Purpose. The present study seeks to identify the efficacy of connected weight management programs focusing on studies measuring the efficacy of the programs. Design/ Methodology/ Approach. A comprehensive literature review was undertaken examining 6 databases to identify studies reporting the use of digital devices to address diet. Fifteen empirical studies were analyzed to examine the effectiveness of digital devices in improving weight loss. Findings. Digital devices supporting weight loss programs have evolved rapidly over the last 15 years, from reminders using the short message system to self-quantification through mobile applications. Although they are less effective than individualized face-to-face programs, many programs mediated by communication technologies have proven effective for weight loss. Research limitations /implications. The literature review is limited to studies that have scientifically evaluated the (potential) weight loss associated with intervention. This review could be put into perspective with other complementary research, in particular qualitative research aimed at exploring participants' motivations to use (or not) digital devices to lose weight. Social implications. Given their low cost and the size of the overweight population, it appears that public health policies could integrate digital devices more strongly in their efforts to combat obesity. Social marketing can add its expertise to medical-based programs which in return bring their need for more quantitative evaluation of the efficacy of the interventions. Originality / Value. To our knowledge, this literature review is the first to comprehensively review the effectiveness of digital devices for weight loss. This review makes it possible to identify some strong points of digital devices and to point out their limits.

使用数字设备帮助人们减肥：系统综述

目的。本研究旨在确定连接体重管理计划的功效，重点是评估该计划功效的研究。设计/方法论/方法。对6个数据库进行了全面的文献综述，以鉴定报告使用数字设备解决饮食问题的研究。分析了十五项实证研究，以检验数字设备在减轻体重方面的有效性。发现。在过去的15年中，支持减肥计划的数字设备已经迅速发展，从使用短信系统的提醒到通过移动应用程序进行自我量化。尽管它们不如个性化的面对面程序有效，但许多由通讯技术调解的程序已被证明对减肥有效。研究局限/含义。文献综述仅限于科学评估与干预相关的（潜在）减肥的研究。可以与其他补充研究（尤其是旨在探索参与者使用（或不使用）数字设备减轻体重的动机的定性研究）的角度对这篇评论进行深入探讨。社会影响。鉴于其成本低廉和超重人群的规模，公共卫生政策似乎可以在抵抗肥胖的努力中更牢固地整合数字设备。社会营销可以将其专业知识添加到基于医疗的计划中，这反过来又带来了他们对干预效果进行更定量评估的需求。创意/价值。据我们所知，这篇文献综述是首次全面综述数字设备减肥的有效性。通过这次审查，可以确定数字设备的一些强项并指出其局限性。
