DESCRIPTION (provided by applicant): Self-monitoring has been described as the "cornerstone of the behavioral treatment of obesity" . Consistent self-monitoring of energy intake is associated with improved dietary adherence and weight loss and maintenance. The problem is that individuals are notoriously bad at self-monitoring their intake and suffer from an underreporting bias. The significance of the proposed work is that it will make a low-cost intake monitoring device widely available for use in behavioral weight loss treatment and research. Our innovative intake monitoring method uses sensors embedded into a watch-like device to automatically track wrist motion to count bites and provide intake feedback during a meal, allowing individuals to self-monitor intake anywhere and anytime. In Phase 1, the method was shown to accurately count bites across a wide variety of foods, utensils and subject demographics, and to provide an unbiased intake measurement. Additional studies show people will use the device long-term and prefer our method over a manual method. The proposed work will continue to improve the bite counting method by adapting to varying eating rates, develop a self-managed bite count based weight loss protocol, and perform an independent test of the protocol.

描述（由申请人提供）：自我监控被描述为“肥胖行为治疗的基石”。持续自我监测能量摄入与改善饮食依从性以及减肥和维持体重有关。问题是，众所周知，人们不善于自我监控自己的摄入量，并且存在漏报偏差。这项工作的意义在于，它将使得低成本的摄入监测装置广泛用于行为减肥治疗和研究。我们创新的摄入量监测方法使用嵌入手表式设备中的传感器来自动跟踪手腕运动以计算叮咬次数并在进餐期间提供摄入量反馈，使个人能够随时随地自我监测摄入量。在第一阶段，该方法被证明可以准确地计算各种食物、器具和受试者人口统计数据的叮咬次数，并提供公正的摄入量测量。其他研究表明，人们会长期使用该设备，并且比手动方法更喜欢我们的方法。拟议的工作将通过适应不同的进食率来继续改进咬计数方法，开发基于自我管理咬计数的减肥方案，并对该方案进行独立测试。
