Abstract

Although obesity is an important risk factor for type 2 diabetes and cardiovascular diseases (CVD), the association of obesity with cardiometabolic disorders and mortality varies widely among obese individuals. Recently, unique subsets of individuals have been getting novel attention; metabolically obese but normal weight (MONW) and metabolically healthy obese (MHO) people. The MONW individuals, despite having a normal body mass index (BMI), display several risky phenotypes including reduced insulin sensitivity, high blood pressure (BP) andatherogenic lipid profiles which contribute to the increased risk of CVD. On the contrary, individuals with the MHO phenotype exhibit normal insulin sensitivity, healthy BP levels, and favorable glycemic and lipid profiles despite having high BMI. Identification of MONW and MHO individuals may facilitate more accurate risk stratification and effective intervention strategies for the prevention of CVD. This manuscript will summarize the pathogenesis and clinical implication of these various body size phenotypes.
