The concept you guys are talking about really isn't unheard of or bizarre...the idea of "if it fits your macros" is popular on a lot of nutrition forums. In the long-term I think it tends to be a bit of a crutch because the **** in most processed foods/fast foods (**** that doesn't even have caloric impact, mind you) honestly cannot be good for you (McDonalds just released that announcement that "pink slime" is officially no longer in their products).
When I'm cutting, I keep my diet very "clean" in the sense that all of my food sources are meticulously documented, weighed, and usually prepared by me, because I want to be in control of every calorie that goes into my body.
Buuutttt whenever I'm bulking, I definitely follow the "if it fits your macros" type of diet. I haven't eaten fast food in probably 5 years, everything I eat is bought from a grocery store, but not everything is considered "great" for you. For instance, when I'm bulking my main focus is on large amounts of carbohydrates because I usually gain best off of those. What are my favorite sources? Kids breakfast cereal (Cinnamon Toast Crunch and Reese's Puffs are favorites) and low-fat ice cream (Edy's Slow-Churned Variety...mouthgasm)
