Entropy generation behaviour of the rats is affected by their diet and nature of being lean or obese. Thermodynamic analyses showed that the obese Zucker rats may generate 22,092 kJ/K of life span entropy when fed soybean oil diet and 38,718 kJ/K of entropy when fed with butter fat. Their lean counterparts may generate 15,314 kJ/K of life span entropy when fed with soybean oil diet and 47,657 kJ/K of entropy and when fed with butter fat diet. The lean Zucker rats fed with butter fat diet had 92%, while the obese Zucker rats fed with soybean oil diet had 72%, wasted life-time work potential. Obese Zucker rats fed with butter fat diet performed approximately 48% more total physical work and generated 48% more muscular heat through their life span than the lean rats fed with soybean oil diet.
