Katherine: My friends swear by fasted cardio and tell me you get better results. Is this true?
Megan: Many people think that fasted cardio is essentially doing cardio on an empty stomach. When you wake up and do cardio your body is still digesting food from your last meal from yesterday. The body enters a fasted state 3 to 6 hours after eating depending on what was eaten. After you eat, insulin levels are elevated but when fasted they are at baseline and this is when fat is burned. The easiest way to train fasted is first thing in the morning. There are fat burning benefits but for some they don’t have the energy to perform a quality workout. Therefore, fasted cardio isn’t the best if you tucker out early. Your friends have a good point, but everyone’s body is different.
