Metabolic States of the Body: Fasting and Starvation

Metabolic States of the Body: Fasting and Starvation

During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

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...

Regulation of Metabolism

Regulation of Metabolism

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...

Metabolic States of the Body: The Postabsorptive State

Metabolic States of the Body: The Postabsorptive State

The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Energy Balance

Energy Balance

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...

Calorimetry

Calorimetry

When objects at different temperatures are placed in contact with each other but isolated from everything else, they attain thermal equilibrium. A container that prevents heat transfer in or out is called a calorimeter, and the use of a calorimeter to make measurements is called calorimetry. Generally, these measurements involve heat or specific heat capacity. The term "calorimetry problem" is used for any problem where the specified objects are thermally isolated from their surroundings. An...

Summary

Caloric restriction, a 10-30% calorie reduction, extends lifespan and prevents age-related diseases in many species. Its mechanisms involve metabolic rate changes and key molecular pathways like insulin signaling and Sirtuins.

Area of Science:

Gerontology
Metabolism
Molecular Biology

Background:

Caloric restriction (CR) is a proven intervention for extending lifespan and healthspan.
CR involves a 10-30% reduction in calorie intake compared to ad libitum feeding.
CR's benefits are observed across diverse species, from yeast to rodents.

Purpose of the Study:

To review the current understanding of caloric restriction.
To elucidate the underlying mechanisms of CR's health benefits.
To explore the molecular pathways involved in CR's effects.

Main Methods:

Review of existing scientific literature on caloric restriction.
Analysis of studies investigating CR's impact on metabolic rate and oxidative stress.

Main Results:

CR reliably extends longevity and prevents age-related disorders.
Potential mechanisms include altered metabolic rate and reduced reactive oxygen species.
Key pathways mediating CR benefits involve insulin/IGF signaling, mTOR, AMPK, and Sirtuins.

Conclusions:

Caloric restriction is a powerful tool for promoting longevity and healthspan.
Understanding CR's molecular underpinnings is crucial for therapeutic applications.
Further research is ongoing to fully define CR's complex mechanisms.
