For the longest time now, people have debated extensively over how and why doing cardio exercises in a fasted state can work in a highly effective manner. With all theories aside, let’s have a look at the human body’s capability for dealing with exercise while having low-blood sugar levels.
The truth is that when you don’t consume any foods for longer periods, your glucose levels drop and your body is set into a catabolic state. This means that the body starts using muscle for energy. You can imagine if you exercise in this state, you are likely to put your body at the risk of losing muscle even further.
As such, it is best advised that you refrain from exercising at all during a fasted state as it is likely to leave a detrimental effect on your body’s muscle-gaining capabilities.
