Can I freeze, cook, or prepare protein in advance?
Yes. Freezing, thawing, cooking, and reheating protein do not make the protein useless. Texture may change, and overcooking can make food less enjoyable, but the protein still counts.
Food safety matters more than nutrient anxiety. Cool cooked foods promptly, store them appropriately, reheat thoroughly, and do not let meal prep sit at unsafe temperatures. A slightly less perfect but reliably prepared protein source is often what makes running diets successful during a busy week.
