I’ve already touched on the topic of fasted cardio here, but a recent publication by some of my favorite names in the industry (ie Alan Aragon) has shed some more light on the pro/anti fasted debate.
As I stated before, the entire idea around fasted cardio is that you’ll burn more fat. Since your body has no circulating glucose to utilize, it will instead pull from stored glucose preferentially. This translates to burning straight fat. This has gone under fire from a lot of critics because a) the body doesn’t work so simply and b) long term vs. short term calorie burn. This paper focused on comparing females in a caloric deficit.
The paper, published in November of this year, took two groups of women. The first group trained fasted, the second did not. Both groups were in a caloric deficit, both groups did an hour of steady-state cardio 3 days a week.
And both groups lost the same amount of fat and weight.
This short addendum to my fasted cardio article from previously shows that fasted cardio has no added benefit over non-fasted cardio.
