The gastric and intestinal handling of a standard liquid 300-ml meal (0.89 kcal/ml) was examined in 10 healthy, non-obese subjects by a quantitative multiple-indicator dilution technique. Such a meal contains about one-tenth of the daily energy requirements. The heavier the subject the more energy was transferred from the stomach to the intestine during the first 80 minutes after taking the meal. A high body weight was also associated with a rapid transit through the proximal 70 cm of intestine and the passing of a substantial part of the meal calories to the lower intestine. These circumstances favour a fast incorporation of fed calories. In subjects with lower body weights eneryg was delivered more slowly from the stomach. The absorbed an equal amount of energy in the proximal intestine as did the heavier subjects, but during the longer transit times. The percentage absorption in the investigated segment was therefore higher.
通过定量多指标稀释技术，对10名健康、非肥胖受试者的标准300毫升液体餐（0.89千卡/毫升）的胃肠处理情况进行了检查。这样一顿餐约含每日能量需求的十分之一。受试者体重越重，用餐后前80分钟内从胃转移到肠道的能量就越多。高体重还与食物在近端70厘米肠道的快速转运以及大部分餐食热量传递至下肠道有关。这些情况有利于快速摄入进食的热量。体重较低的受试者，能量从胃中释放得更慢。他们在近端肠道吸收的能量与体重较重的受试者相同，但转运时间更长。因此，在被研究节段的吸收百分比更高。
