Obesity is commonly correlated with metabolic complications such as insulin resistance, type 2 diabetes mellitus, dyslipidemia, arterial hypertension and metabolic syndrome that are significant risk factors for cardiovascular disease and mortality. However, some obese patients are at decreased cardiovascular risk and they are considered metabolically healthy. To date, the concept of “metabolically healthy obesity” (MHO) remains underappreciated and an accepted global definition is still lacking.
