Okay, so I am on a cut right now, severe caloric deficit - 1700 calories a day. To try and fight any kind of muscle loss, I am eating a ton of protein - between 140 and 180g a day. This is very hard to do with whole foods while keeping calories so low. So, I have a protein shake, split into two servings, totaling 3 scoops of 6 star Whey Isolate, 20 oz of 1% milk, and one banana.
I drink the first half right after my workout (about 9:30AM), and the second half for lunch between one and two PM. Then I have a large, protein-heavy meal at about 6PM.
Anyway, I went to GNC today to get some more protein, and the guy there told me that if I took that much protein in that short a time, I would essentially piss most of it out and never absorb it. Is this "broscience," or is it true?
