The Brain Consumes Lactose During Exercise
Scientists have discovered that lactose, a byproduct of intense muscular activities, can be used to fuel the brain with energy. When glucose, the natural fuel of the brain, is no longer present in sufficient quantities, the cell tissue can “switch” to alternative energy, to prevent any damage to the brain on account of the lack of energy.

Consequently, by consuming the lactose in the blood, the brain clears the way for glucose, the main powering substance in the body, to reach the mus...

This frees up the body's glucose to fuel the muscles in times of high energy demands on the body (Note: This meme must be wrong in using the term "lactose," because that is a sugar that comes from milk. "Lactate" is a byproduct of muscles consuming glucose that fuels the brain while the muscles take energy-precedence).

A Succinct Definition of Lactate
Lactate is a dynamic substrate with great potential as an energy
source in sports drinks. To date, however, the efficacy of adding
lactate to these drinks has been sparsely assessed [5,15,16]. Lactate
was once considered a metabolic waste but is now recognized as an
important energy substrate in the body. Lactate is the main
product of carbohydrate metabolism and can be used as a fuel in
working muscle cells shuttled to other tissues such as the heart where lactate is fuel [17], or to the liv...A byproduct of our muscles converting carbohydrates to energy, which appears to serve as a secondary energy source.

Lactate, Lactose, and Lactase
Lactate
Lactate is a negatively charged molecule formed from a compound called lactic acid. Some bacteria make lactate when they metabolize sugars. Humans also produce lactate as a byproduct of metabolism, though only under certain conditions. Specifically, says Dr. Gary Thibodeau in his book "Anatomy and Physiology," you make lactate when your cells process sugars for energy in the absence of oxygen, such as when you're engaging in a hard sprint or power efforts during exercise.
Lacta...Lactose and Lactase apparently have no relation to Lactate. Lactose is a sugar in milk, Lactase is an enzyme babies use to digest milk, and Lactate is a byproduct of our muscles expending energy, which is itself a source of energy.
