Post Bariatric Surgery Diet

After your bariatric surgery, it will be necessary for you to make significant changes in your diet. While adjusting the quantities and types of food you ate may have been difficult in the past, your surgery will help you to make these changes more easily. It is important to remember that your bariatric surgery will not help you to lose weight unless you make these dietary changes. Weight loss success is up to you and your willingness to follow nutrition and activity recommendations.

In this section of our bariatric surgery guide, we discuss your diet in the immediate post-operative phases and then the life-long phase. What we are discussing is not a diet. It is a new way of thinking about and relating to food. For many people their relationship with food changes from living to eat to eating to live.

Eating after Bariatric Surgery

You will be provided with detailed instructions about what and how to eat in the days leading up to your surgery and progressing your diet after surgery. The length of time you spend progressing your diet from clear liquid to your lifelong diet varies depending on whether you have had an adjustable gastric band or a gastric sleeve bariatric surgery.

Regardless of the weight loss surgery you have had, there are certain tips that you should keep uppermost in your mind every time you eat.

  • Take your time progressing through each phase to ensure you are comfortable and tolerating your food properly.
  • Nausea and vomiting is usually an indication that you are eating too fast, eating the wrong types of food or drinking with your meals. It can also be an indication of an issue with your surgery that should be looked at so always report to us if you have a problem with nausea and vomiting.
  • Eat your protein first.
  • Don’t drink with meals.
  • Limit starch intake. Avoid bread, rice and pasta.
  • Avoid processed foods and refined sugars
  • Eat fresh vegetables liberally and fresh fruit in moderation
  • Use the plate method. One quarter protein, one half vegetables and one quarter starchy vegetables and fruit.
  • Measure your portions
  • Eat slowly to give your stomach time to register fullness. Remember that the sensation of being full may be different after surgery. Take time to learn the new sensation.
  • Sip water throughout the day but stop drinking 15 minutes before and resume 30 minutes after your meal.
  • Do not drink your calories. Drink water or other calorie-free beverages.
  • Do not drink carbonated beverages.
