You’ll have to start eating differently after having weight loss surgery, but that doesn’t mean you’ll have to give up all your favorite foods. Let’s start by talking about how things will be different.
Your stomach acts as a holding tank for food and beverages and as a strong muscle that grinds and churns your food, helping with digestion. Depending on the procedure, weight loss surgery either removes a large portion of your stomach or significantly restricts access to your stomach. And, as you can imagine, reducing the capacity of your stomach makes it much harder for it to do its job.
To help your stomach adapt to this increased workload, you’ll be introduced to a staged diet that features gradual changes in food textures. You’ll drink protein shakes for two weeks and then slowly advance to soft foods for four weeks. With time, you should be able to tolerate a variety of textures, as long as you eat slowly and chew carefully. For more information on the post-operative (and pre-operative) diet, see the Nutrition Resources section of our Center for Metabolic and Bariatric Surgery site.
Surgery + You = Weight Loss
Weight loss surgery alone doesn’t ensure that you’ll lose weight and keep it off. You also will need to change the way you eat for the rest of your life in order to be successful. This means reducing your calorie intake by eating small portions and avoiding calorie-packed foods and beverages. Fortunately, your modified stomach is a built-in portion control tool, so all you have to do is put healthy foods on your plate and stop when your stomach is full.
