Unlike a car, your body can receive some benefits from working out on empty. A recent study that was published in The Journal of Physiology shows that an intense working out before consuming breakfast increases your body’s ability to metabolize fats and creates increased levels of a muscle protein that plays a role in regulation of insulin sensitivity.
What that means is, since your body does not have carbohydrates readily available to use for energy after a big meal, it has to burn already available fats for a fuel sources. However, this could potentially cause your performance to suffer somewhat if you don’t have adequate fuel to burn. This is why many athletes consume large amounts of carbohydrates as fuel.
If you are trying to lose weight, this may be a helpful tool for you to use when you are working out. The next time you wake up to go to your Rockbody boot camp, you may want to try avoiding eating until after your workout. Seeing how refueling post workout is optimal for recovery, you want your body to be able to recover at it’s highest level while still reaping the benefits of teaching it how to efficiently use fat stores in the muscles.
