The Pros

1) Increased Fat Burning: When you do cardio on an empty stomach, your body is forced to burn more stored fat for energy. This means that you will be able to lose weight and burn fat faster than if you did cardio after eating a meal.

2) Improved Insulin Sensitivity: This cardio can also help to improve insulin sensitivity, which is important for overall health and preventing diabetes.

3) Greater Calorie Burn: Studies have shown that this cardio can result in a greater calorie burn than non-fasted cardio. This means that you could potentially see better results from your workouts in less time.

The Cons

1) Increased Risk of Injury: When you do cardio on an empty stomach, your body is not as well-fueled as it would be if you had eaten a meal first. This can increase your risk of injury since your muscles will be weaker and less able to support your body weight.

2) Lower Intensity: Because your body is not getting any energy from food, the intensity of your workouts will likely be lower than if you were eating something before working out. This means that you may not see as great of results from fasted cardio.

3) Dizziness and Lightheadedness: This cardio can sometimes cause feelings of dizziness or lightheadedness, especially during the first few weeks of starting this type of exercise regime. If you experience these symptoms, be sure to stop your workout and drink some water.

4) Difficulty Completing Long Sessions: Another downside to cardio is that it can be difficult to complete long sessions without feeling tired or lightheaded. This can make it difficult to stick with a routine.


So, is this cardio right for you? That depends on your individual goals and preferences. If you are looking to lose weight quickly or improve your insulin sensitivity, then this type of cardio may be a good option for you. However, if you are looking for a high-intensity workout that will burn more calories, then you may be better off doing non-fasted cardio. Ultimately, it is up to you to decide what is best for your body and your goals.
