The gastric sleeve diet is less restrictive than the diets of other weight loss surgeries. On this diet, you can pretty much eat whatever you choose, however, for the diet to be successful you will want to watch the amount of fat, carbohydrates, and sweets that you eat. Certain spices might also need to be avoided. The typical postoperative diet for this type of weight loss surgery is divided into four phases.
The first phase of this diet is two days long and begins immediately after gastric sleeve surgery diet. This phase is called the liquid diet. While on this diet you will consume clear liquids such as broth, sugar-free jello, unsweetened tea, and juice as well as water.
The second phase begins immediately after the liquid phase. This phase is the pureed food diet. Your foods will need to be pureed in a little bit of water, milk or fat-free gravy. This diet will last for about two to three weeks. The soft food diet is the third phase and will last three to four weeks. Your food will need to be mashed well. On this diet, you can eat fruits, vegetables, and meats so long as they are soft and smashed with a fork really well.
The final phase of this diet is regular food. In this phase, you can eat just about anything. However, foods that were not good for you before the surgery such as fried foods, rich fattening gravies and sauces, high fat and high carbohydrates, chips, and sweets should be strictly avoided or eaten in very small amounts. Continuing to eat the foods you ate prior to surgery will only slow down or even stop your weight loss. Further, eating these foods may also make you gain any lost weight back.
This weight loss surgery is different from other weight loss surgeries in that it does not alter your digestive system as the RNY surgery does. Therefore recovery time is diminished and your body does not experience deprivation of nutrients and vitamins.
