"They don't think it be like it is, but it do." -- O. C. Gamble

The main effect of diet-induced obesity in animals fed a high-fat diet is weight gain. In particular, body composition shifts towards more Fat cells. These effects persist even after the diet becomes lower in fat[1]. Accompanying the changes in body composition are changes in hormone balance. High levels of Leptin and Insulin are produced; at the same time, the body becomes resistant to both. [2]
