07 May Are BCAAs really necessary tho?
There is one situation where BCAA supplementation makes sense and that’s during FASTED CARDIO
Most people think fasted exercise is simply “exercising on an empty stomach,” but there’s a bit more to it than that.
Fasted exercise is exercise done while in a “fasted” state, which has to do with insulin level in your blood…. not how empty or full your stomach feels.
Specifically, your body is in a fasted state when it is no longer absorbing nutrients from your last meal and insulin levels are at a low “baseline” level.
The hormones and signaling molecules related to fat burning work best in a fasted state.. hence why fasted cardio is a thing.
Furthermore, certain supplements that aid in fat loss like coffee, yohimibine and synephrine are maximally effective when taken before fasted exercise.
The bottom line is fasted training isn’t necessary for losing fat but it can speed up the process (and especially when combined with proper supplementation).
It does have one key drawback, however: accelerated muscle loss. That is, your body breaks down muscle tissue faster when training in a fasted state.
This is where BCAAs can help because the amino acid leucine suppresses muscle breakdown which means it can counteract the increase in muscle degradation that comes with fasted exercise!!!
