I didn’t use to, as I thought that i would burn fat. Since really learning about the body and nutrition, I know that all I’m doing is degrading muscle by not fuelling my body before a workout. Knowing that muscle is what will actually carry on burning calories long after my workout, I think it’s vital to eat before a workout. Have a read of this article, see what you think. I guess, it is all a matter of what your goals are, and if you have a lot of mass to lose, maybe this is a good way to start. I personally think that stressing your body into thinking its in starvation mode, will only be a negative for your health and goals.
Anyways food for thought
