Regulation of Food Intake

Regulation of Food Intake

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...

Hormonal Regulation

Hormonal Regulation

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.

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Primary Motives: Hunger and Thirst

Primary Motives: Hunger and Thirst

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 acts...

GPCRs Regulate Adenylyl Cylase Activity

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of cells.
Two...

Association Areas of the Cortex

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Summary

Short-chain fatty acids (SCFAs) may influence appetite. However, current evidence does not support a significant role for SCFAs in appetite regulation or energy homeostasis.

Area of Science:

Metabolic Science
Gastroenterology
Nutritional Science

Background:

Short-chain fatty acids (SCFAs), activated by G-protein coupled receptors (FFA2 and FFA3), are found in L-cells and adipocytes, potentially influencing satiety hormones like peptide YY and leptin.
SCFAs, such as acetate and propionate, were hypothesized to enhance food satiety and play a role in appetite regulation and energy homeostasis.
SCFAs can be administered directly in food or produced indirectly in the colon via fermentable carbohydrates.

Purpose of the Study:

To review existing studies on the effects of oral SCFA ingestion and colon-derived SCFAs on appetite regulation.
To evaluate the potential of SCFAs as a strategy for increasing the satiety-enhancing properties of food.
To determine if SCFAs play a role in appetite regulation and energy homeostasis.

Main Methods:

Literature review of studies investigating the effects of oral SCFA ingestion on appetite.
Analysis of research on colon-derived SCFAs from microfloral fermentation and their impact on satiety.
Examination of findings from studies on prebiotic inulin-type fructans and their effects on appetite.

Main Results:

A review of oral SCFA ingestion studies indicated that enhanced satiety might be attributed to palatability rather than a direct physiological effect.
Findings from investigations into the effects of prebiotic inulin-type fructans on appetite were mixed.
The overall data reviewed did not provide support for a role of SCFAs in appetite regulation.

Conclusions:

Current evidence does not support a significant role for SCFAs in appetite regulation.
The potential satiety-enhancing effects of SCFAs may be linked to factors like palatability rather than direct physiological mechanisms.
Further research is needed to clarify the complex relationship between SCFAs, gut hormones, and energy homeostasis.
