“He observed that in most cases, metabolic rates were a reflection of body mass and closely tracked estimations from predictive equations. In this clip, Dr. Ray Cronise emphasizes the importance of diet to improve healthspan rather than employing tricks to boost metabolic rate.”

“Dr. Rhonda Patrick describes a food routine built around adequate protein, vegetables, fruit, and fiber. In this clip from Q&A #84, she shares a personal protein minimum of 1.2 grams per kilogram of body weight daily and a usual intake closer to 1.3 to 1.4 grams.”

“In this FoundMyFitness interview clip, Dr. Peter Attia explains that early detection can reduce the burden of disease available to mutate and evade treatment, but screening carries financial, procedural, and false-positive harms.”

“Longer-term nutrient status offers another perspective: in a randomized trial of adults with overweight or obesity, 15 grams of psyllium daily for three months did not significantly alter serum micronutrient concentrations relative to control.”

“In a six-month trial of adults with peripheral artery disease, a flavanol-rich cocoa beverage improved six-minute walking distance measured 2.5 hours after dosing. In older adults with mild cognitive impairment, higher-flavanol cocoa improved selected verbal-fluency and executive-function tests over eight weeks.”

“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.”

“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.”
