A number of weight loss-related reality television programs chronicle the weight loss experience of obese individuals in a competitive context. Although highly popular, such shows may misrepresent the behavior change necessary to achieve substantial weight loss. A systematic, quantitative content analysis of Seasons 10-13 (n = 66 episodes) of The Biggest Loser was conducted to determine the amount of time and number of instances that diet, physical activity, or other weight management strategies were presented. The average episode was 78.8 ± 15.7 min in length. Approximately 33.3% of an episode, representing 1,121 segments, portrayed behavioral weight management-related content. Within the episode time devoted to weight management content, 85.2% was related to physical activity, 13.5% to diet, and 1.2% to other. Recent seasons of The Biggest Loser suggest that substantial weight loss is achieved primarily through physical activity, with little emphasis on modifying diet and eating behavior. Although physical activity can impart substantial metabolic health benefits, it may be difficult to create enough of an energy deficit to induce significant weight loss in the real world. Future studies should examine the weight loss attitudes and behaviors of obese individuals and health professionals after exposure to reality television shows focused on weight loss.
一些与减肥相关的真人秀节目记录了肥胖者在竞争环境中的减肥经历。尽管此类节目非常受欢迎，但它们可能会歪曲实现大幅减肥所需的行为改变。对《超级减肥王》第10 - 13季（共66集）进行了系统的定量内容分析，以确定呈现饮食、体育活动或其他体重管理策略的时间量和次数。每集平均时长为78.8 ± 15.7分钟。一集当中约33.3%（即1121个片段）呈现了与行为体重管理相关的内容。在用于体重管理内容的时长中，85.2%与体育活动相关，13.5%与饮食相关，1.2%与其他相关。《超级减肥王》最近几季表明，大幅减肥主要通过体育活动实现，对改变饮食和进食行为的强调很少。尽管体育活动能带来显著的代谢健康益处，但在现实世界中，可能很难制造出足够的能量缺口来实现显著的体重减轻。未来的研究应考察肥胖个体和健康专业人员在接触以减肥为主题的真人秀节目后的减肥态度和行为。
