weight-loss product advertisements

The data comprises 40 advertisements for weight-loss products posted on the Chinese WeChat platform, spanning the period from October 2021 to September 2025. These ads were systematically gathered using the keyword “减肥产品” (“jianfei chanpin” in Pinyin or “weight-loss products” in English). To ensure the data’s representativeness and validity, we included only those advertisements with a commercial intent, i.e., those that promoted a specific weight-loss product by emphasizing its name, claimed benefits, purchase links, and/or consumer reviews. Additionally, duplicate ads were removed to avoid sampling bias. These advertisements featured both textual and visual elements.
