Influence of diet form on the hyperphagia-promoting effect of polysaccharide in rats.
Adult female rats were fed chow only, or chow plus the polysaccharide Polycose presented as a solution (32% w/v), as a powder, or as a powder mixed into the chow diet. The rats fed the Polycose solution overate and gained three times as much weight as did the control rats in the 30-day test period. The rats fed the Polycose powder or mixed diet, on the other hand, did not differ from controls in food intake or weight gain. The solution-fed rats consumed more Polycose than did the powder-fed rats, but the two groups were equivalent in their chow intake. The absolute and percent body fat of the solution-fed rats exceeded that of control rats, as well as that of powder and mixed-diet animals. The percent body fat of the powder and mixed-diet groups exceeded that of the control animals. The findings demonstrate that the form of diet presentation has a major impact on the rat's feeding and body weight responses to polysaccharide diets.
