“This surplus lactate can be "shuttled" to various tissues, including the muscles, heart, and brain, which use it as an energy source. Evidence suggests that lactate is the preferred fuel of the brain – pointing to its importance in maintaining cognitive function.”

“The benefits of HIIT include improvements in muscle tissue oxidative capacity, enhanced insulin response, improvements in heart function, and increased lactate – an important source of fuel for the heart, brain, and muscles.”

“Lactate may participate in glucose handling and training adaptation, but contraction-mediated GLUT4 movement also occurs through calcium-, energy-, and mechanical-signaling pathways. The clip therefore does not attribute insulin-independent glucose uptake solely to lactate.”

Dr. Rhonda Patrick and Brady Holmer discuss vigorous exercise, glucose transport, lactate signaling, and mitochondrial adaptation.

“Among its other signaling effects, lactate increases GLUT4 transporters in skeletal muscle, allowing for a greater amount of glucose uptake. This effect lasts for up to 48 hours, with the first 24 hours representing the most robust period of enhanced glucose control.”

“Activation of autophagy in human skeletal muscle is dependent on exercise intensity and AMPK activation - Shows vigorous aerobic exercise boosts mitophagy markers in humans. Lactate fuels the human brain during exercise - Demonstrates the brain can use lactate instead of glucose during exercise, challenging the belief that it relies solely on glucose.”

“Vigorous exercise also creates strong metabolic signals. Dr. Patrick describes lactate as both a fuel and a signaling molecule and explains how exercise intensity can increase catecholamine release and brain-derived neurotrophic factor.”

“Many women face challenges when breastfeeding, however, so family support and assistance from a lactation consultant can be helpful. In this clip, Dr. Rhonda Patrick discusses how breastfeeding benefits mothers and describes some of the challenges women who breastfeed face.”

Alcohol, in particular, can have negative effects on a breastfed infant, including altered sleep patterns, decreased milk intake, and impaired motor development (https://link.springer.com/article/10.1007/s00216-010-3681-0), among others.

“Dr. Patrick distinguishes human associations between exercise lactate and circulating BDNF or norepinephrine from animal evidence for direct brain BDNF effects. She also discusses serotonin and norepinephrine signaling, focus, and impulse control.”
