dc.description.abstract | O consumo excessivo de alimentos com alto conteúdo de gordura tem sido associado com o aumento da obesidade. Os efeitos fisiológicos e metabólicos do consumo de dietas altas em gordura têm sido estudados extensamente, contudo os mecanismos comportamentais relacionados com o desenvolvimento da obesidade pelo consumo dessas dietas têm-se explorado em menor medida. Portanto, o objetivo deste estudo foi caracterizar as mudanças nos padrões comportamentais da alimentação produzidas pelo consumo de uma dieta alta em gordura durante dez dias. Utilizaram-se ratos de laboratório macho Wistar, com acesso livre ao alimento, designados a um de dois grupos, e durante dez dias estiveram sob uma dieta alta em gordura (45 % de calorias provenientes de gorduras) ou uma dieta padrão de laboratório. Nos dias 1, 5 e 10, realizou-se uma análise detalhada do comportamento alimentar ao início do período de escuridão. Os resultados mostraram que os sujeitos expostos à dieta alta em gordura acumularam mais gordura corporal e tiveram maior eficiência da alimentação do que o outro grupo, sem aumento do peso corporal nem alterações do padrão da sequência de saciedade comportamental. Isso sugere que a exposição a dietas com alto conteúdo de gordura pode produzir mudanças comportamentais antes de apresentar um ganho de peso excessivo, o que afeta principalmente os mecanismos de controle de eficiência alimentar. | |

dc.description.abstract | Excessive consumption of high-fat food has been associated with increased prevalence of obesity. The physiological and metabolic effects of high-fat diets have been extensively studied. Nevertheless, the behavioral mechanisms associated with the development of obesity induced by consumption of these diets has been less explored. Therefore, the aim of the present study was to characterize the changes in the behavioral feeding patterns produced by the consumption of a high-fat diet during 10 days. Male Wistar rats with free access to food were assigned to one of two groups, and for 10 days, they had access to a highfat diet (45 % calories from fat) or to a standard diet. Detailed analysis of feeding behavior was performed on days 1, 5 and 10 at the beginning of the dark period. The results showed that subjects exposed to the high-fat diet accumulated more body fat and showed increased feeding efficiency, in absence of excessive body weight increase or alterations in the behavioral satiety sequence pattern. These findings suggest that exposure to high-fat diets may produce behavioral changes before excessive gain of body weight occurs, primarily affecting control mechanisms of feeding efficiency. | |
