How does dietary fat impact feelings of satiety?

• A. It decreases feelings of fullness.
• B. It has no effect on appetite.
• C. It increases feelings of fullness.
• D. It only influences short-term hunger.

Answer: (C)

Dietary fat plays a significant role in promoting feelings of satiety, making it an important factor in appetite regulation. When fat is consumed, it slows down gastric emptying and prolongs the digestion process, which enhances the sensation of fullness. This delayed emptying allows for a longer period between meals, helping to prevent overeating. Moreover, fats stimulate the release of certain hormones, such as cholecystokinin (CCK) and peptide YY (PYY), which are associated with increased satiety. These hormones signal to the brain that the body has received enough food, thereby reducing the urge to eat. In contrast, other substances like carbohydrates, particularly simple sugars, tend to have a quicker impact on blood sugar levels, which can lead to faster feelings of hunger again. Understanding the role of dietary fat in satiety is essential for making informed choices about diet and managing hunger effectively.
