In this episode of The Pet Food Science Podcast Show, Dr. Aulus Carciofi, full professor at São Paulo State University in Brazil, discusses how obesity alters energy metabolism in dogs and cats and why traditional diet formulation approaches fall short during weight loss. He explains why nutrient requirements must be calculated in grams per body weight rather than dry matter percentages. Dr. Carciofi also highlights the role of amino acids, lean mass preservation, and metabolic adaptation during energy restriction. Learn practical, science-based insights for improving weight loss diet formulation in pets. Listen now on all major platforms!

“Formulating diets based on dry matter percentages can create the false impression of adequacy, while actual nutrient intake remains insufficient during energy restriction.”

Meet the guest: Dr. Aulus Carciofi is a full professor at São Paulo State University in Brazil, where he leads clinical nutrition research focused on pet food formulation, metabolism, and nutrition-related diseases in dogs and cats. His work emphasizes ingredient evaluation, digestibility, amino acid balance, and clinical testing of diets during weight loss.
