Breakthrough research from Purina in 2002 proves CR works for large mammals (many species of dogs and humans are large mammals!).

In 1987, researchers led by Dennis F. Lawler at the Purina Pet Institute in St. Louis began a study of man's best friend. Lawler and his colleagues paired 48 retriever puppies by weight and gender. Between the ages of 8 weeks and 3.25 years, one of each pair was permitted to eat as much as it desired; its pair-mate was fed 75 percent that amount. From 3.25 years onward, food given to the all-you-can-eat group was limited to prevent obesity, while the low-calorie animals received 75 percent as much as the others.
Throughout the dogs' lives, the researchers monitored weight, health, and biochemical indicators of aging. The median lifespan of the diet-restricted dogs—the age by which half had died—was 13 years. That's about 22 months longer than that of their pair-mates, says Lawler. |
