在目前的三个实验中，进行了测试，以查看摄入后因素是否在由3%葡萄糖和0.125%糖精溶液的组合引起的过量饮酒中起作用。第一个实验表明，当向大鼠提供葡萄糖+糖精（G+S）溶液时，每日总热量摄入量显著增加，从食物中摄取的热量比例降低。尽管饮用G+S会导致饮食发生变化，但实验2比较了不同浓度的葡萄糖溶液和G+S溶液的饮用情况，证明大鼠饮用大量G+S溶液是为了味道，而不是卡路里。最后的实验比较了对各种浓度的糖精、葡萄糖或G+S溶液的偏好测试，并且显示跨G+S浓度的偏好数据在定性上与糖精偏好数据相似，并且与葡萄糖数据不同，即使操纵的是浓度中的葡萄糖的量。
In the present three experiments, tests were run to see if postingestional factors played a role in the excessive drinking elicited by the combination of 3% glucose and 0.125% saccharin solutions. The first experiment showed a marked increase in the total daily caloric intake and a decrease in the proportion of calories taken from the food when the glucose+saccharin (G+S) solution was presented to rats. In spite of this alteration of diet induced by G+S drinking, Experiment 2, which compared the drinking of various concentrations of glucose solutions and G+S solutions, demonstrated that the rat drinks these large quantities of the G+S solution for taste, not calories. The final experiment compared preference tests on various concentrations of saccharin, glucose or G+S solutions and showed that preference data across concentrations of G+S were qualitatively similar to the saccharin preference data, and different from the glucose data, even though it was the amount of glucose in the concentrations that was manipulated.
