| 17 | Rate is regulated to deliver nutrient to the small intestine at a roughly constant caloric rate, near 2 kcal per minute, regardless of meal composition. The regulator is feedback from nutrient sensing in the duodenum and ileum, mediated by cholecystokinin, [[Glucagon-like peptide-1|GLP-1]], peptide YY and neural reflexes — the so-called ileal brake.{{r|holst2007}} | 17 | Rate is regulated to deliver nutrient to the small intestine at a roughly constant caloric rate, near 2 kcal per minute, regardless of meal composition.

| + | 19 | Measurement methods are not interchangeable. Scintigraphy is the reference technique; the ¹³C-octanoate breath test is a validated surrogate; paracetamol absorption is convenient but measures liquid-phase emptying only. A study reporting "delayed emptying" without naming its method is not comparable with one that names a different method. | |
