to have originated before the Qin dynasty (221 BC–206 BC).While modern approaches to weight loss advocate for a diet rich in minimally processed foods, low in sugar and fat, and high in protein, many individuals still support bigu as an effective method for weight loss and detoxification.On one popular social media platform, the hashtag #bigu boasts 360 million views and has sparked 2.4 million discussions.Some individuals shared experiences of losing over 10kg after consuming only water and vitamin supplements for a month.Experts emphasise that healthy weight loss is best achieved through a balanced diet and regular physical activity, not severe caloric restriction.

She also experienced life-threatening hypokalemia.There is a growing call to ban such content.One commenter stated: “Bigu is not traditional culture but an extremely unhealthy lifestyle.”Another remarked: “I find these individuals ruthless. I can’t even skip one meal in a day.”
