“The mTOR network is a highly conserved signaling pathway that serves as a "hub," integrating input from the cellular environment about nutrient, oxygen, and energy levels, ultimately driving fundamental cellular responses such as growth, proliferation, apoptosis, and inflammation.”

“Intermittent fasting has been shown to impact all these critical processes, from promoting angiogenesis to supporting metabolic shifts, positioning it as a potential tool in improving heart healing. The benefits are not merely theoretical; they’re deeply rooted in the biological stress responses that once helped our ancestors survive in challenging environments.”

“Exposure to environmental toxins – in the food we eat, the water we drink, and the air we breathe – is largely unavoidable. But monitoring our exposures and implementing diet and lifestyle strategies can help mitigate the risks associated with toxic exposures. In this Aliquot, Dr. Dale Bredesen, Dr. Michael Snyder, and I discuss ways to deal with our increasingly toxic environment.”

“Using rodent models in aging research provides the advantages of a controlled environment and a short lifespan, which increases the speed and quality of data collection. However, the ability to translate data from non-human animals to humans can be limited and the use of laboratory animals can raise ethical concerns.”

“A growing body of evidence suggests that fat plays a role in the activation of stem cells. Fasting generates molecules such as fatty acids, ketone bodies and glycerol, providing a favorable environment for stem cell activation and renewal.”

“The longevity-conferring effects of genetics, environment, and lifestyle appear to manifest early. For example, if a man has long sperm telomeres, his children will have long telomeres at birth.”

“In the past, fasting was imposed by the environment during times of famine. Dr. Longo proposes that the human body evolved a natural self-repair mechanism that is switched on during fasting and allows for the repair of damaged cells and organs.”

“For example, lab animals are raised and live in a somewhat sterile environment where they are fed on schedule. Generally, they lack ordinary exposure to diseases and accidents that can promote sudden stretches of disuse and consequent atrophy of muscles.”

“Early organisms existed in harsh environments with stressors such as food scarcity and predation. Adaptive responses to stressors such as increased neural activity while fasted, promoted survival.”
