Foods can be classified according their sensory differences, and physical and chemical structure. Among their physical characteristics, the consistence may play a role on satiety. The increased consumption of energy-yielding beverages, especially soft drinks, has been related to weight gain. Some studies have shown that solid foods seem to suppress appetite longer than liquids. On the other hand, others have shown the opposite. In fact, data from literature about this theme are not conclusive, likewise involved mechanisms in this area have not been clearly defined. Thus, the main aim of this study was to verify the influence of liquid and solid foods on energy intake, controlling the potentially confounding factors seen in previous studies. In this way, Electronic Appetite Rating System (EARS) was used to record participants appetite sensations in three different macronutrient load experiments (n=98), each one using a matched solid and liquid sample. Food records were used to evaluate later energy intake. Sample size was n=40 for the protein and carbohydrate experiments, and n=18 for the fat. Participants had a tendency of higher energy intake during lunch and during the day when received liquid load, compared to solid, in the three experiments. Satiation was clearly smaller for the obese participants, with the liquid load, in the protein experiment. Further more, satiety was smaller with the liquid load in the carbohydrate experiment. This study shown liquid foods have a weaker influence on appetite control, especially in a short term, compared to solid ones. Therefore, the consumption of caloric liquid foods must be limited in the prevention and treatment of obesity.
