Gastric Sleeve Forbidden Foods
Also known as vertical sleeve gastrectomy, Weight Loss Surgery is a surgical procedure that reduces the size of the stomach by 85%. During the surgery for weight loss, a section of the stomach is removed leaving a thin tube-shaped stomach. Because the stomach is so much smaller, the patient will feel full faster and consume less food leading to weight loss.Before surgery for weight loss, patients must prepare their body for the procedure. At least two weeks before gastric sleeve, food restrictions are made. This diet prepares the digestive tract and the liver for the procedure. This pre-surgery diet also helps prepare the body for the lifestyle changes it will experience following surgery for weight loss.
Food to Limit or Avoid Before and After surgery for weight loss
While the types of foods each patient should avoid will depend on their particular body and how it processes and digests food, there is a list of foods that all weight loss surgery patients, whether gastric sleeve or any other surgery for weight loss, should always avoid. These foods include and are not limited to:
- Desserts and candy such as donuts or pastries;
- Fried foods;
- Fatty foods;
- Carbonated drinks (soda or sweetened Kool-Aid);
- Sugar (use sugar substitutes such as Splenda, Equal or Sweet & Low instead);
- Whole milk products (full fat cream, sauce or cheese);
- No fat or skin on meat or poultry;
- Fast food;
- High fat meats such as hot dogs, sausage or bacon;
- Limit added fats such as mayonnaise, salad dressing, butter or margarine;
- Snack foods such as tortilla chips, potato chips and other salty snacks.
Foods that are Safe to Eat
Some commonly consumed foods before and after surgery for weight loss include scrambled eggs (egg whites only), oatmeal, yogurt, low-fat cottage cheese, lean meat, fresh fruits and vegetables, sugar-free Jell-O, whole grains and protein shakes.Protein is a major component of the post gastric sleeve diet and helps the body to fat burn while on a low-fat diet. For gastric sleeve patients, protein shakes or protein-rich foods should be consumed at the right time in order to prevent blockages from occurring. Drink a lot of water in order to digest properly, however never drink water while eating as you will feel full fast and not consume enough nutrition.
