It’s Just Not A Muscle Thing

One gap in these studies was what happens during normal non-exercise activity and resting. The current study fills that gap and supports the idea that when lactate levels in the blood remain high, it is a signal that something is disrupting the lactate shuttle cycle, not that lactate itself is harming the body.

"It's really informative about various medical conditions," Dr Brooks says. "I think what's significant about the current result is that it's just not a muscle thing. It starts with dietary carbohydrate. This was a missing piece in the puzzle."
