Calorie restriction: a double-edged path to aging and healthspan

This Nature Aging review examines how different dietary restriction (DR) strategies—caloric, protein, fasting, and time-restricted regimens—affect aging and disease across mammals, highlighting common longevity pathways (autophagy, NAD+, AMPK, mTOR) and potential DR mimetics (FGF21, sirtuins, GLP-1). DR can improve healthspan and delay cancer, cardiovascular disease, and neurodegeneration in preclinical models, but effects vary by genotype, sex, species, and age at initiation, and DR may impair immune function and wound healing. The article discusses physiological adaptations (hunger, body temperature, fat loss) and translational challenges to humans, emphasizing the need for personalized approaches and cautious development of DR mimetics.

Scientists Extend Mouse Lifespan by 33% by Removing a Key Amino Acid

Scientists found that reducing the amino acid isoleucine in mice diets extended their lifespan by about 33%, improved health markers, and decreased cancer incidence, suggesting that targeting specific nutrients could promote longevity without strict calorie restriction.

New Longevity Drug Shows Promise Without Diet Restrictions

A new study finds that Rapamycin, originally an immunosuppressant, extends lifespan in eight vertebrate species as effectively as dietary restriction, while Metformin shows no clear benefit, highlighting Rapamycin's potential in aging research.

Rapamycin and Calorie Restriction: New Insights into Extending Lifespan

A meta-analysis suggests that rapamycin may extend lifespan in animals similarly to dietary restrictions, unlike metformin, but human trials are needed to confirm its effects and safety for longevity in people.

Rapamycin and Blood Pressure Drugs Show Promising Anti-Aging Benefits

A new study shows that rapamycin extends lifespan almost as effectively as calorie restriction in animals, unlike metformin, which shows no clear benefit. While promising, more research is needed to confirm safety and efficacy in humans, and current evidence is primarily from animal studies.

"Reduced Amino Acid Intake Extends Mouse Lifespan by 33%"

Research in mice suggests that restricting the essential amino acid isoleucine in their diet can increase lifespan and healthspan, reduce frailty, and promote leanness and glycemic control. Male mice experienced a 33% increase in lifespan, while females had a 7% increase. The mice also showed improvements in various health measures. However, applying these findings to humans is complex, as diet is a complex chemical reaction and other dietary components may be involved. The study suggests potential anti-aging effects in humans through isoleucine restriction, but further research and potential interventions, such as an isoleucine-blocking drug, are needed.

"Discover the Diet Gene That Extends Lifespan and Slows Brain Aging"

A study by the Buck Institute has found that dietary restriction, such as intermittent fasting and low-calorie diets, can significantly slow brain aging and extend lifespan by enhancing the activity of the OXR1 gene, which protects against neurodegenerative diseases. The gene plays a crucial role in maintaining the retromer pathway, essential for recycling cellular proteins and lipids in neurons. The research suggests that dietary choices have a profound impact on cellular health, brain functionality, and longevity, with potential implications for future therapeutic developments.

"Dietary Restriction's Impact on Lifespan and Brain Health Unveiled by Scientists"

New research identifies the OXR1 gene as crucial for extending lifespan and ensuring healthy brain aging in response to dietary restriction, shedding light on the gene's role in neuronal protection and retromer function preservation. The study, conducted on fruit flies and human cells, suggests potential new treatments for neurodegenerative diseases and strategies for healthy aging. The findings also reveal a detailed cellular mechanism of how dietary restriction can delay aging and slow the progression of neurodegenerative diseases, offering potential therapeutic targets to enhance brain resilience and extend lifespan.
