Rooster- I work out 6x week (Crossfit) and I always have 4 packets a day plus the 2 egg whites. Sometimes I even have 5 packets if it is a particularly tough workout. I would keep up with the 4 packets on workout days and add the egg whites, I wouldn't substitute them b/c they are not nutritionally equivalent. Also, if you read Dr. Tran's book, he says that we don't digest all of the protein from animal sources, which is why we eat the packets. This could just be his plan to make $$$, but for now I am going with it
