Mean daily food intakes (g) and body weights (g) of rats with filled balloons (7 mL), empty balloons, and no balloons over 8 weeks. In the rats with filled balloons, intakes decreased sharply in the 1st week and rose gradually, but remained lower through the 7th week (P < 0.01). Body weight remained reduced throughout compared to rats with empty balloons or rats with no balloons.
