Peptide YYfoods Peptide YY (PYY) is a fascinating gut hormone that plays a significant role in regulating appetite, digestion, and even energy expenditureWhy some digestive pain is amplified by hormones. Produced primarily in the L cells of the small intestine, particularly the ileum and colon, PYY is secreted in response to nutrient ingestionEffect of Peptide YY3–36 on Food Intake in Humans. Its primary function is to act as an acute satiety signal, essentially telling your brain that you are full. This mechanism is crucial for controlling food intake and maintaining energy balance.15小时前—Peptide YY (PYY) – a hormone made in the gut thathelps control appetite and gut movement, and now appears to shape pain sensitivity. · Short- ...

Research indicates that the consumption of protein notably boosts PYY levels, suggesting a direct link between dietary protein and feelings of fullness. This phenomenon is thought to contribute to reducing hunger and promoting weight loss, as observed in various experimental studies. PYY's influence extends beyond simply curbing appetite; it also plays a part in regulating body weight by potentially increasing energy expenditure, although the precise mechanisms are still under investigation.Peptide YY - an overview

How PYY Works to Control Appetite and Digestion

When PYY is released into the bloodstream after a meal, it travels to the brain and interacts with specific receptors, primarily the Y2 receptor in the arcuate nucleus of the hypothalamus. This interaction helps to reduce food intake by suppressing appetite-stimulating signals作者：JA Cooper·2014·被引用次数：101—Peptide YY(PYY) is an acute satiety signal released upon nutrient ingestion and has been shown to decrease food intake when administered .... Studies have shown that PYY(3-36), a specific form of the hormone, acts via these hypothalamic Y2 receptors to physiologically regulate food intake.

Beyond its central effects on appetite, PYY also influences the digestive system directly. It acts as a strong stimulator of absorption in the small intestine, ensuring nutrients are efficiently processedPeptide YY Is a Regulator of Energy Homeostasis in Obese .... Furthermore, PYY is known to cause reduced gastric emptying and delayed gastrointestinal transit. This slowing down of digestion contributes to a prolonged feeling of fullness and can help manage blood sugar levels.Peptide YY (PYY), human | Gut Hormone

In conditions like Type 2 Diabetes, PYY's role is particularly interesting.PYY is a short-term appetite regulatorof the neuropeptide Y family, released in proportion to meal energy content and shown to reduce food intake in rodents ... It promotes glucose-dependent insulin secretion, suppresses glucagon output, and as mentioned, slows gastric emptying. These effects collectively contribute to better glycemic control.

PYY and Weight Management: A Complex Relationship

The connection between PYY and obesity is an area of significant research. Studies have observed that individuals with obesity often have lower fasting levels of PYY and an attenuated release of the hormone after meals. This reduced PYY signaling may contribute to increased hunger and overeating, potentially playing a role in the development or maintenance of obesity. Therefore, understanding how to increase PYY levels or enhance its signaling is a key focus in the search for effective weight management strategies. Some research even suggests that PYY could be a target for interventions aimed at removing the cause of obesity rather than just treating its symptomsThe principal effect of PYY isto suppress appetite. Obese people have lower fasting levels of PYY and attenuated postprandial PYY release associated with ....

The hormone peptide YY is not just an appetite regulator; it's also recognized as a short-term appetite regulator of the neuropeptide Y family. Its release is proportional to the energy content of a meal, and it has been shown to reduce food intake by a third in both normal-weight and obese individuals2025年8月6日—PYY is involved in energy intake through gastrointestinal digestion14, 15 , where it inhibits the orexigenic neuropeptide Y neurons in the .... The potential therapeutic applications of PYY, particularly PYY(3-36), are being explored, with compounds like synthetic human PYY 3-36 being evaluated as a compound being evaluated for the treatment of obesity due to their ability to reduce appetite and increase satiety作者：NT Nguyen·2025—It promotes glucose-dependent insulin secretion, suppresses glucagon output, slows gastric emptying, and decreases food intake—all in a glucose-dependent ....

Beyond Appetite: Other Roles of Peptide YY

While appetite regulation is PYY’s most well-known function, emerging research suggests it has broader implications.Triple–Hormone-Receptor Agonist Retatrutide for Obesity Recent findings point to a role for PYY and the neuropeptide Y (NPY) receptor systems in the control of beta cell survival, which is critical for insulin production. Additionally, PYY appears to help control appetite and gut movement, and now seems to shape pain sensitivity.Factors affecting circulating levels of peptide YY in humans It can mediate its effects through the Neuropeptide Y receptors and is involved in energy intake through gastrointestinal digestion, where it inhibits orexigenic neuropeptide Y neurons.

Furthermore, there's intriguing evidence suggesting that Peptide YY inhibits transcription and replication of hepatitis B virus by suppressing promoter/enhancer activity, indicating potential antiviral properties.2007年10月21日—Peptide YY (3-36), a synthetic human PYY 3-36,is a compound being evaluated for the treatment of obesity.

Factors Influencing Peptide YY Levels

Several factors can affect circulating PYY levels. As mentioned, dietary protein is a significant stimulator. However, other factors can also play a roleWhat are PYY modulators and how do they work?. Understanding these influences is key to potentially modulating PYY levels for therapeutic benefit.

In summary, peptide YY is a vital gut hormone with a multifaceted role in human physiology. Its primary function as an appetite suppressant and regulator of food intake makes it a crucial player in maintaining energy homeostasis and a potential target for interventions related to weight management and metabolic health.
