Research spanning 70 years has shown that a dietary regimen of reduced calories without malnutrition can increase life span and delay the onset of multiple age-related diseases.1-3
Purina studies show that maintaining optimal body condition can improve both life span and health span in dogs.4-5
In a 14-year study, Purina scientists were the first to prove the importance of keeping dogs in lean body condition throughout their lives.4
In this landmark study, researchers tracked the lifetime health of 48 Labrador retrievers. Researchers compared the health of lean-fed to control-fed dogs. The lean-fed dogs received 75% of the caloric intake of the control-fed dogs. The results showed that lean-fed dogs lived better, for longer.
By 2 years of age, the frequency of hip dysplasia in the lean-fed puppies was 50% less than in the control group, and was much less severe.
By the end of the study, 83% of dogs fed the control diet had developed radiographic signs of hip OA compared to 50% of the lean-fed group.
