本文從身材審美觀的變化與胖瘦健康觀念的轉變切入，藉由報紙的報導內容探討 1950 年到 1980 年間臺灣減肥觀念的形成及減肥群眾的拓展。戰後初期，臺灣的女性身體審美觀雖然傾向「瘦」，但卻不排斥豐滿的身材。但在西方審美的影響下，臺灣女性審美觀出現「以瘦為美」的情況，並且只崇尚「瘦」的身材，女性的身體曲線美出現具體的數字比例。就胖瘦的健康概念而言，戰後初期臺灣一般民眾對於胖的觀感是正面的，認為胖是有福氣，身體是健康的，但在西方醫學不斷指出肥胖對身體的負面影響後，肥胖不再是福氣的代表，而是罹患疾病的危機。隨著審美觀念及健康觀念的轉變，減肥群眾不斷地擴增，報紙上大多是知名人物如政治人物、演藝人員及高社經地位者減肥的報導。這些高知名度人物的生活，常受到一般民眾檢視、仿效，其減肥的新聞報導也推動臺灣民眾對減肥觀念的接納與模仿。

This paper explored the change of aesthetics and healthy bodyweight from the coverage of the newspaper published in Taiwan between 1950 to 1980 to discuss the formation of weight loss and the expansion of weight-loss people. In the early years after the war, Taiwan's feminine aesthetics tended to be ‘thin', but did not reject the fullness of the body. However, under the influence of Western aesthetics, Taiwan's feminine aesthetics appeared to be ‘The thinner, the more beautiful.' The ratio of feminine slim figure showed that female in Taiwan only advocated thin body. On the concept of bodyweight, Taiwanese had a positive opinion toward obesity, that chubby body was blessed and healthy in the early years after the war. Nevertheless, western medicine has pointed out that the adverse effects of obesity on the body. Obesity was not the representative of the blessing, but the risk of disease. With the change of aesthetic and health concepts, people who lost weight expanded. The weight-loss news of the well-known figures such as politicians, entertainers and people with high social status, were reported on the newspaper. The news also promoted Taiwanese to accept and imitate high-profile people to lose weight.
