项目摘要
DESCRIPTION (provided by applicant): The rising prevalence of obesity in the United States is believed to be due to increased exposure to adverse environmental factors, such as food portion sizes and increased dietary variety. Although decreasing portion sizes is a strategy used in weight loss programs, research has not studied the effects of decreasing dietary variety. Cross-sectional studies show a positive association between variety and body weight and in our own studies we have shown that greater reductions in the number of different snack foods (i.e. cookies, chips) consumed predicted greater decreases in overall caloric and fat intake and greater weight loss. Limiting variety may reduce intake through long-term sensory-specific satiety and/or monotony. Reducing dietary variety is a novel dietary approach with the potential to improve long-term weight loss, which has not been studied as a clinical strategy in obesity research. The objective of this application is to conduct a randomized controlled trial of a behavioral weight loss intervention limiting the number of different snack foods consumed. Two hundred overweight and obese participants will be randomized to a standard behavioral intervention (Standard) or to a standard behavioral intervention that also limits the number of different snack foods consumed (Limited Variety). Both conditions will receive an 18-month standard behavioral intervention, using behavioral techniques (i.e., self-monitoring) to change eating behaviors. Participants in the Limited Variety condition will also limit variety in snack foods to only two chosen snack foods throughout the intervention. Measures of weight, snack food consumption and hedonics, and diet satisfaction will be taken at 0, 6, 12, and 18 months. This investigation will determine: 1) if the Limited Variety condition produces greater weight loss than the Standard condition at 18 months; 2) if the Limited Variety condition consumes fewer servings and calories from snack foods than the Standard condition; and 3) if limiting snack food variety produces long-term sensory-specific satiety and/or monotony. Relevance: Experimental studies show that limiting dietary variety profoundly reduces intake. To date, there is no dietary prescription that has been tested that capitalizes on the effect of variety on intake that can be maintained. This will be the first investigation to examine methods of manipulating dietary variety that can be adhered to over time and that influence intake, weight loss, and weight loss maintenance.
描述(由申请人提供):美国肥胖症患病率的上升被认为是由于不良环境因素的暴露增加,如食物份量和饮食种类的增加。虽然减少份量是减肥计划中使用的一种策略,但研究还没有研究减少饮食种类的影响。横断面研究表明,品种和体重之间存在正相关,在我们自己的研究中,我们已经表明,不同零食(即饼干,薯条)消费数量的减少预示着整体热量和脂肪摄入量的减少以及体重的减轻。限制品种可能会通过长期的感官特异性饱腹感和/或单调感减少摄入量。减少饮食多样性是一种新的饮食方法,有可能改善长期减肥,但尚未在肥胖研究中作为临床策略进行研究。本申请的目的是进行一项限制不同零食摄入量的行为减肥干预的随机对照试验。200名超重和肥胖的参与者将被随机分配到标准行为干预(标准)或标准行为干预(限制不同零食的摄入量)。这两种情况都将接受18个月的标准行为干预,使用行为技术(即,自我监控)来改变饮食行为。在有限品种条件下的参与者还将在整个干预期间将零食的品种限制为仅两种选择的零食。将在0、6、12和18个月时测量体重、零食消耗量和快乐性以及饮食满意度。本次调查将确定:1)如果在18个月时,有限品种条件比标准条件产生更大的体重减轻; 2)如果有限品种条件比标准条件消耗更少的份量和来自零食的卡路里;以及3)如果限制零食品种产生长期的感官特异性饱腹感和/或单调感。相关性:实验研究表明,限制饮食种类会大大减少摄入量。到目前为止,还没有经过测试的饮食处方可以利用多样性对可以维持的摄入量的影响。这将是第一次调查研究操纵饮食多样性的方法,这些方法可以随着时间的推移而坚持,并影响摄入量,减肥和减肥维持。
