Doctors Warn Against Copying Mai Lin's Seven-Month, 20-Kilogram Weight Loss
The reality-TV figure Mai Lin says she went from about 65 kilograms to 46 in seven months — and a top-tier hospital's weight-management clinic rendered the verdict Chinese social media was waiting for: the pace is compliant, the target too aggressive, and the plan not for ordinary people to imitate.
Mai Lin — the reality-television figure whose marital show "See You Again" made her one of the most discussed, and most criticized, women on the Chinese internet — has a new claim to attention: a body transformation. In a livestream clip she said she stands 155 centimeters and, over roughly seven months, went from about 65 kilograms to 46. Before-and-after images flooded Weibo under the tag #Mai Lin lost 40 jin in seven months#, the jin — half a kilogram — underlining the arithmetic. She also admitted her weight had rebounded at points, and urged viewers not to fall into "body anxiety."
On Friday the claim collided with an institution. Qianjiang Video put it to Wang Chenfang, deputy director of the weight-management clinic at Zhejiang Zhongshan Hospital, a top-tier hospital in Hangzhou. Her verdict was double-edged. If the loss really came from gradual diet and exercise, with no hair loss, missed periods or persistent fatigue, the pace — inside the clinical guideline of 0.5 to 1 kilogram a week — was "compliant." But the total, she said, was too large for Mai Lin's starting point: a goal that is "aggressive" rather than exemplary. Clinical standards, she stressed, are written for overweight and obese patients, not for someone near the bottom of the healthy range.
Her worksheet made the danger concrete. Take a 65-kilogram person: lose 14 kilograms and they land at a healthy BMI of about 21.2; lose 28 and they arrive at 15.4, clinically underweight. She listed what crash dieting actually costs — heavy muscle loss, a slower basal metabolism, loose skin, a sharply higher risk of gallstones — and flagged the other direction too: weight falling fast without deliberate dieting can signal thyroid disease, diabetes or gut disorders, and warrants a hospital visit. The "seven months, 40 jin" formula, she said, is a linear extrapolation that must not be mechanically applied to anyone.
The fascination is the story's real engine. Mai Lin's transformation is the latest entry in a celebrity diet cycle that Chinese health discourse has spent years pushing back against — the injectable era already produced its own reckoning, with a follow-up on what happened to the semaglutide generation a year later documenting the rebound — and the beauty standard underneath drew its own protest when a photo studio announced it would serve only customers under 132 pounds. Mai Lin, notably, joined that chorus herself: the same stream that showed her new figure carried the advice that no one should treat it as a template.
Her advice to the ordinary viewer was to treat another person's timeline as noise: plans have to be built on one's own height, starting weight and metabolism, not on a livestream's before-and-after. Whether that survives contact with the comment section — where users were already praising her "confidence" and her new look — is the question the next livestream will answer.
