The objective of the present study was to determine the effect of replacement of fat by sucrose polyester (SPE) within a lunch or evening meal on subsequent energy intake and appetite control. The 2 x 2 design was intended to examine the effect on appetite of reducing the total energy and fat content of a meal (lunch or dinner) by replacement of natural fat with 55 g SPE. The effects were monitored by measuring motivation to eat or actual food consumption during the remainder of the test day (day 1) and throughout the following day (day 2). The 2 x 2 design yielded four conditions which were a control meal (5192 kJ, 73.2 g fat) and a fat-replaced meal (3305 kJ, 54.6 g SPE, 24 g fat) at midday (lunch) or in the early evening (dinner). No significant differences were seen in ad lib. energy intake after the test meals on day 1 or day 2. Certain differences were detected in fat intake on day 2 but these did not suggest nutrient compensation in response to the fat replacement. Subjective assessment of motivation to eat did not indicate that the fat-reduced meal had a weaker satiating efficiency than the control meal. A reduction in fat content, using fat replacement, did not reduce the satiating efficiency of a test meal given at lunch or dinner. No energy or macronutrient compensation occurred following the reduction in energy or fat intake during the rest of the test day or during the whole of the next day.
本研究的目的是确定在午餐或晚餐中用蔗糖聚酯（SPE）替代脂肪对后续能量摄入和食欲控制的影响。2×2设计旨在通过用55克SPE替代天然脂肪来减少一餐（午餐或晚餐）的总能量和脂肪含量，从而检验对食欲的影响。通过在测试日剩余时间（第1天）和接下来一整天（第2天）测量进食动机或实际食物摄入量来监测效果。2×2设计产生了四种情况，即中午（午餐）或傍晚（晚餐）时的对照餐（5192千焦，73.2克脂肪）和脂肪替代餐（3305千焦，54.6克SPE，24克脂肪）。在第1天或第2天的测试餐后，随意能量摄入量没有显著差异。在第2天检测到脂肪摄入量有某些差异，但这些差异并不表明存在针对脂肪替代的营养补偿。对进食动机的主观评估并未表明脂肪减少餐的饱腹感效率比对照餐低。使用脂肪替代物降低脂肪含量并没有降低午餐或晚餐时测试餐的饱腹感效率。在测试日剩余时间或接下来一整天能量或脂肪摄入量减少后，没有发生能量或常量营养素补偿。
