When stress or anxiety hits, and food is your go-to response, you’re probably tempted to eat something comforting. But, very often, those comfort foods are the very foods that can contribute most to weight gain because they tend to be high in fat and sugar. You’re more likely to grab a doughnut, a container of ice cream, or anything chocolate while experiencing negative emotions than you are to wolf down a mixed-greens salad.
当压力或焦虑来袭时，食物是你的首选，你可能会想吃些安慰的东西。但是，通常情况下，这些安慰性食物是最容易导致体重增加的食物，因为它们往往是高脂肪和高糖的。当你经历消极情绪时，你更有可能吃甜甜圈、冰淇淋或任何巧克力，而不是狼吞虎咽地吃一份混合蔬菜沙拉。
While increased physical activity may help burn those excess calories, new research suggests that a moderate-to-vigorous exercise routine also helps prevent overeating to begin with, by reducing the effects of negative emotions on your eating habits. In a small, multilocation study performed at University of Southern California in Los Angeles, Warren Alpert Medical School at Brown University in Providence, University of South Carolina in Columbia, and University of Pittsburgh, researchers assessed the physical activity of 55 overweight and obese women before and after they participated in a three-month online behavioral weight loss program.
虽然增加体育锻炼可能有助于燃烧这些多余的卡路里，但新研究表明，适度到剧烈的锻炼也有助于从一开始就防止暴饮暴食，减少负面情绪对饮食习惯的影响。在洛杉矶的南加州大学、普罗维登斯的布朗大学的沃伦·阿尔珀特医学院、南卡罗来纳大学哥伦比亚分校和匹兹堡大学进行的一项小规模、多地点的研究中，研究人员对55名超重和肥胖女性参加为期三个月的在线行为减肥项目前后的身体活动进行了评估。
Using ecological momentary assessment for two weeks before the online intervention and for two weeks afterward, the researchers tracked participants’ exercise and eating habits in real time, as the women went about their lives in their everyday, real-world environments. In the final assessment, the researchers found that when the women momentarily experienced higher than usual levels of anxiety or stress, they were less likely to overeat or turn to tempting foods if they had recently increased their levels of exercise as compared to their normal level. While more and bigger studies are necessary to determine whether or not this practice can have a positive effect on weight-loss goals, this research suggests that moderate-to-vigorous exercise has a direct effect on the ability to regulate one’s eating habits during times of stress or anxiety.
通过在线干预前两周和在线干预后两周的生态瞬时评估，研究人员实时跟踪参与者的运动和饮食习惯，这些女性在日常的真实环境中生活。在最后的评估中，研究人员发现，当这些女性暂时经历了高于正常水平的焦虑或压力时，如果她们最近的锻炼水平比平常强度更大，她们就不太可能吃得过多或转向诱人的食物。虽然需要更多更大规模的研究来确定这种做法是否能对减肥目标产生积极影响，但这项研究表明，中高强度的锻炼对一个人在压力或焦虑时调节饮食习惯的能力有直接影响。
