Protein is essential for weight loss because it keeps you full, supports muscle building, and boosts your metabolism. Aim for about 0.7–1 gram of protein per pound of your goal weight. Great sources include chicken, fish, eggs, Greek yogurt, beans, lentils, and nuts. Add protein to every meal—like eggs at breakfast, chicken or tofu in salads, and snacks like yogurt or nuts. It’s a simple way to stay satisfied and support your goals!
