The eating behaviour of 19 normal weight males, 19 obese males, 19 normal weight females and 19 obese females was measured by means of VIKTOR, our version of the universal eating monitor. The total food intake, the duration of consumption, the rate of consumption, the relative rate of consumption and the subjective motivation to eat were measured during five homogenous lunch meals to analyse how these variables were related to body weight or to sex. Furthermore, the stability of the eating characteristics over the five eating occasions were tested with pre-defined criteria of stability. The predictive validity of the variables measuring subjective motivation to eat and forthcoming food intake was also tested.
Men ate more food than women; normal weight men by eating for a longer time and obese men by eating faster. Females did not slow down the eating rate towards the end of the meals as much as males did. The obese subjects described themselves as having less motivation to eat prior to meals than normal weight subjects.
Total stability, i.e. both relative and absolute stability, for all subjects was present for the eating variables intake of food and eating rate. Of the variables measuring subjective motivation to eat (desire to eat, hunger, fullness and prospective consumption) on visual analogue scales, only the variables desire to eat and prospective consumption predicted forthcoming food intake.
采用我们版本的通用饮食监测仪VIKTOR，测量了19名正常体重男性、19名肥胖男性、19名正常体重女性和19名肥胖女性的饮食行为。在五顿同质午餐期间，测量了食物总摄入量、进食持续时间、进食速度、相对进食速度和主观进食动机，以分析这些变量与体重或性别之间的关系。此外，还根据预先定义的稳定性标准，测试了五种进食场合下饮食特征的稳定性。还测试了测量主观进食动机和即将到来的食物摄入量的变量的预测效度。
男性比女性进食更多；正常体重男性进食时间更长，肥胖男性进食速度更快。女性在进餐接近尾声时不像男性那样减慢进食速度。肥胖受试者表示，与正常体重受试者相比，他们在餐前的进食动机较小。
对于所有受试者，食物摄入量和进食速度这两个饮食变量都呈现出完全稳定性，即相对稳定性和绝对稳定性。在视觉模拟量表上测量主观进食动机（进食欲望、饥饿感、饱腹感和预期摄入量）的变量中，只有进食欲望和预期摄入量这两个变量能够预测即将到来的食物摄入量。
