Nutrition Guidelines after Gastric Bypass, Gastric Band

1. Diet Progression
The weight loss surgery diet is divided into four phases. The diet progression is outlined below:
Phase 1: Clear Liquids (1-2 meals)
- For 1-2 meals after surgery you will be given clear liquids such as water, broth, a small
amount of unsweetened juices, diet Jell-O and diet drinks to see how you tolerate eating.
- Sip slowly and pay attention to your feelings of fullness.
Phase 2: Blended/Pureed Food (3 weeks)
- For approximately 3 weeks after surgery, you will need to eat blended or pureed foods.
- All the food you eat should be the consistency of thin, smooth applesauce or yogurt.
- Put cooked foods in a blender, then add liquid such as skim milk, broth, fat free gravy or low
fat creamy soup and blend until smooth.
- Eating solid foods too soon will put pressure on the staple line and may cause breakage or
leaking.
