Some believe that calorie absorption can increase years out from weight loss surgery, when in fact it is the same absorption as when you first had weight loss surgery.
Your stomach gets more efficient at emptying food into the small intestine years out from weight loss surgery, which is why are able to eat more food at each sitting. It’s advised that bariatric patients never consume more than 6-8 ounces/meal to maintain weight. Over-consuming will lead to weight gain.
Dr. Steven C. Simper addresses the common concern of being able to eat more with this, “Every weight loss surgery patient will be able to eat more with time. With time the outlet of the of the Roux-en Y Gastric Bypass, Duodenal Switch, and Sleeve Gastrectomy will dilate, and the pouch will empty more quickly, allowing you to eat more.”
