Abdominal obesity is associated with insulin resistance and reduced glycogen synthase activity in skeletal muscle

Insulin resistance is commonly associated with obesity. The present study was performed to investigate the relative importance of total fat mass versus localization of adipose tissue in insulin-stimulated glucose disposal (Rd) and skeletal muscle glycogen synthase (GS) activity in obese individuals. Twenty obese women with an average body mass index (BMI) of 37.8 +/- 1.3 kg/m2 and a waist to hip ratio (WHR) ranging from 0.78 to 1.02 were...
