implicating mTORC1 activation as a possible mechanism for impaired insulin action in response to elevated lipid availability. When nutrients are available, mTOR is activated and drives anabolism as well as energy storage and consumption. mTORC1 activation contributes to obesity by mediating excess fat deposition in white adipose tissue (WAT), liver, and muscle through the transcription factor sterol regulatory element binding protein 1c (SREBP1c)
