Hill's Innovates Weight Loss Nutrition June 25, 2008

Reformulated Hill’s® Prescription Diet® r/d® Canine Dry Formula is Even Better

TOPEKA, Kan.,– Nearly 35 percent of American household pets are obese or overweight. Regrettably, few pet owners recognize the severity of this condition and that it can lead to diabetes, arthritis and a variety of other debilitating diseases. Already offering clinically proven results as a quality weight management option for canine patients, Hill’s® Prescription Diet® r/d® Canine pet food is now reformulated to provide even greater benefits.
The results are in. Prescription Diet r/d Canine dry is clinically proven to reduce body fat by up to 22 percent in two months and to reduce triglycerides, cholesterol and alkaline phosphatase to help promote better overall health. This weight loss pet food contains the highest level of lysine (5.8 g/Mcal) and the highest L-carnitine* level to help convert fat into energy and build lean muscle mass plus increased fiber for more effective hunger control.
“What appears to be a happy, big-boned or fluffy pet could actually be at risk for a shorter lifespan if a nutrition and exercise plan isn’t recommended and followed by the pet owner,” said Janet Donlin, D.V.M., Chief of Veterinary Business Channel at Hill’s. “We are excited about the reformulation of Prescription Diet r/d Canine because it provides veterinary health care teams with clinically proven technology that can help give their overweight canine patients a better quality of life.”
For years, veterinary health care teams have relied on Prescription Diet r/d Canine brand pet food to provide safe and effective weight loss for their overweight and obese patients. For years, Hill’s has remained constant in its belief of continual product improvement based on the latest technological advances. In addition to clinical innovations in weight loss, Hill’s has utilized the field of nutrigenomics and metabolism to provide support for the technology principles behind enhanced Prescription Diet Canine r/d. Genetic biomarkers now substantiate that reformulated Prescription Diet Canine r/d is better than ever for helping overweight and obese canine patients lose weight.
In one recent study1, gene expression profiles for obese dogs were taken to record differences from leaner dogs. A total of 30 overweight dogs with greater than 31 percent body fat (of total weight) were selected to participate in the study. The study compared rate of weight loss, lean and fat body composition changes, stool quality and blood chemistry changes.
The study found that increasing the lysine/calorie ratio rather than total protein helped the dogs in the study maintain lean muscle mass without the potential negative effects of excess protein on kidney health. The dogs eating enhanced r/d lost up to 22 percent body fat in two months and experienced positive changes in their metabolism as measured by genetic biomarkers.
