Cholecystokinin (CCK) levels increase in the bloodstream within 15 minutes of starting a meal, remaining elevated for up to three hours. This rapid postprandial response is a key reason why cholecystokinin is called an appetite suppressant, as it triggers a powerful cascade of signals that promote satiety and curb further eating.

Chronic lack of sleep has been associated with altered leptin levels and function, impacting appetite regulation. Discover the natural, science-backed methods for improving your body's response to this key satiety hormone, answering the question, 'How do I raise my leptin levels?'.

Leptin is a hormone produced by your body's fat cells, and the amount of leptin in your blood is directly related to the amount of adipose tissue you have. However, you cannot directly find leptin in any food or supplement, as it is produced endogenously. The key is to support your body's natural leptin production and sensitivity through diet and lifestyle.

Peptide YY (PYY) is a 36-amino acid peptide released by specialized L-cells in the gastrointestinal tract in response to food intake. The primary effects of peptide YY are to reduce appetite and slow gastric motility, contributing to the feeling of fullness after a meal. This hormone plays a critical role in the body's energy homeostasis and is a subject of extensive research for its therapeutic potential in combating obesity.

Multiple studies have demonstrated that when peptide YY (PYY) is infused into humans, it significantly decreases appetite and reduces food intake. This contradicts the idea that the hormone promotes hunger, confirming its role as a key satiety signal in the body.

Cholecystokinin (CCK) is a crucial gastrointestinal hormone, and research has consistently demonstrated its role in digestion. Produced in the small intestine, it is widely known for its potent ability to decrease appetite by signaling the brain to promote feelings of fullness. This article will delve into the mechanisms behind CCK's function and its significant impact on satiety and appetite regulation.

Amylin is a hormone co-secreted with insulin by the pancreas after meals, with a primary physiological role in regulating blood glucose. Crucially, it also acts as a potent satiety signal to the brain, influencing how much and how often we eat, directly impacting overall food intake.
