Proper nutrition after bariatric surgery is essential for healing, weight loss, and long-term success. Let’s break down what your diet should look like—and what supplements you’ll need.
1. Your New Diet: A 4-Phase Journey
Post-op eating happens in 4 stages:
- Clear liquids (Days 1–2)
- Full liquids (Days 3–14)
- Pureed foods (Weeks 2–4)
- Soft, then solid foods (Weeks 5 onward)
This helps your stomach heal and adjust to smaller portions.
2. Don’t Forget Your Vitamins
You’ll likely need:
- A daily multivitamin
- Calcium + Vitamin D
- Vitamin B12
- Iron (especially for menstruating women)
These prevent deficiencies due to reduced absorption.
3. Prioritize Protein
Aim for 60–80 grams of protein daily from sources like lean meats, eggs, Greek yogurt, or supplements. Protein helps with healing and muscle preservation.
4. Stay Hydrated (But Time It Right!)
Sip water throughout the day, aiming for 1.5–2 liters, but avoid drinking 30 minutes before or after meals to avoid overfilling your pouch.
Nutrition is a cornerstone of success after bariatric surgery. Follow your meal plan, take your supplements, and stay in touch with your care team for ongoing support.
