Resveratrol-induced remodelling of myocellular lipid stores: A study in metabolically compromised humans.

ABSTRACT: In non-athletes, insulin sensitivity correlates negatively with intramyocellular lipid (IMCL) content. In athletes, however, a pattern of benign IMCL storage exists, which is characterized by lipid storage in type I muscle fibres, in small and numerous lipid droplets (LDs) preferable coated with PLIN5, without affecting insulin sensitivity. Administration of resveratrol has been promoted for its beneficial effects on glucose homeostasis. We observed that 30 days of oral resveratrol administration (150 mg/day) in metabolically compromised individuals showed a 33% increase in IMCL (placebo vs. resveratrol; 0.86 ± 0.090 AU vs. 1.14 ± 0.11 AU, p = 0.003) without impeding insulin sensitivity. Thus, the aim of the present study was to examine if a resveratrol-mediated increase in IMCL content, i
