Which assessment best explains why fats often increase perceived satiety relative to carbohydrate-rich foods?

• A. Fats slow gastric emptying and are energy-dense, providing sustained energy delivery and neurohormonal signals that increase the feeling of fullness compared with lower-energy-volume carbohydrate meals.
• B. Fats produce a sharp glycemic spike which directly triggers long-term satiety through sustained insulin suppression.
• C. Fat reduces satiety because it prevents cholecystokinin release and accelerates hunger signaling in the hypothalamus.
• D. Fats are absorbed in the mouth before digestion and therefore bypass digestive hormones, which paradoxically reduces satiety compared with carbohydrate meals.
