Sustained effects of a protein 'preload' on glycaemia and gastric emptying over 4 weeks in patients with type 2 diabetes: A randomized clinical trial

- A total of 25 g whey preloads slow gastric emptying and reduce postprandial glycaemia.
- This effect persists after 4 weeks of regular exposure in type 2 diabetes.
- This dietary strategy should be evaluated in larger clinical trials.

We have shown that the capacity of 25 g whey preloads to slow gastric emptying and reduce postprandial glycaemia persists after 4 weeks regular exposure in patients with diet-controlled type 2 diabetes. This dietary strategy therefore appears feasible for larger clinical trials to evaluate beneficial effects on long-term glycaemic control.Registered with the Australian New Zealand Clinical Trials Registry: ACTRN12614000831684.
