Health AI Ant Afu data reveals that during the holiday period from September 25 to October 6, among the netizens nationwide participating in Afu's "Scientific Weight Loss of 100 Million Jin" campaign, 600,000 people collectively gained over 1 million jin. Among them, more than 100,000 gained over 3 jin.

From October 4 to 7, the statistical data on the weight loss activity page of the Ant Afu app had already shown "Yesterday's National Weight Gain" for four consecutive days, with October 7 showing a single-day net weight gain of 34,700 jin nationwide, prompting netizens to joke that the weight loss cause had entered a "retreat." During the long holiday, netizens in Zhejiang gained 113,000 jin, ranking second among all provinces nationwide, just behind Guangdong's 136,000 jin. Hangzhou ranked second among all cities nationwide, with a gain of 48,000 jin. Some netizens remarked that whether a place is a culinary powerhouse can be seen from the jin gained.

Gaining Three Jin Every Festival? Hangzhou Netizen: That's Conservative

"I lost 2 jin before leaving, but when I stepped on the scale after coming back, my weight loss contribution turned into -2 jin." Hangzhou white-collar worker Ms. Li told reporters that she had previously participated in Afu's 21-day weight loss check-in campaign and went back to her hometown during the Mid-Autumn and National Day holiday. "The food at home was too delicious, and it felt rude not to pick up chopsticks at friends' gatherings, plus I stopped exercising." She said she was still relatively controlled, but her relative Old Zhang posted on social media after the holiday: "Three jin gained every festival, happiness doubled by three kilograms!" It turned out that Old Zhang's family recently had a big happy event—his daughter's wedding. Before and after the wedding, relatives and friends came in waves, and dinner parties and late-night snacks continued non-stop. Last night, Old Zhang stepped on the scale and found he was a full 6 jin heavier than before the holiday. "I was startled!" He quickly opened Afu to ask, and thankfully Afu said most of those 6 jin were water and food residue, suggesting he first restore regular meals, drink more water, and eat light for a few days, and it would come back down in about a week. Old Zhang breathed a sigh of relief: "I'm happy about my daughter's wedding, and I accept gaining weight from eating, but after the holiday, I still have to face reality."

Afu data shows that among the people who gained weight during the holiday, about 270,000 had fluctuations within 3 jin, with most netizens' weight management "still controllable"; about 90,000 gained 3 to 6 jin, already exceeding the folk benchmark of "gaining three jin every festival"; and over 10,000 gained more than 6 jin.

Is Holiday Weight Gain an Objective Pattern? Expert: Don't Rush to Diet

The number on the scale going up doesn't necessarily mean your willpower has failed. Regarding "holiday fat," scientists have already studied it. Professor Yu Xiaohua and others from the Department of Agricultural Economics and Rural Development at the University of Göttingen in Germany found in 2020 that Chinese adults gained an average of 1.56 kilograms, or about three jin, during the 7-day National Day holiday. Sounds scary, but don't panic—this extra weight won't stay forever. After about two weeks, it may shrink to 0.97 kilograms; after another month, only 0.49 kilograms remain. Weight loss science blogger and Deputy Director Han Xiaodong of the General Surgery Department at Shanghai Sixth People's Hospital stated that it's easy to gain weight during holidays, closely related to diet, exercise, and daily routines. During holidays, there are more gatherings and eating out, with higher intake of high-sugar, high-oil, and high-salt foods, while reduced exercise and disrupted routines lead to weight gain. After the holiday, weight can be restored through diet control and exercise.
