Weight loss maintenance can be difficult and ultimately unsuccessful, due to psychological, behavioural, social, and physiological influences. The present study investigated three strategies with the potential to improve weight maintenance success: daily weighing, missing an occasional meal, habitually changing high energy foods. The principal aim was to gain an understanding of attitudes to these strategies in participants who had recent experience of weight loss attempts, with or without maintenance. This was a qualitative study involving semi-structured interviews, with 20 participants aged 18-67 (twelve females), analysed using thematic analysis. Most participants disliked daily weighing and missing an occasional meal for long-term maintenance and were concerned about potential negative effects on mental health. All participants had experience of habitual changes to high energy foods and regarded this strategy as obvious and straightforward. Replacement of high energy foods was favoured over elimination. Participants preferred strategies that felt flexible, "normal" and intuitive and disliked those that were thought to have a negative impact on mental health. Further investigation is needed on whether concerns regarding mental health are well founded and, if not, how the strategies can be made more acceptable and useful.
体重维持可能很困难，最终也可能不成功，这是由于心理、行为、社会和生理等多方面的影响。本研究探讨了三种可能提高体重维持成功率的策略：每日称重、偶尔错过一餐、习惯性更换高能量食物。主要目的是了解有或没有体重维持经历的参与者对这些策略的态度，这些参与者最近曾尝试过减肥。这是一项涉及 20 名 18-67 岁参与者（12 名女性）的半结构化访谈的定性研究，使用主题分析进行分析。大多数参与者不喜欢长期维持体重的每日称重和偶尔错过一餐，并且担心这可能对心理健康产生负面影响。所有参与者都有习惯性改变高能量食物的经验，他们认为这种策略是显而易见和直接的。他们倾向于用替换高能量食物的方式，而不是消除它们。参与者更喜欢感觉灵活、“正常”和直观的策略，不喜欢那些被认为对心理健康有负面影响的策略。需要进一步研究心理健康方面的担忧是否有充分的依据，如果没有，如何使这些策略更被接受和有用。
