    How to Avoid Weight Gain Over Holidays
    Do you love the holidays, but hate the pounds that follow? You are not alone. Holidays are times for feasting and celebrating. Many people are worried about their weight. ______1______ Whether you are celebrating at the office party or sitting down for the traditional family dinner, regard eating as a time for tasting a variety of foods. The idea is to enjoy the holidays but not to eat too much. You don’t have to turn away from the foods that you enjoy.
    Here are some tips for preventing weight gain and maintaining physical fitness:
    Don’t skip meals.
    Before you leave home, have a small, low-fat meal or snack. ______2______
    Control portions.
    Use a small plate (about 10 inches) and put aside the large ones that may encourage you to “load up.” ______3______ Once you have your “tasting” serving, move away from the dining table. Doing so will make it less tempting (吸引人的) to be eating constantly as your appetite is inspired by the sight of food.
    Begin with soup and fruit or vegetables.
    Fill up beforehand with water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you feel full.
    Stick to physical activity.
    ______4______ A 20-minute walk after a meal can help burn off additional calories.
    ______5______
    Dishes that look oily or creamy may have a large amount of fat. Choose lean meats. Fill your plate with salad and green vegetables. Use lemon juice instead of dressing or butter.
    A.This may help to avoid getting too excited before delicious food.
    B.You had better turn your attention away from delicious foods.
    C.With proper planning, though, it is possible to keep normal weight during the holidays.
    D.You should be most comfortable eating an amount of food about the size of your fist.
    E. Avoid high-fat foods.
    F. Don’t let exercise take a break during the holidays.
    G. You’d better remember the Dos and Don’ts for keeping fit and slim.
