You're overcomplicating things. Something like spaghetti and meatballs is a P+C meal.. Or something as simple as a roast beef sandwich lol.
Protein and fats could be maybe some bacon and eggs.. Or my personal mainstay, a big bowl of ground beef, veggies, topped with some hot sauce.
Just follow along as best you can and you should be in a lot better shape. I'm sure if I counted every little thing on the label, this advice wouldn't apply lol. You're going to have fats and carbs, even in small amounts, from just about everything. Just worry about eating your protein.. Other than that, just try and have your cereal, oatmeal, breads, grains, ect in the morning/afternoon.
