The purpose of your surgery is to reduce the amount of food you eat. After surgery you will be required to make several dietary changes. Bariatric surgery does not guarantee weight loss. It is best to think of bariatric surgery as a tool that you can use to help you lose weight. To achieve optimal weight loss, you will be required to do your part. The following dietary guidelines will be necessary for a successful weight loss journey.
- Eat three meals per day. Avoid snacking between meals. Snacking can prevent weight loss or promote weight gain due to excess intake of calories.
- Chew foods slowly and thoroughly. You should take at least 20 minutes to finish a meal. Put your fork down between bites and practice chewing each bite approximately 27 times. Your food should be a paste consistency before you swallow. Cut food into small bites. Foods that are tough or chewy may not be tolerated.
- Eat small amounts. Your new stomach will not be able to hold much food. Stop when you feel full and do not overfill your pouch.
- Eat protein rich foods first. After surgery, your body will need adequate protein to help build, repair, and maintain muscle tissue and organs. Protein deficiency can occur over an extended period of time which can cause fatigue, hair loss, and muscle wasting. You should always eat high protein foods first such as lean meats, tofu, beans, and low fat dairy products. You will also be encouraged to supplement with protein shakes or supplements to ensure that you are meeting your individual protein needs.
- Avoid foods that are high in sugar and fat. To be successful with your weight loss and to prevent weight gain, you must follow a balanced diet. Foods that are high in sugar and fat are considered "empty calories" and do not provide any vitamins or nutrients.
- Do not drink liquids with meals. Stop drinking fluids 30 minutes prior to your mealtime, do not drink while you eat, and wait 30 minutes after your meal is finished to resume fluid intake. This will:
- Prevent overfilling the stomach
- Keep food from flushing through your stomach too quickly
- Keep you feeling full longer
- Sip fluids slowly. Do not gulp fluids after surgery. This may cause nausea or vomiting.
- Drink 64 ounces of non-carbonated, sugar-free fluids daily. Avoid sodas, sweet teas, high calorie and high sugar juices, and alcohol. Plain water is ideal for hydration.
- Limit caffeine. Caffeine may stimulate your appetite and may irritate your new stomach.
