Just make combinations from carb protein & fat source that suit your lifestyle, financial standings, etc. Of course there's also foods that have all 3 macros or similar. My usual carb source for breakfast is oats (+milk+water+3/4apple) (I know there's also a protein source - the milk, and the oats has all 3 macros), and I have a protein+fat source - tuna or 3 whole eggs. You get the idea, oats would be like the ideal breakfast, 80 grams oats is like 54g carbs, 6g fat, 14g protein, so you need 22g more protein and 5g fat, the fat could come from nuts and then have a protein source like chicken if you feel like it, or just have 1 egg for 6g protein and 5g fat and add milk to the oats, it will be pretty close to the macro goal. Whatever, you get what I mean, it doesn't have to be all the carbs from oats, you could do 50 grams oats and 1 apple, or whatever suits your breakfast. Same thing goes for all the meals.
