Abstract |
Aim |
The role of caloric restriction in the improvement of renal function following bariatric surgery is still unclear; with some evidence showing that calorie restriction can reduce proteinuria. However, data on the impact of caloric restriction on renal function are still lacking.
Methods |
Renal function, as measured by glomerular filtration rate (GFR), was evaluated in 14 patients with type 2 diabetes mellitus, morbid obesity and stage 2 chronic kidney disease before and after a 7-day very low-calory diet (VLCD).
Results |
After the VLCD, both GFR and overall glucose disposal (M value) significantly increased from 72.6±3.8mL/min/1.73m−2 BSA to 86.9±6.1mL/min/1.73m−2 BSA (P=0.026) and from 979±107μmol/min1/m2 BSA to 1205±94μmol/min1/m2 BSA (P=0.008), respectively. A significant correlation was observed between the increase in GFR and the rise in M value (r=0.625, P=0.017).
Conclusion |
Our observation of improved renal function following acute caloric restriction before weight loss became relevant suggesting that calory restriction per se is able to affect renal function.
