Whey Protein Dose-response Effect on Daily Glycaemic Excursions in Very Old Individuals With Type 2 Diabetes
The goal of this placebo-controlled, partial crossover design study is to identify the impact of consuming whey protein before meals on free-living glucose control in older adults living with type 2 diabetes.
The primary specific objective is to determine the effect of a thrice daily whey protein pre-meal supplementation at two doses, on glucose excursions over a 7-day free-living period in adults aged 70-90 years of age, living with type 2 diabetes, compared with a non-protein placebo.
Participants will consume the whey protein and placebo for 7 days each, before each meal. All participants will consume the placebo and one of two doses of whey protein, in a randomised order.
