Whey Protein Could Be the Cause of Your Acne
If you have eliminated sugars and dairy in your diet but are still consuming whey protein post workout, this could be the cause of your acne, especially if it is located on the trunk. It is commonly overlooked as many people don't recognize that whey is isolated from milk.
I made this mistake myself recently. As a teenager I had really bad acne so I still get some outbreaks here and there, but nothing major. These past few months I have been having whey post-workout again after having been off it for a long time, and noticed a lot of acne starting on my back and shoulders. I'm going back to EEAs post workout now to see if it is the whey causing the acne.
Looking at some studies, whey is a fairly common cause of these outbreaks so if you have been seeing an increase in the amount of acne on your trunk and can't relate it to your nutrition, whey could be the source of the problem that you may have missed.
If you are worried about a post-workout shake of some sort, then you could take something like the following mix:
Depending on your goals, you can tailor it to your needs.
