When it comes to how to lose fat as fast as possible, then it’s often wise to include some form of cardio for fat loss in your routine to speed up the process. But, to lose fat fast, many suggest performing your cardio on an empty stomach – or in other words “fasted cardio” often first thing in the morning. But what exactly are the fasted cardio benefits? Does fasted cardio work in terms of fat loss and weight loss? What fasted cardio results can you expect to see after implementing it? And how do you do fasted cardio in the first place? Well, in this video I’ll answer all those questions.

The basic theory behind fasted cardio being superior for fat loss is the fact that research has shown that when exercising in a fasted state, your body preferentially burns more fat for energy since your insulin and glycogen levels are low during this period. Whereas when you eat before you exercise, your body now tends to preferentially use more carbs and less fat for energy when compared to if you were fasted. And this is mainly what led people to believe that performing your cardio in a fasted state would speed up fat loss to an even greater degree. However, although it’s true that you burn more fat during a fasted cardio session, it’s vital that you take into consideration the post exercise period and what happens to your body after the session. Because research has shown that although you may have preferentially burned more fat during the fasted cardio session, your body eventually compensates for this by burning more carbohydrates for the rest of the day. So by the end of it, you’ve essentially burned the same amount of fat as you would have had you eaten before your cardio.

But with that being said, there are some fasted cardio benefits that explain why so many people use it in their routines to lose fat. First off, it often indirectly reduces your calorie intake and makes it easier for you to eat at a calorie deficit since your meals are pushed closer together throughout the today. Secondly, getting your fasted cardio workout done first thing in the morning as opposed to waiting later in the day when you’ll be more likely to skip it often helps with consistency and adherence.

Now as for how to do a fasted cardio workout, you’ll want to mainly stick to low to moderate intensity cardio sessions lasting less than an hour long. HIIT fasted cardio should be used sparingly as it requires a lot more time to recover from and depletes your glycogen to a greater extent which can be detrimental especially if you’re going to be lifting weights later on in the day.

But all in all, although fasted cardio doesn’t have any magical fat loss effect in of itself, it may be useful for its indirect benefits.
