A recent study indicates that visceral fat increases the risk of cardiovascular and metabolic diseases, even in people who appear lean [1].
This finding challenges traditional views of health based on weight, as it suggests that internal fat distribution is a more critical health indicator than overall body mass. Because visceral fat is not always visible on a scale, individuals may be unaware of their risk levels [2].
Visceral fat accumulates within the abdominal cavity, specifically between vital organs such as the liver and the heart [2]. Unlike subcutaneous fat, which sits just under the skin, visceral fat functions as metabolically active tissue [2]. This activity can directly impair the function of internal organs and trigger systemic health issues [2].
Researchers said that the accumulation of this specific fat type is more dangerous for the organism than the excess of weight typically associated with subcutaneous fat [1]. The study, highlighted on June 28, 2026, emphasizes that the location of fat stores is as significant as the total amount of fat present in the body [1].
Medical experts said that this internal fat disrupts the metabolic environment of the surrounding organs [2]. This disruption contributes to the development of chronic conditions that affect the heart and metabolic systems [1]. Consequently, a person with a healthy body mass index may still face significant health threats if they possess high levels of visceral adiposity [1].
“Visceral fat is more dangerous than subcutaneous fat.”
This research shifts the clinical focus from total body weight to fat distribution. It suggests that 'lean' phenotypes can still harbor metabolic risks, meaning that traditional weight-based screening may overlook a significant population at risk for heart disease and metabolic failure.
