How using whey hydrolysate makes athletes lose body fat
Strength athletes using whey hydrolysate lose body fat, we wrote yesterday. How exactly is that possible? The answer may be in an animal study that American researchers at the University of Missouri published in 2014. According to that study, whey hydrolysate stimulates the release of epinephrine.
The researchers divided rats into 3 groups after they had not eaten for 8 hours. One group received nothing [CTL], another group received whey concentrate [WPC] and another group received whey hydrolysate [WPH].
The researchers then analyzed the blood of the rats with metabolomics technology, which enable scientists to detect substances which they are not explicitly looking for.
After ingestion, both whey concentrate and whey hydrolysate led to a substantial increase in the amount of free fatty acids in the blood of the test animals. This suggests that the fat cells release their contents into the blood, after which the muscles and other organs can burn them. However, the increase in the fatty acid concentration was greater in the rats that had received whey hydrolysate.

You can see above how whey hydrolysate caused that increase. Thirty minutes after the rats received the pre-split protein, the concentration of epinephrine in their blood increased. Epinephrine forces fat cells to release their contents into the bloodstream.
"To our knowledge, the latter finding is novel and may be attributable to bioactive peptides acting as an adrenal catecholamine secretagogue, as other peptides [Am J Physiol. 1995 Nov;269(5 Pt 1):E903-9.] have been shown to stimulate catecholamine release", the researchers write.
