Summary
Calorie restriction and intermittent fasting offer health benefits like weight loss and improved body composition. This review examines their impact on human aging and longevity, drawing on limited but growing evidence.
Area of Science:
- Nutrition Science
- Gerontology
- Metabolic Health
Background:
- Excess calorie intake is linked to metabolic disorders and increased morbidity.
- Calorie restriction (CR) and intermittent fasting (IF) show promise for weight management and body composition.
- While animal studies suggest CR/IF enhance longevity and slow aging, human data remain limited.
Approach:
- This review critically evaluates existing research on dietary interventions.
- Focuses on the impact of calorie restriction and intermittent fasting on age-related decline.
- Synthesizes evidence regarding human longevity and aging processes.
Key Points:
- Dietary interventions like calorie restriction and intermittent fasting can lead to significant weight loss.
- Improved body composition is a notable benefit associated with these eating patterns.
- Evidence suggests potential for increased longevity and slowed aging, particularly in animal models.
Conclusions:
- Calorie restriction and intermittent fasting show potential for mitigating age-related decline.
- These dietary strategies may influence human longevity, warranting further investigation.
- Understanding the precise mechanisms and long-term outcomes in humans is crucial.

01:37Mitochondria
13.4K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

01:19Regulation of Metabolism
9.0K
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...

01:30Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

01:24Metabolic States of the Body: Fasting and Starvation
2.8K
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...

02:15Replicative Cell Senescence
3.5K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

00:51Energy Budgets
9.8K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
