Effect of weight loss on inflammatory biomarkers in obese dogs.

The objective of this study was to evaluate the effects of weight loss on selected serum inflammatory biomarkers in obese dogs. An experimentally induced bodyweight reduction of approximately 2.5%/week was accompanied by significant decreases in metabolic markers of obesity (lipidic profile, fructosamine, and insulin-like growth factor-1). The concentrations of acute phase proteins and of selected cytokines remained within reference ranges in obese dogs during weight loss, suggesting that significant inflammation was not a major component of this experimental model. However, adiponectin concentrations increased following the period of weight loss suggesting reduced susceptibility of these animals to obesity-related inflammation.
