The article in this issue of Diabetes by Dutia et al. (1) shows that in obese diabetic patients returning to normal glucose tolerance (NGT) after gastric bypass β-cell function appears to recover if evaluated through oral glucose tolerance test (OGTT), but not if evaluated through isoglycemic glucose clamp. In fact, the plot indicating Δinsulin/Δglucose (insulin release [IR]) versus 1/homeostasis model assessment of insulin resistance (HOMA-IR) (insulin sensitivity [IS]) grows during OGTT, but stays flat or moves right, indicating …
