Shifting nutrient absorption to the distal small intestine (ileum) significantly increases post-prandial GLP-1 and PYY secretion, improving glucose control and contributing to weight loss, as seen in bariatric surgery and with certain enzyme inhibitors.
Bariatric surgery works partly by forcing food to be digested further down the intestine, which triggers a strong hormone release (GLP-1/PYY) that helps control blood sugar and appetite. Some diabetes medications (like acarbose) mimic this by slowing digestion. This suggests that how and where food is absorbed matters as much as what is eaten.
Shifting nutrient absorption to the more distal intestine (ileum) results in a different post-prandial hormonal profile, with prolonged elevation of plasma GLP-1/PYY levels, which contributes to the metabolic improvements seen after bariatric surgery and pharmacological inhibition of nutrient digestion.
Why this rating
Supported by bariatric surgery case studies, mouse models, and known effects of alpha-glucosidase inhibitors.
