Caloric Restriction and Insulin Secretion
|ClinicalTrials.gov Identifier: NCT01447524|
Recruitment Status : Completed
First Posted : October 6, 2011
Last Update Posted : October 6, 2011
Caloric restriction in obese diabetic patients quickly improves glucose control, independently from weight loss. However, the early effects of a very-low calorie diet (VLCD) on insulin sensitivity and insulin secretion in morbidly obese patients with type 2 diabetes are still unclear.
The objective of this study was to investigate the relative contributions of insulin sensitivity and/or secretion to the improvement in glucose metabolism, after one week of caloric restriction, in severely obese diabetic patients.
For this purpose, hyperglycemic clamps were performed in 14 severely obese (BMI> 40 kg/m2) patients with type 2 diabetes in good glucose control (HbA1c <7.5%), before and after 7 days on VLCD 400 kcal/day.

Behavioral: Very Low Calorie Diet
- Change from baseline in insulin sensitivity at 7 days [ Time Frame: At baseline and after 7 days of Very Low Calorie Diet ]Insulin sensitivity was measured at baseline (hospital entry) and after a 7 day very low calorie diet.
- Change from baseline in insulin secretion at 7 days. [ Time Frame: At baseline and after 7 days of Very Low Calorie Diet ]Insulin secretion was measured at baseline (hospital entry) and after a 7 day very low calorie diet.
