Rat body size and tissue composition changes from pre-weaning to three months age resulted from voluntary hyperphagia triggered by offering a cafeteria diet. The effects of a 24 hour starvation period in both cafeteria and chow fed controls were compared. Obesity develops earlier in females than in males. This difference is related to the growth patterns in both sexes. Obesity occurs at the stages of development when growth rate decreases. Cafeteria fed female rats attained a 32% greater weight than their controls, with lumbar adipose cords that were 4 times heavier and brown interscapular adipose tissue 2 times heavier than controls. The overall cafeteria fed versus chow fed rat differences in the effects of a 24 hour starvation, were minor but less liver glycogen and much more skeletal muscle lipids were mobilized in the cafeteria fed rats than in controls.
