入选标准

  • Patients aged 35-65 years;
  • BMI > 40 kg/m2;
  • BMI > 35 and <40 kg/m2 with co-morbidity, which is expected to improve after surgically-induced weight loss;
  • A history of longstanding obesity (>5 years);
  • Proven failed attempts to lose weight in a conventional way, or primarily successful weight loss with eventual weight regain;
  • Intention to adhere to a postoperative follow-up programme.

排除标准

  • BMI> 50 or body weight > 150 kg (because it is impossible to safely put people above this weight on a standard table for MRI);
  • Subjects with disease related obesity, i.e. Cushing or medication related obesity;
  • Use of medication known to affect glucose or lipid metabolism (i.e. prednisone)
  • Monogenetic diabetes: MODY, Mitochondrial diabetes;
  • LADA (adult-onset latent autoimmune diabetes); detected by c-peptide measurement on screening.
  • Impaired renal function (serum creatinine > 176 μmol/L);
  • Leg ulcers, gangrene.
  • Any genetic or psychiatric disease (e.g. fragile X syndrome, major depression) affecting the brain
  • Any significant chronic disease
  • Renal or hepatic disease
  • Pregnancy
  • Recent weight changes or attempts to loose weight (> 3 kg weight gain or loss, within the last 3 months)
  • Aerobic exercise more that 3 times 60 minutes a week
  • Alcohol consumption of more than 28 units per week at present or in the past
  • Recent blood donation (within the last 2 months)
  • Recent participation in other research projects (within the last 3 months), participation in 2 or more projects in one year
  • Contra-indications to operative procedures as regular in bariatric surgery
  • Contra-indications to MRI scanning
