“This is a proposed metabolic advantage, not proof of slower brain aging. Small TBI trials found that sodium lactate lowered intracranial pressure more than mannitol in severe TBI and improved cognitive scores more than 3% sodium chloride in mild TBI.”

“A meta-analysis of seven randomized trials involving 182 participants found that high-intensity interval training improved flow-mediated dilation by 4.31%, compared with 2.15% after moderate-intensity continuous training, with a 2.26-percentage-point advantage between groups.”

“She uses that result to make consistency practical. Aerobic exercise does not need to be all-out every day, but sessions that raise heart rate and improve cardiorespiratory fitness provide a meaningful brain stimulus.”

“Standard metabolic screening still relies on validated laboratory measures such as A1c, fasting plasma glucose, or a two-hour glucose value after a standardized oral glucose tolerance test. Skin changes or unexpected glucose patterns can therefore be useful prompts for a clinical evaluation.”

“In 15 people with severe traumatic brain injury, sodium lactate infusion increased brain lactate, pyruvate, and glucose without raising intracranial pressure, and a randomized study in 60 patients with mild traumatic brain injury reported better cognitive recovery than hypertonic saline.”

“Mouse studies of feeding during infection also found different responses across bacterial and viral models, so a minimally processed dietary pattern, regular exercise, and normal hydration and nutrition during illness provide a more useful foundation than one universal food or fasting rule.”

“In an early randomized workplace study, healthy employees who completed an eight-week mindfulness program showed a greater rise in antibodies after influenza vaccination than a waitlist group.”

“A meta-analysis of 19 randomized trials involving 1,683 participants found modest average improvements, including about seven minutes less time to fall asleep and eight minutes more total sleep. Product quality can make dose selection difficult.”

“A small randomized trial in trained athletes found that 20 milligrams per day for two weeks increased total antioxidant capacity and glutathione peroxidase and reduced post-training DNA damage versus placebo; it did not test performance or long-term adaptation.”

“Whereas fasting turns off multiple pathways associated with aging, such as mTOR and IGF-1, eating for optimal fitness activates these important processes. The IGF-1 pathway, in particular, plays key roles in growth and is strongly associated with cancer.”
