目的：研究在高碳水化合物、脂肪或蛋白质食物刺激下，食物形式对瘦人和肥胖成年人的食欲和能量摄入的独立影响。设计：采用相匹配的饮料和固体食物形式的交叉饮食挑战：高碳水化合物（西瓜和西瓜汁）；高蛋白质（奶酪和牛奶）；高脂肪（椰肉和椰奶）。受试者：体重稳定的瘦肉（18-23 kg/m(2)；N = 60）和肥胖（30-35 kg/m(2)；N = 60）成年人（18-50岁）共120名。四十名不同的参与者（N = 20 名瘦者和 20 名肥胖者）对每种食物系统进行了测试。测量：食欲、食物适口性和膳食摄入量。结果：无论主要能量来源如何，饮料食品形式引起的补偿性饮食反应比相匹配的固体食品形式更弱。因此，在摄入高碳水化合物、高脂肪和高蛋白质食物的饮料形式的日子里，每日总能量摄入量分别显着增加了 12.4%、19% 和 15%。这更多是由于对饱腹感的影响较弱。肥胖参与者在午餐时摄入了较高的能量，包括饮料中的高蛋白负荷，但瘦人和肥胖参与者之间的总体差异较小且不系统。结论：食物流变学对能量摄入具有独立影响。饮料的饮食补偿弱于营养成分相当的固体食物形式。因此，它们对促进正能量平衡构成更大的风险。
Objective: To investigate the independent effect of food form on appetite and energy intake in lean and obese adults using high carbohydrate, fat or protein food stimuli.Design: Crossover dietary challenge with matched beverage and solid food forms: high carbohydrate (watermelon and watermelon juice); high protein (cheese and milk); high fat (coconut meat and coconut milk).Subjects: A total of 120 lean (18-23 kg/m(2); N = 60) and obese (30-35 kg/m(2); N = 60) adults (18-50 years old) with stable body weight. Forty different participants (N = 20 lean and 20 obese) were tested with each of the food systems.Measurements: Appetitive sensations, food palatability and dietary intake.Results: Regardless of the predominant energy source, the beverage food form elicited a weaker compensatory dietary response than the matched solid food form. Thus, total daily energy intake was significantly higher by 12.4, 19 and 15% on days the beverage forms of the high-carbohydrate, -fat and -protein foods were ingested, respectively. This was due more to a weak effect on satiety than satiation. The obese participants had higher energy intake at the lunch, including the beverage high-protein load, but overall differences between lean and obese participants were small and not systematic.Conclusion: Food rheology exerts an independent effect on energy intake. Dietary compensation for beverages is weaker than for solid food forms of comparable nutrient content. Thus, they pose a greater risk for promoting positive energy balance.
