这项研究是为了确定摄入食物的能量含量和重量对随后的饱腹感和食物摄入量的相对影响。在3 × 3析因设计中，对9个预载荷的重量/体积和能量含量进行操作，以得到三个重量水平，250、500和750 g，以及三个能量水平0、1.26和2.51 MJ（0、300和600 kcal）。通过添加水改变重量，而通过使用酸奶和奶油改变能量水平。1.26和2.51 MJ预加载中的每一个包含27 g蛋白质和31 g碳水化合物。1.26 MJ预加载含有8 g脂肪，2.51 MJ预加载含有41 g脂肪。9个前负荷中的每一个作为午餐提供给21名女性和16名男性受试者。预负荷后两小时，受试者从自助餐中随意食用甜味和咸味小吃以及各种饮料。预负荷的重量对预负荷和自助餐之间的饥饿感和饱腹感以及自助餐期间的能量摄入（250、500和750 g预负荷后为5.34、5.05和5.04 MJ）有较小但统计学显著的影响。0和1.26 MJ之间存在较大差异，但1.26和2.51 MJ预载荷之间的效果差异不大。在0、1.26和2.51 MJ预加载后，抖振中的平均能量摄入分别为6.17、4.83和4.42 MJ。这些结果表明，食物的重量或数量会影响随后的食欲和食物摄入量，但能量的影响更强。(C)1996年学术出版社
This study was done to determine the relative effects of energy content and weight of ingested food on subsequent satiety and food intake. The weight/volume and the energy content of nine preloads were manipulated, in a 3 x 3 factorial design, to give three weight levels, 250, 500 and 750 g, and three energy levels 0, 1.26 and 2.51 MJ (0, 300 and 600 kcal). The weights were varied by the addition of water, while the energy levels were varied by using yogurt and cream. Each of the 1.26 and 2.51 MJ preloads contained 27 g of protein and 31 g of carbohydrates. The 1.26 MJ preloads contained 8 g of fat and the 2.51 MJ preloads had 41 g of fat. Each of the nine preloads was presented as a lunch to 21 female and 16 male subjects. Two hours after the preloads, subjects consumed sweet and savory snacks and various drinks ad libitum from a buffet. The weight of the preload had a small but statistically significant effect on feelings of hunger and satiety between preload and buffet, and on energy intake during the buffet (5.34, 5.05 and 5.04 MJ after 250, 500 and 750 g preloads). There was a large difference between 0 and 1.26 MJ, but little difference in effect between 1.26 and 2.51 MJ preloads. Mean energy intakes in the buffet after the 0, 1.26 and 2.51 MJ preloads were 6.17, 4.83 and 4.42 MJ. These results suggest that the weight or amount of food affects subsequent appetite and food intake, but the effect of energy is stronger. (C) 1996 Academic Press Limited
