Having weight loss surgery means making a lifelong commitment to following a carefully prescribed program of good nutrition and regular exercise.


Diet Stages After Weight Loss Surgery

Dedicating yourself to a healthy lifestyle after weight loss surgery helps you achieve and maintain weight loss as safely as possible. Because weight loss surgical procedures change your digestive system, it is important to select the right foods and fluids, in the appropriate amounts, to ensure proper nutrition following your operation.

There are also eating techniques you must learn to aid in digestion, such as eating slowly and chewing thoroughly.

There are five diet stages after weight loss surgery. As a general rule, you will do best if you avoid foods high in sugar and fat, and eat foods that contain high-quality protein.

Understanding Bariatric Nutrition

If you decide to have weight loss surgery, you will meet with a dietitian before your procedure and throughout your recovery period. Your dietitian will provide an individualized nutrition plan to help you learn what to eat and drink, which will help you reach and maintain a healthy weight.

After weight loss surgery, your small stomach pouch limits the amount you can eat at one time, and the types of food you can comfortably eat. Some patients may not be able to tolerate foods such as raw vegetables, bread, pasta, or red meat.

It is important to understand that over time, overeating is still possible and can cause your small stomach pouch to stretch. While weight loss surgery does help most patients keep overall calorie intake in check, leading to weight loss and the maintenance of a more healthy body weight, you can regain weight if you:

  • take in a lot of calories from unhealthy foods
  • snack/graze frequently
  • eat large meals
  • are not active on a regular basis

Seeing your dietitian as scheduled and understanding your nutrition plan is essential to success after weight loss surgery.
