Summarize this article:

Your eyes may be bigger than your stomach, so consider how much you would like to eat before glancing at the options. Decide how many times you will permit yourself to visit the buffet. Craft a plan and commit to it before hopping in line. Perhaps you will allow yourself to have a small starter, one healthy plate, and a small dessert, or perhaps you would like to have two moderately sized plates for dinner. When you begin to fill up your plate at a buffet, imagine that the plate is divided into four sections. This will help you visualize what a healthy meal should look like. One half of your plate should be reserved for vegetables and fruits, one quarter of the plate should contain a lean protein, and the last quadrant is reserved for whole grains. Focus on filling about half or even three-fourths of these quadrants with vegetables and fruits. Try to fill up on low-calorie, nutrient-rich vegetables and fruits to control your calorie intake while fueling your body. Scan the buffet and look for healthy, lean proteins such as fish, turkey, or chicken. Plan to limit your red meat intake, and avoid processed meats, bacon, and cold cuts. To control your portion sizes, grab a piece of protein that is similar in size to a stacked deck of cards. This should fill about one quadrant of your plate. Look for whole grains like quinoa, whole wheat pasta, or brown rice to fill up the last quadrant of your plate. Avoid processed grains like white rice, white pasta, and white bread. This should fill up the last quadrant of your plate, and should be similar to the size of a hockey puck. Looking at all the delicious food on a buffet may make you very hungry and eager to get back to the table to chow down, but be careful not to eat too quickly. Once you have satisfied your hunger, it takes about 20 minutes for your brain to pick up the signal. When you eat slowly, you are giving your brain time to catch up with your stomach to tell you that you are full. Eating slowly can help you consume fewer calories and prevent you from visiting the buffet one too many times.

Summary:
Decide how much to eat before you look at the buffet. Imagine your plate is divided in quadrants. Fill your plate with vegetables and fruits. Portion out proteins. Eat a variety of whole grains. Eat slowly to control your food intake.
