据报道，进食速度与身体成分和形状有关。人们对客观评估的进食速度与身体成分和形状之间的关系知之甚少。这项研究探讨了客观和主观评估的进食速度与身体成分和形状之间的关系。本文测定了84名女大学生的体成分和形态指标：体质量、相对体脂质量（%Fat）、体质量指数（BMI）、腰围、腹围和臀围。在测量身体成分和形状后，受试者食用了174千卡的鲑鱼饭团。通过观察受试者面部的录像带记录来测量以下咀嚼变量：每次咀嚼的次数、咀嚼的总次数、总进餐时间、咀嚼次数和咀嚼速率。受试者根据他们自己对实际进食速度的主观评估分为三组（快速，中等和缓慢）。在进食速度的客观评估中，咀嚼的总次数和总进餐时间与体重、%脂肪、BMI和腰围、腹围和臀围呈显著负相关。在主观进食速度评估中，快速进食组的体重、%脂肪、BMI和腰、腹、臀围均大于慢速进食组。客观和主观评估的进食速度都与身体成分和形状有关。目前的研究支持快速进食可能与体重和/或脂肪量的增加有关。
Eating speed reportedly relates to body composition and shape. Little is known about the relationship between the objectively assessed eating speed and the body composition and shape. This study examined relationships between eating speed as assessed both objectively and subjectively, and body composition and shape. The following variables of body composition and shape were measured in 84 female college students: body mass, relative body fat mass (%Fat), body mass index (BMI), and circumferences of the waist, abdomen and hip. After measuring the body composition and shape, subjects consumed a 174-kcal salmon rice ball. The following chewing variables were measured by observing videotape recordings of the subjects' faces: number of chews per bite, total number of chews, total meal duration, number of bites, and chewing rate. The subjects were categorized into three groups (fast, moderate and slow) according to their own subjective assessments of the actual eating speed. In objective assessments of the eating speed, the total number of chews and the total meal duration were significantly negatively correlated with the body mass, %Fat, BMI, and circumferences of the waist, abdomen and hip. In subjective eating-speed assessments, the body mass, %Fat, BMI, and circumferences of the waist, abdomen and hip were greater in the fast eating group than in the slow eating group. Both the objectively and subjectively assessed eating speeds are related to the body composition and shape. The present study supports that fast eating may relate to gains in body mass and/or fat mass.
