Mean participant socio-demographic, bodily and systemic characteristics with standard error of the mean in brackets: Patients differed significantly in all measures, except age, before (T0) and after (T8) surgery and compared to lean participants, respectively (P < 0.05, two-sampled, two-tailed t-test). Education is described as years of education after high school. Glycaemia was measured with chemiluminescent technology (Cobas®, Roche, Switzerland). Serum insulin was measured with immunoassay technology (LiaisonXL®, Diasorin, France). Serum leptin was determined using radioimmunoassay kits (Linco Research, St. Louis, MO, USA).
