While the classic ketogenic diet is commonly used for younger children, compliance with the ketogenic diet can be difficult for older children and adults. Pretranslational suppression of a glucose transporter protein causes insulin resistance in adipocytes from patients with non-insulin-dependent diabetes mellitus and deficlencia.

Extensive studies have been conducted to assess the role of GLUT4 in changes related to insulin sensitiveness, such as diabetes mellitus type 2 DM2.
