Exactly what the title says. Calculated out the costs, and at $35 for a 5lb tub of ON whey (which appears rarely on sale - it's usually more like $40 at cheapest. EAS from Costco is also $35+tax, best price), boneless skinless chicken breasts are now a cheaper source of protein.
Whey's chief advantages were that it supposedly absorbed the fastest (offset by mixing with things like milk/flax/fruit - nonexistent unless all you mix it with is water which no one does) and was significantly cheaper per gram of protein than any other source, but its price has skyrocketed in the past few years (as you all can attest, I'm sure, we pretty much saw this coming).
So should I stop buying whey and switch to boneless chicken breasts which I'll grill in advance for the week?
The mantra is that "whole foods are better," after all.
