If you cook your meat with different types of veggies and spices it can change the entire flavor of the meat, so its never boring. Fruits can also help change the flavor of the meat, try a low fat mango salsa over a chicken breast. Take tilapia flank and bake it with some tomatoes, bell pepper, a little lemon juice, a sprinkle of rosemary and thyme, it gives it an Italian flavor. There are so many combinations you could use. Red meat is okay on occasion, just don’t eat to much, there is also turkey low cal and high protein. Don’t for get about your complex carbs whole wheat and fruits. Keep a journal of how much you eat at each meal and the calories, fats, and carbs that are in them, try to stay within your limit (RMR), and you should be good to go. Good luck
