Where Healing, Teaching and Discovery Come Together


Pre-Op Diet

Pre Bariatric Surgery Diet

On average, it takes about 8-12 weeks from the time a person decides to have weight loss surgery to their actual surgery date. This is a perfect time to begin working on nutrition and lifestyle changes! These changes will help you prepare for the lifestyle transition that comes after surgery and will help make your surgery and the journey ahead go more smoothly.

Bariatric surgery requires you to make permanent changes in your diet and lifestyle.  At your first meeting with the bariatric surgery team, you will discuss setting a pre-surgery weight loss goal—losing 5% of your weight before surgery can lower your risk of complications by decreasing the size of your liver and reducing the amount of abdominal fat, making your surgery faster and safer. Before surgery, you will meet with a registered dietitian (RD) to learn about diet and behavior changes. The dietitian will work with you to develop an eating plan to help you eat smaller portions and make healthier choices before surgery. This will help you take the first steps toward the diet changes that will be required for the rest of your life following bariatric surgery as well as help you lose weight before surgery.

Your initial meeting with the dietitian will address:

  • Eating small, frequent meals
  • Staying hydrated before and after bariatric surgery
  • Getting enough protein
  • The importance of choosing low-fat, low-sugar foods
  • Mindful eating
  • Preventing vitamin and mineral deficiencies after bariatric surgery
  • Diet progression after bariatric surgery
