Abstract: | The total food consumption of experimentally naive rats following 24, 48, 72, and 96 hr fasts was observed during the period of the recovery of body weight. The total amount of food consumed in excess of prefast food consumption was found in all groups to be equivalent to 24 hr intake and was, therefore, independent of degree of fast and body weight lost. Moreover, it was found that rats recover lost body weight following a fast even when intake is held to prefast levels. These findings suggest that the regulation of body weight may be under the control of mechanisms in addition to the control of food intake. |
