Summary
Appetite regulation is complex, involving many factors beyond just hormones like ghrelin, peptide YY (PYY), and cholecystokinin (CCK). These hormones do not always directly correlate with hunger or fullness, indicating a more intricate process of food intake control.
Area of Science:
- Physiology
- Neuroendocrinology
- Behavioral Science
Background:
- Appetite control is a complex process influencing feeding behavior and energy balance.
- It is modulated by behavioral, psychological, and neuroendocrine factors.
Purpose of the Study:
- To explore the intricate mechanisms of appetite control and food intake.
- To investigate the relationship between specific hormones and subjective feelings of hunger and fullness.
Main Methods:
- Literature search conducted on EMBASE, OVID, PubMed, and MEDLINE databases.
- Included English-language articles published between 2002 and 2015.
Main Results:
- Elevated peptide YY (PYY) and cholecystokinin (CCK) levels, alongside lower ghrelin levels, do not consistently correlate with satiety or reduced energy intake.
- This suggests appetite control is a highly intricate process.
Conclusions:
- Food ingestion triggers numerous physiological, hormonal, social, and psychological responses.
- Ghrelin, PYY, and CCK are key components, but only part of the complex appetite regulation system.

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

1.5K
Hunger and thirst are fundamental physiological drives crucial for maintaining homeostasis and ensuring the survival of both humans and animals. These drives are regulated through complex interactions between the brain, hormones, and sensory receptors.
Hunger arises when the brain detects changes in the body's nutrient levels, including glucose, lipids, amino acids, and hormones such as ghrelin and leptin. The hypothalamus plays a central role in hunger regulation. The lateral hypothalamus...

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.
