After undergoing bariatric surgery the person needs to drink a liquid diet for about 15 days, and then can start the pasty diet for about another 20 days. After this time solid foods can be re-introduced bit by bit, but food usually only returns to normal, about 3 months after surgery.
This time of adaptation is very important because the person's stomach becomes very small and only fits about 200 ml of liquid, which is why the person slims fast because even if you want to eat a lot you will feel very uncomfortable because literally the food it will not fit in the stomach.
How to Make a Net Diet
The liquid diet starts right after surgery and lasts from 1 week to 15 days. In this period, food can only be consumed in liquid form in small volumes, about 100 to 150 ml, with about 6 to 8 meals a day, with an interval of 2 hours between meals. Foods have to be ingested slowly, and it can take up to 40 minutes for a glass of soup, for example.
The foods allowed in this liquid diet are teas, fruit juice and natural vegetables, soy drink, coconut water, homemade broths of meat, chicken, fish or vegetables. But it is also important to drink water throughout the day in small amounts and take the supplements prescribed by your doctor to ensure the amount of vitamins your body needs.
How to Make the Pasty Diet
The pasty diet should start about 15 days after surgery, and the person may eat only pasty foods such as vegetable creams, porridges, cooked or raw fruit purees, legume purees, protein purees or fruit vitamins whipped with juice of soy or water, for example.
