Fat-specific satiety in humans for fat high in linoleic acid vs fat high in oleic acid

To investigate the effect of 2 week use of oils high in linoleic (LA), gamma-linolenic (GLA) and oleic acid (OA) on energy intake (EI), macronutrient composition, parameters of appetite and taste perception. A randomized placebo-controlled 2-week treatment, followed by a test day. Two-week treatments, daily life; test day, laboratory restaurant. Eight overweight men and eight overweight women (body mass index 27.4+/-1.5 kg/m(2)). Three 2 week treatments, in which subjects replaced their habitual fat products by three different oils (relatively) high in LA (66.8%), GLA (20.2%) or OA (79.6%, placebo). The wash-out periods were 2 weeks. Before each intervention period, taste perception and sensory specific satiety was tested. Even though energy intake was higher during dinner, subjects ate relatively less fat with LA (45.0+/-9.4 E%, P
