Whole milk is likely to produce a longer-lasting sense of satiety compared to skim milk.
Cholecystokinin (CCK) is a hormone released by the small intestine, particularly in response to the presence of fats and proteins in the digestive system. It plays a role in stimulating the release of bile from the gallbladder and pancreatic enzymes, which are important for the digestion of fats and proteins.
When CCK is released into the bloodstream, it signals the brain's satiety center, leading to a feeling of fullness and satisfaction. Since whole milk contains a higher amount of fat compared to skim milk, it would result in a greater release of CCK due to the higher fat content. This increased release of CCK is likely to lead to a more prolonged sense of satiety when consuming whole milk compared to skim milk.
The fat content in whole milk contributes to slower digestion and absorption, which can lead to a more sustained feeling of fullness. However, it's important to note that individual responses to satiety can vary, and factors such as personal preferences, metabolism, and overall diet also play a role in how different foods impact feelings of fullness.
I hope this helped!
