FIG. 1.
Alterations in systemic insulin sensitivity in GBP subjects. Hepatic insulin sensitivity index, calculated as the reciprocal of the product of basal glucose production and insulin concentration (A); insulin-stimulated glucose disposal, an index of skeletal muscle insulin sensitivity assessed as the relative increase in glucose uptake during insulin infusion (B); and insulin-mediated suppression of palmitate Ra into plasma, an index of adipose tissue insulin sensitivity assessed as the relative decrease in palmitate Ra during insulin infusion (C), in obese subjects before (▪) and 1 year after (□) GBP surgery. *Value significantly different from the before GBP value; *P < 0.01, **P < 0.001.
