Owen and Canto live near each other. They lead similar lives and are close in age,but they look very different. Canto is strong and healthy. Owen, on the other hand, is show and heavy. He is losing his hair, and he moves like and old man.
The biggest difference between Owen and Canto, however, is their life expectancy. Scientist expect Canto to live 30 percent longer then Owen. Why? Every day for 17 years, Canto has eaten a diet with many fewer calories than Owen. Scientist think this is the reason Canto does not have heart disease or diabetes, common health problems in old age. It seems that eating less has kept Canto's body younger.
Owen and Canto are not people - they are monkeys. They live in a scientific research laboratory at the University of Wisconsin in the United States. Scientists at the lab are studying the effects of low-calorie diets. Does eating a diet with many fewer calories in it have health benefits? Does eating less also increase life expectancy?
Will eating fewer calories lead to a greater life expectancy for humans? It will take scientists much longer to find this out. Humans live much longer then laboratory animals, such as mice and monkeys.
