Likely yes, but I've had enough chicken breast for life during my fit 20s. I just don't feel like stuffing myself with tasteless sources of protein anymore and testy ones (burgers, steaks, grilled salmon, etc.) will cause unwanted side effects and risks when consumed in high amounts.

Even bodybuilders and powerlifters admit that 2g protein per kg of body weight is about all you need. You can get that with a normal diet and a couple of protein shakes, which taste fine if you use milk and half a banana. You don't need to eat a whole chicken breast for every meal.

I made spaghetti bolognese last night and it had 60 grams of protein per 800 kcal serve. Admittedly I used lean kangaroo mince, because I'm Australian and it was on sale. Still: three meals like that and you wouldn't even need a protein shake.

I have yet to see anything against regular eating of fish and fatty fish other than the "scare" of heavy metals, which only applies for wild fish.
