- Primary Outcome Measures
Name Time Method - To assess and compare the net incremental area under the curve of satiety-related plasma amino acids and derivatives in response to lactase-containing milk supplemented with either casein or whey protein in a randomized controlled cross over study in subjects 12-18 months after primary gastric bypass surgery.
- Secondary Outcome Measures
Name Time Method - To assess and compare the effect of the ingestion of both protein supplements in lactase-containing milk on plasma concentrations of all amino acids and derivatives, plasma concentrations of anorexigenic gastrointestinal hormones PYY and GLP-1, satiety, hunger, dumping symptoms, heart rate, blood pressure, glucose metabolism and ad libitum food intake after completion of the test meal in a randomized controlled cross over study in subjects 12-18 months after primary gastric bypass surgery.<br><br>- To assess the self-reported dietary patterns, macronutrient consumption, energy intake, eating behaviour and physical activity measured by questionnaires in subjects 12-18 months after primary gastric bypass surgery.
