“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.”

“Caloric restriction mimetics – compounds that “trick” cells into inducing autophagy even in the setting of sufficient nutrient levels – include resveratrol, which is found in red wine, and spermidine, which is found in cheese.”

“Brady Holmer turns the protocol into a weekly framework: one interval session, one longer easy session, additional base-pace activity, active recovery, and at least two resistance sessions. Dr. Patrick emphasizes the progressive build.”

“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.”

“The oversimplified view that high-density lipoprotein (HDL) cholesterol is good, and low-density lipoprotein (LDL) cholesterol is bad has led to misunderstandings of the relationship between cholesterol and cardiovascular disease risk.”

“Preliminary findings from a study analyzing UK Biobank data with over 25,000 participants suggest that even 3-4 minutes of VILPA daily could reduce all-cause mortality risk by 25-30%.”

“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.”

“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.”
