The idea behind it is that exercising on an empty stomach might stimulate fat oxidation – the breakdown of fat into energy – and, in turn, improve endurance by teaching the body to rely on fat as a primary fuel source.

In this post, we’ll dive into what current research says about fasted training and endurance, as well as some potential risks associated with this approach.
