As soon as your stomach is full, your body receives a signal that you have had enough. However, the recognition of this signal requires some time. If you eat very quickly, you may eat more than you need. This may cause nausea and vomiting. Take your time at meals. Try to recognize the feeling of satiety and then stop eating immediately.

Your surgery will only be successful if you consume solid foods. If you drink while eating, the food that you have consumed will become liquid and the effectiveness of your surgery will be decreased enormously. You must not drink anything for one to two hours after every meal. This allows you to maintain the feeling of satiety for the longest possible time.

After a meal, do not eat anything until your next meal. Snacking between meals is one of the principal reasons why attempts to lose weight fail. It is very important to break this habit. Those patients with appropriate levels of "satiety" do not feel hungry between meals. If you do not experience this feeling, you should inform your surgeon.

Independently from the type of surgery performed, you should only be able to eat small amounts of food, so it is important that your meals are as healthy as possible. Do not load your small stomach bag with “junk” or unhealthy food lacking in vitamins and other important nutrients. Your food must be rich in proteins and vitamins. Vegetables and fresh fruit, meat and cereal are good choices. Foods rich in fat and sugar are not. You can eat apples and oranges, but try to avoid orange and apple juice. Solid food is more important than liquid food. Liquid foods pass through the exit of the stomach very quickly and will not make you feel satisfied.

For example, asparagus contains a lot of fiber that can block the stoma or the exit of the stomach. This is because this food cannot be chewed sufficiently to cut it up into small pieces, and your saliva cannot break it down. Fibrous foods should be avoided. If you want to occasionally eat asparagus or other fibrous foods, you must be sure to cook them well, cut them into very small pieces and chew thoroughly.

If you lose weight, your fat content will drop. This produces waste material. You will need to drink large amounts of liquid every day to urinate more and excrete these waste products from your body. Individual needs vary, but you should drink at least 6 to 8 glasses of water a day. Remember, you must only drink water, tea or coffee (without milk, cream or sugar). Moreover, you must keep your food and drinks completely separate during the day.

This rule is as important as the other nine. As physical exercise consumes energy and burns calories, it is very important for successful weight loss.
Exercise can help you to improve your general health. Your size can make it hard for you to exercise as much as you should. But get started, even if initially it is very little. The more weight you lose, the easier it becomes. Start with simple exercises such as walking and swimming. Gradually expand your program until you include more vigorous forms of exercises, such as cycling, jogging and aerobics.
Increase your level of activity in the course of your daily activities. For example, remain standing instead of sitting down, walk instead of standing, go out instead of staying at home, walk instead of driving your car, walk up the stairs instead of taking the elevator. Remember that you should always ask your doctor about the type and amount of exercise most convenient for you.

Note: Although these rules restrict your consumption of food and the types of meals that you can eat, keep your diet as varied and balanced as possible.
The previously described rules are based on the recommendations of Professor P. O'Brien, of Melbourne, Australia, Dr. R. Weiner, of Frankfurt, Germany, and J. Gabrielle Rabner, MS RD, of New York, United States.
