Replication Data for Comparison of low calorie-standard protein or high protein diet on body composition,malondialdehyde and glutathione, and hs-CRP level

This is an open-randomized clinical trial comparing the effect of two low calorie diet differ mainly in the protein composition, namely high protein diet (22-30 percent of overall caloric intake) and standard protein diet (12-20 percent) on body composition, inflammation, and oxidative stress parameters. Body composition paramteres were measured using bioimpedance analysis methods with the Tanita device. The parameters were body weight (kg),body mass index (kg/m2), fat mass (kg), muscle mass (kg), fat mass percentage, and muscle mass percentage. The inflammation marker used were high sensitivity C-Reactive Protein (hs-CRP). Serum malondialdehyde and glutathione were used as oxidative stress markers.本研究为一项开放随机临床试验，对比两种主要差异在于蛋白质构成的低热量饮食对人体成分、炎症及氧化应激指标的影响。两种饮食方案分别为高蛋白饮食（占每日总热量摄入的22%~30%）与标准蛋白饮食（占12%~20%）。 人体成分指标采用生物电阻抗分析法，借助Tanita设备完成检测，具体检测指标包括体重（单位：kg）、身体质量指数（单位：kg/m²）、脂肪量（kg）、肌肉量（kg）、脂肪百分比以及肌肉百分比。 本次研究选用的炎症标志物为高敏C反应蛋白（high sensitivity C-Reactive Protein，hs-CRP）；血清丙二醛与谷胱甘肽则作为氧化应激标志物用于检测。
