This week, we’re going to talk about the controversial realm of fasted cardio which I’m sure if you’ve been in the fitness space for a while, you’ve heard about. You’ll learn if there’s a use for it, what my biased opinion is about it (which may go against what is currently popular) and why I think that way.

“Based on the respiratory exchange ratio, fasting led to a greater utilization of lipids during rest and exercise. It was concluded that 1) a 36-h fast significantly altered substrate utilization at rest and throughout exercise to exhaustion, 2) glucose levels do not appear to be the single determinant of time to exhaustion in submaximal exercise, and 3) despite the apparent sparing of carbohydrate utilization with the 36-h fast, endurance performance was significantly decreased.”
Is any one of those single things more important than the others?
Lyle Macdonald has some thoughts about the whole thing too. Of course, he has a lot of thoughts about everything lol
