Ghrelin

Ghrelin is a hormone produced in the stomach that plays a key role in regulating appetite and metabolism. It is often referred to as the “hunger hormone” because its levels increase before meals and decrease after eating, signaling the body to replenish energy stores.

Ghrelin acts on the hypothalamus, the part of the brain responsible for appetite and satiety.

Increased levels of ghrelin stimulate hunger, while its decrease helps to feel satiety.

In addition, ghrelin influences behavioral reactions associated with food seeking and motivation to eat.

Ghrelin and the Keto Diet

Following a ketogenic diet leads to changes in ghrelin levels. Due to stable blood glucose levels and increased fat consumption, feelings of hunger may decrease.

This is one of the advantages of the keto diet, as reduced appetite can aid in weight loss and maintenance.

Additional effects of the keto diet on ghrelin levels:

• Reduced fluctuations in blood glucose levels decrease ghrelin production stimulation.
• High fat and protein consumption increase the duration of satiety.
• Stable energy levels help avoid frequent snacking, which can stimulate ghrelin production.

Thus, the keto diet may contribute to normalizing ghrelin levels, which in turn helps control appetite and maintain a healthy weight.
