Study information
Scientific title
Effect of change in pancreas and liver fat content upon beta cell function and hepatic insulin action during weight loss in type 2 diabetes: a non-randomised interventional treatment trial
Acronym
DRN 328 Pancreatic Fat Study
Study hypothesis
The aim of this study is to determine the metabolic effects of decreasing excess fat in the liver and pancreas in patients with type 2 diabetes. During an 8-week hypocaloric diet, the study will define the time course of change in response to glucose-induced insulin secretion in relation to change in pancreatic fat content and will define the time course of change in liver insulin sensitivity in relation to change in liver fat content.

Condition
Topic: Diabetes Research Network, Primary Care Research Network for England; Subtopic: Both, Not Assigned; Disease: Diabetic Control, Metabolic, Obesity
Intervention
The study involves an 8-week period of very low calorie diet (800 cal per day) using liquid based-formula diet (Optifast®) to induce weight loss. In addition to the three sachets of Optifast® per day, participants are asked to eat 240 g of non-starchy vegetables per day and drink at least 2 litres of water or calorie-free beverages per day. During the intervention period, participants are monitored on weekly to fornightly basis by members of the research team which includes a specialist dietician.
