Effect of Hypocaloric Stress on Body and Tissue Composition of Rats K

Abstract

Rats fed ad libitum, a ration comprising fresh foods (F ration) for 10 days, were switched over to another ration consisting of processed foods (P ration) for a similar period. Thereafter, the animals were subjected to a 50 per cent diet restriction for a period of 10 days and rehabilitated either on F ration or P ration for an equal period. The results showed a decline in growth rate, food consumption and food efficiency ratio in the group fed ad libitum on P ration compared to that on F ration. Fifty per cent diet, restriction induced loss of body weight due to depletion of body fat. A fall in the gross weight of liver,kidney and epididymal fat pad along with a reduction in the contentsof lipid in liver and fat pad were also observed. Refeeding ofdiet-restricted rats induced hyperphagia and super-normal weight gainwith both rations. The data on liver triglycerides appeared to show anage-related rise which could be controlled by diet restriction to someextent. Feeding of P ration tended to predisperse to higher adiposetissue cholesterol attributable to higher fat content of this ration
