John Flanagan, PhD, from Royal Canin, discussed findings from a recent study at the 2026 Western Veterinary Conference regarding a specialized diet for overweight diabetic cats. The study explored the effects of Glycoadvanced, a high-protein, low-digestible carbohydrate diet aimed at promoting weight loss and improving diabetic remission rates in these animals.

The research involved 72 overweight diabetic cats previously reliant on insulin. Participants were divided into two groups: one received Glycoadvanced to maintain their weight while the other followed a caloric restriction plan to facilitate weight loss. The study aimed to determine whether transitioning these cats to the new diet could support more favorable health outcomes, specifically diabetic remission.

Flanagan outlined a new diabetes classification system developed from a meeting of specialists in internal medicine and nutrition. This system recognizes that a cat’s needs can vary based on their diabetes status, body condition, and treatment, thus facilitating more personalized care.

For overweight diabetic cats, the study recommended gradual weight loss between 0.5% to 2% per week, ensuring safety throughout the program. This was critical as such interventions had not been extensively documented in veterinary medicine. The research team implemented numerous safety measures, which included monitoring clinical chemistry and hematological parameters closely, reporting only minor issues such as nonclinical hypoglycemia.

The study found that Glycoadvanced addressed specific dietary needs for diabetic cats, including low digestible carbohydrates and high protein content, while managing calorie intake to support weight loss. Most cats maintained normal renal and liver function, though one cat in the control group showed a slight deterioration in chronic kidney disease.

High engagement from pet owners contributed to the study's success. They were provided with tools for tracking food portions and monitoring their cats' weights and blood glucose levels, ensuring higher compliance with the dietary regimen.
