If you do nothing else in life sure you can eat till you are blue in the face. Outside of dude cussing, he did drop not one bit of info even a middle school kid doesn't know. Here is the problem, almost everything that is clean is low calorie. Let me repeat that loud and clear. Almost everything under the fucking sun that is clean is low calorie. Especially if you exclude, which may people do, red meat. So when a lot people talk diet and clean eating, truth be told on average they are only consuming about 3000 calories a day. Your diet which is mostly chicken based, you said that, you are maybe hitting 3-3.5K without any protein. 30 ounces of chicken, cooked clean without skin, is only about a 1000 calories or so a day.
Most honest people will tell you, many of the monsters, like CT Fletcher, to get large amount of calories you are going to eat fast food and stuff alike. Phelps swallowed 12000 calories day, mostly MCDs. But so many criticized supplementing, but in the next breath try to pass off that just eating 5000 clean calories or more is just a natural easy feat.
And quoting a cat about diet that has injected himself with every known fucking short cut drug under the sun, hey I expected a little better coming from you.
In wrap up, many need to define what is "clean" eating.
