The effect of physical activity level and exercise training on the association between plasma branched-chain amino acids and intrahepatic lipid content in participants with obesity

F. Vanweert, S. C. Boone, et al.

This study reveals a fascinating link between plasma branched-chain amino acids and intrahepatic lipid content, regardless of physical activity levels. Conducted by a team of researchers including Froukje Vanweert and Sebastiaan C. Boone, the findings suggest that the reduction of intrahepatic lipids through exercise training is likely not dependent on changes in plasma branched-chain amino acids, particularly in individuals with type 2 diabetes and nonalcoholic fatty liver.

Abstract
This study aimed to evaluate the association between plasma branched-chain amino acids (BCAA) and intrahepatic lipid (IHL) content, considering the influence of physical activity level and exercise training. A cross-sectional analysis of 1983 individuals showed a positive association between plasma BCAA levels and IHL, irrespective of physical activity. A 12-week exercise intervention in individuals with type 2 diabetes (T2DM), nonalcoholic fatty liver (NAFL), and controls demonstrated that exercise reduced IHL in NAFL and controls without altering plasma BCAA levels. Therefore, exercise training-induced IHL reduction is likely independent of changes in plasma BCAA levels.
