“Dr. D'Agostino cautions against confusing a Westernized obesogenic high-fat diet with a ketogenic diet. In a well-designed preclinical study, researchers fed mice a cyclic ketogenic diet starting at midlife and observed improved healthspan, cognition, and brain function.”

“Dr. Patrick begins with a prospective Finnish cohort in which men reporting four to seven sauna sessions per week had lower dementia and Alzheimer's disease incidence than men reporting one session. The study is observational, male-only, and cannot prove that sauna caused the lower risk.”

“Even though the primary endpoints failed (NR did not improve insulin sensitivity or weight loss), he notes a meaningful signal in reduced liver fat—a 2% decrease in the NR group compared to a 0.2% reduction in the placebo group, a difference that didn't reach statistical significance, likely because subjects weren't randomized by liver fat and variability was high.”

“Drinking two to three cups per day is linked to roughly a 60% reduced risk of developing diabetes, a statistic that highlights coffee's robust metabolic benefits that arise from its ability to activate AMP-activated protein kinase (AMPK), a critical regulator of cellular energy metabolism.”

“Other hormetic responses to cold exposure include increased production of PGC1-alpha, a protein that promotes mitochondrial biogenesis, the production of new, healthy mitochondria, and the activation of brown fat – a phenomenon once thought to occur only in newborns, but now known to occur in adults, especially after cold exposure.”

“Perhaps the most clear-cut examples of cryotherapy’s beneficial effects are observed in the brain, where levels of the hormone and neurotransmitter norepinephrine – responsible for vigilance, attention, focus, and positive mood – increase markedly when the body is exposed to extreme cold.”

“Measures such as refreshing and recirculating cabin air through specialized filters contribute to low transmission on airplanes. In this clip, Dr. Roger Seheult explains that well-ventilated spaces are a factor in dampening the spread of the SARS-CoV-2 virus.”

“SARS-CoV-2 infection during pregnancy can increase the risk for adverse pregnancy outcomes, leading some to question the safety of COVID-19 vaccines concerning fertility. Even though pregnancy was an exclusion criterion for participation, some women became pregnant during COVID-19 vaccine trials.”

“The most compelling human signal appears when the brain is under acute strain. In a randomized crossover study, a single dose of 0.35 grams per kilogram during 21 hours of sleep deprivation changed cerebral energy metabolites and preserved selected measures of cognitive performance.”

“A recent meta-analysis also found small benefits in selected cognitive domains, including memory and processing speed, with responses that may depend on age, diet, baseline stores, stress, dose, and the cognitive test used.”
