When people think about weight loss after bariatric surgery, protein usually steals the spotlight. And while protein is essential, there’s another nutrient that deserves attention: fiber.
Fiber is the part of plant foods your body can’t digest, and it plays a big role in supporting long-term weight management—especially after bariatric surgery.
Why Fiber Matters After Surgery
-
- Satiety support: Fiber slows digestion and helps you feel fuller, longer. That’s important when your meal sizes are small—you want every bite to work for you.
- Blood sugar balance: High-fiber foods help stabilize blood sugar, reducing energy crashes and cravings that can make it harder to stick with your plan.
- Gut health: Bariatric surgery can change your digestion. Fiber feeds the “good” bacteria in your gut, supporting smoother digestion and better overall health.
- Weight regain prevention: By helping control appetite and cravings, fiber can be a quiet but powerful tool to protect your surgery results.
