Phase II Full Liquid Diet

1. On discharge from the hospital after weight loss surgery, you will start the full liquid diet.

2. You will stay on the full liquid diet for 1-2 weeks unless directed otherwise by the General Surgeon and Registered Dietitian.

3. To prevent nausea and vomiting, DRINK LIQUIDS SLOWLY. Sip ¼ cup (2oz) of liquid over 30 minutes. You do NOT have to finish everything. When you feel full STOP!

4. Drink at least 6-8 cups of water or low calorie drinks between high protein beverages. Remember to avoid carbonation, caffeine, and citrus.

5. Take your prescribed multi-vitamin/mineral supplements and calcium as instructed. (refer to page titled “Vitamin and Mineral Supplements” for a list of all mandatory supplements)

6. Make sure you keep track of the kind and amount of high protein beverages you drink. Remember, you need a minimum of 60 grams of protein each day.

The following are examples of protein sources that should be included on the Full Liquid Diet:
1 cup Fat free or 1% milk = 8gr protein
1 cup Soy milk or lactose-fee milk (Lactaid ®or Dairy Ease®) = 8gr protein
No-sugar added breakfast drink made with fat free or 1% milk (Carnation Instant Breakfast®) = 12gr protein
Strained cream soup made with milk (no tomato, no mushroom or corn pieces) = 8gr protein
Commercial supplements as suggested by the surgeon or RD (refer to list on page titled “Protein Supplements”)


*To help boost protein intake add non-fat powdered milk to the above list of liquids.
