The 24-hr. intake of saccharin and sucrose solutions was higher when rats were maintained at reduced body weights than when food was freely available. Intake of both kinds of solution during 3-hr. tests, as a proportion of 24-hr. intake, increased with concentration. Water consumption outside of tests reflected solution consumption during tests. These results suggest that the increased intake of sucrose solutions during deprivation is at least partially dependent on palatability.
