“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“The body has elegant mechanisms that allow it to utilize non-carbohydrate substrates to generate glucose. Gluconeogenesis is a metabolic pathway in which the liver produces glucose from non-carbohydrate substrates including glucogenic amino acids (from protein) and glycerol (from lipids).”

“Dr. Patrick then prioritizes lower-glycemic-load, less-refined foods and adequate fiber. Early time-restricted eating can help some people reduce calories and may influence selected metabolic markers, but it is not required and must still preserve protein and diet quality.”

“Translating sleep insights into practical steps These findings highlight the possibility of using heat therapy or vigorous exercise to influence slow-wave sleep, drawing on the interplay between body temperature regulation, immunity, physical activity, and hormones.”

“This effect, sometimes called the 'afterburn effect,' does have some scientific basis, according to recent podcast guest Dr. Martin Gibala. In scientific terms, it's known as EPOC or Excess Post-Exercise Oxygen Consumption.”

“A systematic review found no overall improvement in mood after cold-water immersion, while a small randomized trial found that repeated whole-body cryotherapy improved depression scores when added to standard pharmacological treatment.”

“A small magnetic-resonance spectroscopy study also found that 20 grams per day for four weeks increased brain creatine by an average of about 8.7 percent, showing that brain uptake is possible but variable.”

“High energy demand is a promising research setting. In a randomized crossover study of 15 healthy adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed cerebral energy measures and improved selected cognitive outcomes.”

“In a randomized crossover study of 15 adults, a single weight-based dose changed cerebral energy metabolites and reduced deterioration on some cognitive tasks during about 21 hours without sleep. Dr. Patrick uses 10 grams daily and sometimes takes more during travel or sleep loss.”

“A single 0.35-gram-per-kilogram dose of creatine monohydrate, equal to 24.5 grams for a 70-kilogram adult, reduced fatigue and improved word memory and processing speed on selected tasks versus placebo. It also changed brain-energy measures.”
