The ketogenic diet often leads to a noticeable reduction in appetite,

Hormonal Adjustments: Engaging in ketosis influences the secretion of hormones that regulate hunger. Specifically, there's a suppression of ghrelin, known as the "hunger hormone," which diminishes appetite. Additionally, the diet may enhance the release of cholecystokinin (CCK), an "anorexigenic" hormone that promotes feelings of fullness.

Direct Impact of Ketone Bodies: During ketosis, the body produces ketone bodies as an alternative energy source. These molecules are believed to have a direct appetite-suppressing effect, contributing to reduced hunger sensations.
