Obese people are mostly unable to maintain successful weight loss after the end of a dietary change. One reason is that conventional weight reduction concepts neglect physiological hunger and satiety perception, leading to a relapse to previous eating habits on the long run. We examined the long-term efficacy of a psychological smartphone weight loss program, which avoids any dietary instructions and aims at relearning of satiety perception. Parameters of body weight alterations and psychological features, for example, satiety perception, food cravings, and emotional eating, were explored in a nonrandomized experimental study comprising 75 obese participants. Measurements occurred at baseline, two times during program application, as well as at 6- and 12-month follow-up. Participants displayed significant weight loss during the entire study period (p = .029) and showed an improved body composition at the 6-month follow-up (p = .018). These effects were associated with increased satiety perception, as well as reduced food cravings, and emotional eating habits. Notably, all improvements in measured parameters significantly sustained between the end of the program and the 12-month follow-up (p < .005 for all). Psychological relearning of satiety perception may outclass dietary approaches in terms of long-term efficiency.
肥胖人群在结束饮食改变后，大多无法保持成功的体重减轻。原因之一是传统的减重概念忽略了生理饥饿感和饱腹感感知，导致长期内恢复到以前的饮食习惯。我们研究了一种避免任何饮食指导、旨在重新学习饱腹感感知的心理智能手机减肥计划的长期效果。在一项非随机实验研究中，我们调查了 75 名肥胖参与者的体重变化参数和心理特征，例如饱腹感感知、食物渴望和情绪化进食。测量在基线时、计划应用期间两次以及 6 个月和 12 个月随访时进行。参与者在整个研究期间体重显著减轻（p=.029），并且在 6 个月随访时体成分得到改善（p=.018）。这些效果与饱腹感感知增加以及食物渴望和情绪化进食习惯减少有关。值得注意的是，所有测量参数的改善在计划结束和 12 个月随访之间均显著持续（所有 p<.005）。饱腹感感知的心理再学习在长期效果方面可能优于饮食方法。
