Break it into 8 meals. Macronutrient ratios will vary but basically get 50g of protein in every meal, 50-60g carbs, and moderate fat. That will amount to 400g protein, 400-480g carbs, and let's say 80g of fat. And you're right at 4100kcal easily. And those are relatively small meals. For instance 8oz. ground beef, 8oz. yam, and a side salad would be an example meal.
