Changing the way you eat

Weight loss surgery works by reducing the amount of food you can eat. This means you will no longer be able to eat in the same way that you do now. Portion sizes will be much smaller and you will need to eat each meal slowly, sitting at the table in an upright position. You will need to chew much more thoroughly and restrict your fluid intake during meals.

There may be some foods that you may not be able to eat in the long term. These include white bread, boiled rice, pasta, meat chops, steak, nuts and fibrous fruits and vegetables such as oranges, pineapples, green beens and mushrooms. Eating too much, choosing the wrong type or texture of food, or eating too quickly could cause vomiting.

If you have had a gastric bypass you will need to take a chewable or dissolvable multi-vitamin every day for the rest of your life, to make sure you are receiving all the essential nutrients you need.

If you regularly organise meals for other family members, you may not be able to eat the same sort of food as them. Whilst they may eat their meal on a dinner plate, your portion will be small enough to fit on a tea plate. If you go out to dinner, your meal will be equivalent to a starter size rather than a main meal. And if you have takeaways, you will find these portion sizes are far too large, and you may not be able to eat the type of food available.

You will have regular one to one meetings with your dietician who will help you through any problems you are having and manage your diet with you.
