Obesity alters lipid and carbohydrate metabolism, which has an impact on micronutrient status. Zinc affects lipid and glucose metabolism while also acting as an anti-inflammatory and antioxidant in various physiological processes. It has a direct effect on the insulin-signaling system and acts as an insulin mimic. In this study we predicted that zinc deficiency in obese Serbian adults affects anthropometric parameters, lipid and glucose metabolic profiles, inflammation, and atherosclerotic markers. We conducted a case-control study with 31 adult obese individuals and 31 controls. Different methods were used to determine the values of anthropometric and biochemical parameters. Obese participants had significantly decreased serum zinc levels compared to controls (
