小的饮食行为变化被认为比传统的行为减肥研究中使用的更大的变化更可行。然而，目前还不清楚超重的黑人和西班牙裔成年人在低收入城市环境中是否经历了可行的小变化，以及可能影响可行性的因素。参与者在为期12周的试点减肥干预的经验进行了定性探讨，以确定在这一人群中进行小的饮食行为改变的可行性。干预后（69%保留），半结构化访谈46名男性和女性（平均年龄51，50%非西班牙裔黑人，43%西班牙裔）显示，使小的饮食变化是一个过程，由参与者的自我和人际饮食环境形成。参与者通过适应小变化策略，导航饮食环境和谈判家庭饮食习惯来应对个人和人际饮食环境的挑战。研究结果强调了即使是微小的饮食行为变化也需要适应，导航和谈判日常生活中复杂的饮食环境。这些发现被用来改善随后的试验，并强调可行性研究的重要性，为社区试验提供信息。调查结果还增加了对背景挑战的理解，以及在低收入少数民族人口中实施小变化所需的技能。
Small eating behavior changes are proposed as more feasible to achieve and maintain than larger changes used in traditional behavioral weight loss studies. However, it is unclear whether overweight Black and Hispanic adults in a low-income urban setting experience small changes as feasible and what might influence feasibility. Participants' experiences in a 12-week pilot weight loss intervention were explored qualitatively to determine the feasibility of making small eating behavior changes in this population. After the intervention (69% retention), semi-structured interviews with 46 men and women (mean age 51, 50% Non-Hispanic Black, 43% Hispanic) revealed that making small eating changes was a process shaped by participants' intrapersonal and interpersonal eating environments. Participants responded to intrapersonal and interpersonal eating environmental challenges by adapting small change strategies, navigating eating environments, and negotiating household eating practices. Findings highlight how even small eating behavior changes called for adaptation, navigation, and negotiation of complex eating environments in daily life. These findings were used to improve the trial that followed and underline the importance of feasibility studies to inform community trials. Findings also add to understanding of contextual challenges and the skills needed to implement small changes in a low income, ethnic minority population.
