Benefits of fasted cardio

When you do cardio in a fasted state, your body is forced to use stored fat for energy rather than the food you’ve recently eaten. This can lead to increased fat burning and weight loss over time.

Fasted cardio can also help improve your insulin sensitivity, which is the ability of your body to use insulin effectively. This is important because insulin resistance is a major factor in conditions like type 2 diabetes and obesity.

Lastly, fasted cardio can help increase your levels of human growth hormone (HGH). HGH is a hormone that helps with tissue repair, muscle growth, and fat burning.

Risks of fasted cardio

There are a few risks associated with fasted cardio that you should be aware of before trying it. First, if you have any medical conditions that could be exacerbated by exercise, fasting, or low blood sugar, fasted cardio is probably not for you. Second, if you are not used to exercising in a fasted state, you may feel lightheaded or dizzy during your workout. Finally, if you overdo it, you could end up burning muscle instead of fat. So, as with anything, moderation is key when it comes to fasted cardio.

When to do fasted cardio

The best time to do Fasted cardio is in the morning before breakfast. This is because your body will have been fasting overnight and will be more likely to burn fat for energy. Fasted cardio can also be done later in the day, but it may be more difficult to do if you haven’t eaten anything since breakfast.


Overall, fasted cardio can be a great way to improve your cardiovascular health and lose weight. However, it is important to understand the risks and benefits before you begin. If you have any medical conditions, be sure to speak with your doctor before starting fasted cardio. When done correctly, fasted cardio can be a safe and effective way to improve your health.
