瘦人也会得“脂肪肝”，而且死亡风险更高

Core Viewpoint - The article emphasizes that non-obese individuals are also at risk for fatty liver disease, which can lead to more severe liver damage compared to obese patients [3][4]. Group 1: Research Findings - A study involving nearly 190,000 metabolic-related fatty liver patients found that normal-weight individuals with fatty liver have a 1.14 times higher risk of liver-related events and a 1.31 times higher risk of death from liver disease compared to obese patients [4]. - The study defined normal weight as a BMI of less than 23 kg/m² for the Chinese population and less than 25 kg/m² for the UK population, with approximately 2.7% of fatty liver patients being of normal weight [4]. Group 2: Risk Factors for Normal-Weight Fatty Liver - Factors contributing to fatty liver in normal-weight individuals include poor lifestyle choices, excessive intake of fats and sugars, sedentary behavior, and chronic stress [5]. - Genetic predisposition and age-related mitochondrial dysfunction can also lead to insulin resistance, a key factor in the development of fatty liver [5]. Group 3: Management and Prevention - Recommendations for managing fatty liver in normal-weight individuals include lifestyle interventions aimed at achieving a weight loss of 3% to 5% [6]. - A balanced diet rich in quality proteins, vitamins, and regular aerobic exercise is advised to help reduce the risk of fatty liver [6][8]. - Regular health check-ups are essential for early detection of fatty liver, as it often presents no symptoms in the early stages [8].
