So, by most research [1-4], you need unlikely more than 1.8g/kg of body mass. Slightly more if you're _cutting_ weight, and less the more well trained you are. Let's count high (2g/kg) for the sake of argument. I have no idea how big you are, but let's say you weigh 90kg. That's 180g of protein a day.

That's 667g of chicken a day, or less if you combine it with yoghurt, eggs, beans, protein powder, etc. That's ~1050kcal if going just chicken.

That's all the protein you need. If you're gaining, I'm assuming you're aiming for 2500kcal and up. 3000? 4000?

Eating any more protein than that is a waste at best, and kidney stones at worst. Just eat whatever you want on top of getting your protein quota. Carbs aren't great, but some won't hurt you. And you should really go for more fat, and that's very calorie dense.

And just to reiterate: I'm counting very high on protein, it's unlikely you'll use more than 150g a day, if that. And that will significantly decrease the amount of kcal you'll get in the pursuit of protein. Go nuts with the rest.
