Tons of variables here! Hard to answer, and mileage varies. I'd personally up my carb intake to 1//3 of my caloric load, so my ratio was 33/33/33, fat/protein/meat. But I haven't trained very hard, so I can't be sure that's correct! I typically stay low-carb for days on end and then go higher-carb for a few days - but I don't normally push it physically every single day. Tried to, but turns out my schedule is too weird for it.
Definitely high-protein, and some fat. But you're going to need those starchy carbs (I say) for daily heavy work-outs.
Focus especially on nutrient-dense food. Lots of liver (don't overdose) and eggs, leafy greens and maybe more nuts than you'd eat if sedentary. And sweet potatoes, bananas, apples, etc.
I'd emphasize rest, but it sounds like you won't be getting any.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
