The aim of this study is to assess the influence of body image on consumers' willingness to pay (WTP) for potato chips carrying nutritional claims among obese and non-obese people. About 309 non-clinical individuals participated in a Real Choice Experiment. They were recruited by a company and grouped in: (i) non-obese with good body image; (ii) non-obese with body image dissatisfaction; (iii) obese with good body image; (iv) obese with body image dissatisfaction. Results indicate differences in consumers' willingness to pay among consumer groups. Body image dissatisfaction of normal people did not influence the WTP for healthier chips. Obese people with body image dissatisfaction were willing to pay more for healthier chips (i.e., low-salt content potato chips) than normal ones with body image dissatisfaction. Examining the role of knowledge in the light of how this could impact on body image is relevant to improve the health status of individuals and their diet. Knowledge about nutrition could improve the body image of obese people.
本研究的目的是评估身体形象对肥胖和非肥胖人群购买带有营养声明的薯片的支付意愿（WTP）的影响。约309名非临床个体参与了一项真实选择实验。他们由一家公司招募，并分为：（i）身体形象良好的非肥胖者；（ii）对身体形象不满意的非肥胖者；（iii）身体形象良好的肥胖者；（iv）对身体形象不满意的肥胖者。结果表明不同消费者群体之间的支付意愿存在差异。正常人群对身体形象的不满意并不影响其对更健康薯片的支付意愿。与身体形象不满意的正常人群相比，对身体形象不满意的肥胖人群愿意为更健康的薯片（即低盐含量薯片）支付更多费用。鉴于知识如何影响身体形象，研究知识的作用对于改善个体的健康状况及其饮食具有重要意义。关于营养的知识可以改善肥胖人群的身体形象。
