The yolks are where the cholesterol and fat are found, egg whites have lots of protein and few carbs. It is a great low-fat protein source. I do consume quite a lot of these, with the occasional whole egg.
Other staples are skinless chicken breasts, turkey bacon, turkey sausage, broccoli, brussel sprouts, apples, bananas, peanut butter, salad greens, onions, tomatoes, carrots, and other veggies. Some brown rice and low fat granola.
