'' ... The researchers got their test subjects to drink a shake every day for a week that contained as much whey or casein as one and a half litres of milk. One group of boys drank a shake containing 11 g of whey protein, the other group drank a shake containing 42 g of casein. The researchers analyzed the boys' blood before and after the trial.
When the researchers used statistics to filter out the significant effects from the analyses, they noticed that consuming whey proteins on an empty stomach drove up insulin levels by 21 percent. Casein had no significant effect on the insulin level.''
