ABSTRACT The objective of the present study was to evaluate the effects of coffee intake with and withoutcaffeine on feeding behavior in rats. Sixteen rats was exposed to 2g, 3g, 4g and 5g of coffee withcaffeine and without caffeine diluted in 200ml of water. Subjects were assigned to 4 groups conformedby 2 females and 2 males each one. Groups 1 and 2 were exposed to coffee with caffeineand groups 3 and 4 to coffee without caffeine. Exposed to coffee for groups 1 and 3 was of ascendingform (2 g, 3 g, 4 g, and 5 g) and for groups 2 and 4 of descendent form (5 g, 4 g, 3 g and2 g). The experiment was divided in 9 phases. Phases 1, 3, 5, 7 and 9 lasted of 10 days, in eachone were provided 200ml of water and 50g food. Phases 2, 4, 6 and 8 lasted of 5 days; in eachone provided the concentrations of coffee and 50g food. The results showed that the low concentrationsof coffee registered a greater consumption in comparison with the high concentrations inboth conditions (ascending and descendent). On the other hand, coffee without caffeine was moreconsumed than coffee with caffeine.
