Make sure that you not only eat three meals daily but that fruits and vegetables are at all meals. You should be consuming at least 4.5 cups of produce daily. Take advantage of the salad bar, cooked veggies, and fresh fruit.
When you eat grains, try to choose whole grains such as brown rice, whole wheat bread, and whole grains cereals. You should be consuming three servings of dairy such as nonfat or low fat milk, yogurt, and cheese daily.
Finally, choose leaner cuts of meats such as roast beef, and skinless poultry such as boneless chicken breast more often than fried and fatty cuts of protein.
