The main objective of our study is to investigate the metabolic effects of whey protein (whey protein isolate, WPI, (Lacprodan® ISO.Water. from Arla Foods Ingredients) compared to placebo when consumed by women in risk of gestational diabetes mellitus (GMD) 30 minutes prior to an oral glucose tolerance test (OGTT). We will also investigate any changes in substrate metabolism and energy expenditure using indirect calorimetry. Differences in hunger and satiety parameters as well as rate of gastric emptying will also be assessed. Furthermore, we will investigate the glucose response when the women consume the intervention at home in their own environment 30 minutes before breakfast in various doses (placebo, 10, 15, 20, 30 g whey). The women will be monitored with continuous glucose monitors, activity monitors and all meals will be provided. The two study days in the laboratory will be repeated 3-9 months after pregnancy. The purpose of this is to be able to compare the metabolic response of pre-meal whey during pregnancy with the response in a not-pregnant state. The study days at home will not be repeated after pregnancy.
