Preventing Renal Functional Abnormalities With Calorie Restriction in Subjects With Abdominal Obesity and Type 2 Diabetes at Increased Renal and Cardiovascular Risk

The study investigates whether a caloric restricted dietary regime can prevent onset and/or progression of chronic kidney disease in type 2 diabetic patients with abdominal obesity, through the amelioration of concomitant metabolic abnormalities such as insulin resistance, dyslipidemia, hypertension and inflammation, possible risk factors for the onset of kidney disease. The main aim of the study is therefore to evaluate the renoprotective effect of caloric restriction (CR) on subjects at risk of nephropathy. Secondary aim is to better understand how dietary implementation can modulate renal disease and its associated metabolic abnormalities.
