A new study found that para-athletes have lower nutritional knowledge compared to university student athletes, with 40% needing help with meal procurement and cooking. This highlights the need for targeted nutrition support and education for para-athletes.
The energy balance model fails to explain the biological causes of weight gain, whereas the carbohydrate-insulin model identifies excessive consumption of rapidly digestible carbohydrates as a key contributor to obesity. This perspective argues for a shift in focus from calorie restriction to dietary pattern change.
Researchers identified Sestrin as a key regulator of stem cell function and lifespan in response to dietary amino acids. Increasing Sestrin levels extended fruit fly lifespan and protected against negative diet effects.
Research involving 160 genetically distinct strains of fruit flies found that while dietary restriction extended lifespan, its effect on healthspan was less consistent. The study suggests that healthspan, rather than just lifespan, should be the primary focus for those seeking to improve aging outcomes.
Researchers found that switching to a rich diet after eating a restricted diet can decrease life expectancy and have negative effects on health. The study challenged the existing evolutionary theory, suggesting that dietary restriction triggers a survival strategy in humans and animals.
A new study found that ketogenic supplements can delay tonic-clonic seizures caused by high levels of oxygen, even in a normal diet. The supplements increased blood ketone levels, providing therapeutic ketosis and resistance to seizures.
Researchers found that dietary restriction maintains cellular fitness in intestinal cells, preventing age-related damage and leaky gut. A rich diet promotes excessive cell loss and permeability, linked to human conditions like inflammatory bowel disease.
Research links nucleolus to age-related pathways, finding that enlarged nucleoli correlate with shorter lifespans and reduced insulin signaling. A small nucleolus may extend lifespan by balancing cellular renewal and repair.
A recent study published in Acta Obstetricia et Gynecologica Scandinavica found that women with high physical activity levels had a reduced risk of acute cesarean sections. The Norwegian Fit for Delivery study also showed no other effects on labor or delivery outcomes.
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.
Researchers at Buck Institute find HIF-1 protein plays key role in pathway extending lifespan by dietary restriction. Under-expressing HIF-1 leads to increased lifespan even with nutrient-rich diet.
Researchers at the University of Washington have discovered a cell survival pathway that protects against degenerative diseases and promotes longevity. The study found that nematode worms live longer when their genetic make-up permits them to turn on this pathway under normal oxygen conditions.
Whitehead Institute researchers have identified a cellular pathway that determines whether cancerous tumors are susceptible to dietary restriction. The study found that permanently activated PI3K pathway allows tumors to grow independent of food consumption, while normal functioning leads to tumor shrinkage.
Resveratrol improves cardiovascular health, bone density, and motor coordination, while delaying cataracts and improving insulin sensitivity. The compound mimics the effects of dietary restriction without cutting calories.
Researchers have linked ribosomes and Gcn4 to the pathways related to dietary response and aging. The study found that mutations to the large ribosomal subunit led to increased lifespan, and treating cells with a drug specifically targeting the large subunits made them live longer.
A new eating model, ecSatter, suggests that managing weight and staying healthy requires a positive experience of eating. The model, developed by Ellyn Satter and Barbara Lohse, emphasizes permission and discipline to cultivate effective eating attitudes and behavior.
A new study published in Annals of Internal Medicine found that dietary counseling results in significant weight loss, with 10-15 pounds lost after one year. Moderate weight loss reduces diabetes, cholesterol, and blood pressure risk, making a lasting impact on overall health.
Researchers at OHSU found that mice consuming fewer calories experienced a boost in essential neurochemical glutamate, which reversed a Parkinson's-induced drop. The study suggests dietary restriction may be beneficial in early-stage Parkinson's disease.
Researchers found that Brazilian communities in coastal areas and the Amazon region have taboos on consuming certain fish species, especially predatory ones. These prohibitions are likely biologically adaptive, suggesting a link to toxic accumulation and health concerns.
A new study suggests that modest dietary restrictions before fecal occult blood testing (FOBT) for colon cancer screening do not significantly impact completion rates. The report also notes that more severe restrictions may reduce test completion, highlighting the potential benefits of simplifying dietary advice for FOBT testing.
