Supersized portions. An average fast food meal can run to 1000 calories or more, so choose a smaller portion size, order a side salad instead of fries, and don't supersize anything. At a typical restaurant, a single serving provides enough for two meals. Take half home or divide the portion with a dining partner.

Salt. Fast food restaurant food tends to be very high in sodium, a major contributor to high blood pressure. Don’t add insult to injury by adding more salt.

Bacon. It’s always tempting to add bacon to sandwiches and salads for extra flavor, but bacon has very few nutrients and is high in fat and calories. Instead, try ordering extra pickles, onions, lettuce, tomatoes or mustard to add flavor without the fat.

Buffets – even seemingly healthy ones like salad bars. You'll likely overeat to get your money's worth. If you do choose buffet dining, opt for fresh fruits, salads with olive oil & vinegar or low-fat dressings, broiled entrees and steamed vegetables. Resist the temptation to go for seconds, or wait at least 20 minutes after eating to make sure you're really still hungry before going back for more.
