简要总结
Gut hormones have therapeutic potential in the prevention and treatment obesity and type 2 diabetes (T2D). Rodent evidence suggests that calcium may potentiate the effects of protein ingestion on gut hormone secretion. Evidence in humans however, is lacking. This study aims to assess whether the addition of calcium to protein ingestion augments postprandial gut hormone availability in humans.

Whey protein hydrolysate
Whey protein hydrolysate (50 g) will be consumed by participants in the morning between 8-10 am after 8-14 h fasting. Blood samples, appetite scales and expired breath samples will be taken in a regular intervals for 2 h after ingestion.
干预措施: Whey Protein Hydrolysate (Dietary Supplement)
Whey protein hydrolysate plus milk mineral supplement
Milk mineral supplement (equating to 1000 mg calcium) plus whey protein hydrolysate (50 g) will be consumed by participants in the morning between 8-10 am after 8-14 h fasting. Blood samples, appetite scales and expired breath samples will be taken in a regular intervals for 2 h after ingestion.
