After clear liquids in Phase 1, Phase 2 - the full liquids and purees diet - advances your bariatric recovery by introducing thicker, nutrient-dense options to continue healing and muscle preservation. This stage, typically lasting 2–4 weeks (starting around day 7–14 post-surgery and up to week 4–6 at home), emphasizes high-protein intake (60–80g daily) while keeping textures smooth and easy to digest, bridging the gap to solid foods.
Key Guidelines for the Full Liquids & Purees Phase:
-
Allowed Foods & Drinks: Opaque liquids that liquify at body temperature, plus smooth purees (applesauce consistency, no chunks). Prioritize protein sources. Examples include:
- Low-fat milk or lactose-free alternatives
- Protein shakes or smoothies (whey/casein-based, 15-20g protein/serving)
- Greek yogurt (plain, low-fat; strained if needed)
- Pureed lean proteins (blended chicken, turkey, fish, eggs, or cottage cheese)
- Vegetable soups (blended, low-sodium; e.g., butternut squash, carrot)
- Fruit purees (unsweetened applesauce, mashed bananas; limited portions)
- Protein-fortified puddings or custard (sugar-free)
- Protein & Fluid Goal: Aim for 60-80g protein daily (start with shakes if needed) and sip 64 oz total fluids (1-2 oz every 15 minutes while awake, separate from meals by 30 minutes). Track to support healing and prevent constipation.
- Avoid: Chunky textures, high-fat creams, sugary items (>5g/serving), carbonated drinks, alcohol, caffeine, or fibrous veggies/fruits (e.g., raw or stringy produce); nothing that requires chewing.
- Tips for Success: Eat 4-6 small "meals" (2-4 oz each) over 20-30 minutes; blend with water/milk for smoothness; rotate flavors to stay motivated; continue chewable multivitamins with calcium. Advance to Phase 3 (soft foods) when tolerating 60g+ protein and 64 oz fluids comfortably.
This transitional phase boosts nutrition and energy while protecting your pouch, embrace the variety for steady progress. Stay consistent for smoother sailing ahead. Always personalize with your medical team’s advice.
Phase 2 is where real nutrition begins. focus on protein to heal and thrive. Small, frequent sips and purees prevent setbacks; patience here pays off in lifelong habits.
