Expert panels and governmental guidelines now recommend that obese persons seek modest (i.e., "reasonable") reductions in body weight rather than striving for "ideal" weights. Little is known, however, about patients' views of what is a "reasonable" weight loss. This study assessed patients' goals, expectations, and evaluations of various outcomes before, during, and after 48 weeks of treatment. Before treatment, 60 obese women (99.1 +/- 12.3 kg; body mass index of 36.3 +/- 4.3 kg/ m2) defined their goal weight and 4 other weights: "dream weight"; "happy weight"; "acceptable weight"; and "disappointed weight." Goal weight averaged a 32% reduction in body weight. A 17-kg weight loss was defined as disappointed; a 25-kg loss, was acceptable. After 48 weeks of treatment and a 16-kg weight loss, 47% of patients did not achieve even a disappointed weight. These data illustrate the dramatic disparity between patients' expectations and professional recommendations and the need to help patients accept more modest weight loss outcomes.
专家小组和政府指南现在建议肥胖者适度（即“合理”）减轻体重，而不是追求“理想”体重。然而，对于患者而言，什么是“合理”的体重减轻，人们知之甚少。本研究评估了患者在治疗48周之前、期间和之后的目标、期望以及对各种结果的评价。治疗前，60名肥胖女性（体重99.1±12.3千克；体重指数为36.3±4.3千克/平方米）确定了她们的目标体重以及其他4种体重：“理想体重”；“满意体重”；“可接受体重”；以及“失望体重”。目标体重平均为体重减轻32%。体重减轻17千克被定义为失望；减轻25千克为可接受。经过48周治疗且体重减轻16千克后，47%的患者甚至未达到失望体重。这些数据表明了患者期望与专业建议之间的巨大差异，以及帮助患者接受更适度的体重减轻结果的必要性。
