Evolution of glucose and C-peptide during the hyperglycaemic clamp pre- and post-intervention. Glucose during the hyperglycaemic clamps pre-intervention and 3 weeks post-intervention with (a) PSMF (n = 10), (b) RYGB (n = 10) and (c) SG (n = 10). C-peptide during the hyperglycaemic clamps pre-intervention and 3 weeks post-intervention with (d) PSMF, (e) RYGB and (f) SG. Data are presented in mean ± SD. PSMF: protein-sparing modified fast; RYGB: Roux-en-Y gastric bypass; SG: sleeve gastrectomy.
