Ingestion patterns in hyperphagic and normal rats.

Abstract

The patterns of food ingestion displayed by normal, obese hyperphagic, and dynamic (nonobese) hyperphagic rats were studied using a liquid and a solid diet. The results showed: When eating a liquid diet, dynamic hyperphagics ate about twice as much as normals; obese hyperphagics ate slightly more than normals. When eating solid diets, dynamic hyperphagics ate larger meals and more frequently; obese hyperphagics ate large meals but less frequently than normals.
