Replace chicken with steak? In my experience, it's not necessarily the perceived healthiness of foods (chicken == healthy, steak == unhealthy), it's the carbohydrate amounts.

When I was in my 20's, I was relatively "hard core" about lifting weights and training. I weighed every meal, brought my own meals to cookouts, estimated macros as best I could. I was pretty obsessed with it all. As a result, I tried every diet out there, multiple times.

What I keep coming back to is low carb. By that I mean: Tons of broccoli, lettuce, cauliflower, zucchini, nuts (almonds and pecans primarily), fish, and beef. Plus, hard cheeses like Parmesan and Romano.

It's not hard to make these meals delicous. And, interestingly enough, I get "run down and depressed" when I don't eat this way. It's weird to admit that I crave vegetables like I would a piece of pizza. But, if we go out of town for a few days, and eat out a lot, I completely do.
