The regularity of eating, together with other nutritional factors, is one of the important determinants of health. According to previous studies, it is not clear if a greater fluctuation in energy intake is associated with higher body fat and weight gain, or if the weight of people is stable despite these fluctuations in the energy intake. The aim of the study was to verify if a higher variability in the energy intake each day of the week is related to the amount of body fat and other anthropometric parameters. A total of 220 (151 women, 69 men) individuals of Czech Caucasian origin with a BMI of 18.3-58 kg/m, aged 21.7-79.7 were included in the study. Selected anthropometric characteristics were measured using a bioelectrical impedance analysis. 7-day food records were completed and analyzed using nutritional software. The measured values were statistically evaluated by multiple linear regression analysis. The results of the multiple linear regression showed the statistically significant dependence of the percentage of body fat (p<0.01), BMI (p<0.01), and waist circumference (p<0.05) on the relative variability of the daily energy intake. The results of our study suggest that people with more regular energy intake also have better anthropometric parameters related to their cardiometabolic health.
进食规律连同其他营养因素，是健康的重要决定因素之一。根据既往研究，目前尚不清楚能量摄入波动较大是否与体脂增加和体重增加有关，或者尽管能量摄入波动，人们的体重是否保持稳定。本研究旨在验证每周每日能量摄入变化较大是否与体脂量和其他人体测量参数有关。 研究共纳入 220 名（151 名女性，69 名男性）具有 18.3-58kg/m² BMI 的捷克白种人，年龄为 21.7-79.7 岁。采用生物电阻抗分析法测量选定的人体测量特征。使用营养软件完成并分析 7 天的食物记录。通过多元线性回归分析对测量值进行统计学评估。 多元线性回归的结果显示，体脂百分比（p<0.01）、BMI（p<0.01）和腰围（p<0.05）与每日能量摄入的相对变异性呈统计学显著相关性。 本研究结果表明，能量摄入更规律的人群其与心脏代谢健康相关的人体测量参数也更好。
