High-Protein Diet Prevents Glucocorticoid-Induced Fat Mass Accumulation and Hyperglycemia.

ABSTRACT: Glucocorticoid-induced diabetes is the most common form of drug-induced hyperglycemia. In addition, chronic exposure to glucocorticoids promotes lean mass loss and fat mass accumulation. In this study, we hypothesized that a high-protein diet (60% kcal; HPD) would help to offset sarcopenia during oral administration of corticosterone to C57BL/6J mice. Carbohydrates were reduced in the HPD to ensure it was isocaloric with the normal-protein diet (20% kcal; NPD). We found that the HPD prevented fat mass accumulation but did not protect against reductions in lean mass in both male and female mice. Mice consuming a HPD did not develop hyperglycemia, while mice given the NPD developed hyperglycemia within two weeks. The HPD diet did not improve insulin sensitivity in response to glucocorticoids
