    Weight Loss Dietary Changes

    Focus on Protein

    Since your stomach capacity is severely restricted, you must make sure to have enough protein in your diet to keep healthy. At least 50 grams of protein is recommended. Foods that are high in protein include lean meats, poultry, fish, cheese, eggs, nuts, tofu and seafood.

    At each meal, concentrate on eating protein foods first so you don't fill up on other foods. Protein-rich foods are more satisfying and filling than carbohydrates, and they will help you lose more weight rapidly and healthfully. A high protein intake also will promote healing after surgery.

    Stay Hydrated

    • Drink at least six 8-ounce cups of fluid each day to avoid becoming dehydrated. Sip slowly, consuming at least 1/2 cup every hour between meals throughout the day. It is best not to use a straw because you will swallow excess air that may lead to discomfort.
    • Do not drink with meals because there is not enough room in your stomach for both food and fluids. Fluids move quickly through your stomach and can be taken up to the time you sit down to eat.
    • Wait 60 minutes after finishing a meal before drinking fluids. If you drink fluids with meals or have too much at one time, you will be uncomfortable and may vomit.
    Recommended beverages include water (the best), sugar-free drinks, tea, coffee, natural juices with no sugar added and skim milk, if you can tolerate it. Studies show that a high water intake helps promote weight loss and wound healing, and helps prevent constipation. Avoid carbonated beverages - or allow them to go flat before drinking - because the bubbles can cause severe cramping and overstretch your stomach pouch.

    Eliminate high-calorie drinks such as regular sodas, sugary fruit juices, whole milk, milkshakes and alcoholic beverages as these impair weight loss and are a common cause of weight gain.

    Adjust Eating Habits

    Avoid snacking between meals. Snacking will prevent you from losing weight even though you have had the surgery.

    People who succeed at reaching and maintaining their weight goals after bypass surgery are those who eat three small, well-balanced meals each day, and a maximum of two small, low-fat snacks.

    Tips for Success


    The best way to feel satisfied is to eat your meals very slowly. Chew each bite up to 30 times, and try to get maximum enjoyment from it.

    Eat protein foods first as they will help you to feel full sooner. Stop eating when you first notice a sensation of fullness or abdominal pressure.

    Don't worry if you have not finished the food on your plate. If you follow the dietary guidelines and take your daily vitamin supplements, you will get adequate nutrition even with a very small food intake.

    Successful habits include taking very small bites, using a small plate, eating with a baby spoon, and placing an EAT SLOWLY! sign in front of you.

    Take at least 30-45 minutes to eat and have regular mealtimes. Eat only at the table, not in front of the television or on the run. Prepare attractive meals, and learn to savor each bite, thinking about how good you will feel when you reach your target weight.

    Explain to family members and friends why you must make these changes, and ask for their support.

    Take your meals to work so you won't be tempted to eat fast food or junk food. In a restaurant, ask the waiter to bring you a half order, or to package up half the meal to take home even before it's served. Many restaurants will make special accommodations if you show them the wallet card provided as part of your surgery program.
