The main objective of our study is to investigate the metabolic effects of a i) ordinary whey protein (WHE) and ii) a specific whey protein fraction (speWHE) when the interventions are ingested by patients with type 2 diabetes 30 minutes prior to an oral glucose tolerance test (OGTT). We will also investigate the glucose response when the patients ingest the interventions at home in their own environment 30 minutes before breakfast and dinner (2days) and also monitor glucose levels without interventions (2 days).
