Dietary sucrose supplementation fails to modify fat deposition in lean or obese rats

The effects of sucrose supplementation on body composition and heat production were studied in lean, dietary (cafeteria diet) and genetically (Zucker fa/fa) obese adult (60 days) rats. Sucrose supplement (29 kJ) for 10 days did not result in significant changes in the pattern of energy (fat) deposition or carcass composition. There were no alterations, either, in heat production measured by direct calorimetry. Under the conditions studied, sucrose intake did not affect lipid deposition or thermogenesis.
