Hermaphrodite worms live up to two weeks longer on dietary restriction, while males show no change despite genetic mutations in a key sex-determination pathway. The study suggests hermaphrodites have evolved to conserve energy until favorable conditions return.
Researchers found that restricting diet or using genetic manipulation to mimic it can maintain youthful mitochondrial networks, increasing lifespan. These youthful networks also improve fat metabolism by communicating with peroxisomes.
A new study reveals that dietary restriction improves learning in worms by depleting a specific amino acid metabolite. The researchers used the nematode worm Caenorhabditis elegans to test how food deprivation affected learning and found that restricted access to food increased learning by reducing kynurenic acid levels.
Research reveals that dietary restriction enhances the expression of circadian clock genes in fruit flies, improving fat metabolism and extending lifespan. The study suggests a potential target for drug development to promote healthy aging.

Researchers at Harvard School of Public Health identify hydrogen sulfide as a key molecule responsible for the health benefits of dietary restriction, linking it to increased lifespan and protection against tissue damage. The findings suggest that restricting specific amino acids can increase H2S production, leading to these benefits.
Rapamycin, an immunosuppressant approved for use about 15 years ago, appears to mimic the ability of dietary restriction in helping animals live both longer and healthier. New research identifies why rapamycin increases insulin resistance and suggests a combination with metformin may provide benefits without unwanted side effects.
A new evolutionary theory proposes that consuming a very low-nutrient diet can increase human lifespan. Laboratory animal studies have shown that severely restricted food intake reduces the incidence of diseases and increases lifespan, likely due to increased cellular recycling mechanisms.

A study led by UC Irvine researchers found that the herbal extract Rhodiola rosea increases fruit fly lifespan by an average of 24 percent. The extract works independently of dietary restriction and affects different molecular pathways. Additionally, it delays physical performance loss and extends the lives of old flies.
Dietary restriction in flies prolongs life by enhancing fat metabolism and increasing physical activity, critical for extending lifespan. Blocking fat synthesis negates the effect of dietary restriction.
A new mouse study has found that maintaining body fat rather than losing it can lead to longer lifespan in mice. The findings contradict the widely held view that weight loss is essential for extending life, suggesting that individuals with difficulty losing weight may benefit from dietary restriction more.
A new study from the Max Planck Institute for Biology of Ageing suggests that a combination of proteins is crucial for healthy aging, not reducing overall calorie intake. Researchers found that manipulating the diet of female fruit flies showed varying results depending on the type and amount of amino acids consumed.

A new study funded by the Wellcome Trust suggests that getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories. Researchers found that varying the amount of amino acids in a diet can affect lifespan and fertility, with certain amino acids being crucial to maximising both.
Researchers found that a lower-calorie diet slows development of age-related conditions such as Alzheimer's disease, while a high-calorie diet accelerates oxidative stress. Dietary restriction activates transcription factor CBP, which regulates cellular function.
