Have you heard about fasted cardio? The raging trend for fat loss. The mere thought of waking up early, and dragging our butts to spin studio or gym without eating breakfast, is enough to make us want to stay in beds and eat poached eggs.

However, there are many people, including celebrities who swear by early morning fasted cardio. People believe fasted workouts are better for health and help burn more fat.

Let’s learn about fasted cardio in detail:

What Is Fasted Cardio?

Fasted cardio is performed when the digestive system is not processing food any longer. 

In simple words, fasted cardio exercise is done on an empty stomach without eating for six or more hours and without any pre-workout meal. The body enters in a fasting state after 6 hours.

People who follow intermittent fasting fix schedule to facilitate fasted training, because they restrict calories intake for a short period in a day.

 Warning: nutritionists do not recommend intermittent fasting at all.

It is proven scientifically that fasted cardio is better for fat loss compared to doing cardio after a pre-workout meal. But how? Let’s find out.

How Fasted Cardio Works?

The way fasted cardio benefits weight loss is very simple. 

When you work out on an empty stomach, the body source energy from fat rather than carbohydrates. This means you will burn more fat instead of glucose.

This has a scientific solution. When you ingest food, the digestive system breaks down complex food into glucose, which is then absorbed by cells. 

The mitochondria present in cells then convert the glucose into energy. This energy is used while doing workouts.

When your body does not get glucose, glycogen is used to get energy. But when the glycogen is not available body uses stored fat to get energy by breaking down into free fatty acids. 

When we fast overnight, there is no stored glucose, and the glycogen levels also deplete. Our body then uses stored fat to fuel the cardio sessions in a fasted state.

Isn’t it interesting? Fasted cardio alter the way our genes behave. It is the best way of burning fat and reducing the overall fat percentage.

Now let’s take a look at the science-based benefits of fasted cardio.

Science-Backed Fasted Cardio Benefits

Reduced Calorie Intake And more Fat burn

Fasted cardio helps reduce calorie intake. 

A study published in “the Journal of Nutrition and Metabolism.” showed that people who did not eat anything before 60 minutes of run consumed fewer calories later in the day compared to people who had breakfast before their cardio session. Fasted cardio also increases the fat oxidation rate, which leads to more negative energy balance compared to fed stomach cardio.

In one more study, American scientists found that resistance training in a fasted state metabolizes fat instead of carbohydrates. This is an indication that fasted cardio, when done correctly, is great for bodyweight management.

Improves Glucose Tolerance In A High-Fat Diet

Keto diet is a famous high fat diet, which is known to be very effective in weight loss. 

A study done on people aged 18-25 years for six weeks concluded that endurance training four days a week in a fasted state helps improve the body’s glucose tolerance and sensitivity to Matsuda insulin.

This means that people did not experience a spike in glucose levels in the blood compared to people who did fed cardio. Fasted cardio improves insulin sensitivity, which uptakes glucose from the blood.

Improves Fat Oxidation In Women

A study done on women revealed that doing endurance training for 60 minutes of empty stomach increased 24-hour fat oxidation. Meaning that women will continue burning fat the whole day even after the fasted cardio session ends.

The HIIT (high-intensity interval training) also works in the same way and burns more calories compared to endurance training. People who have heart or knee problems can perform fasted cardio and push their body in a fat-burning mode for the entire day.

Reduces Body Fat Percentage

Scientists researched the impact of cardio at the tie of Ramadan fasting in people. It was found that people who did fasted-aerobic exercise decreased their body fat percentage by 6.2%.

Fasted cardio is an excellent way of burning fat. It not only reduces hunger pangs and overall body fat percentage but also improves glucose intolerance for a high-fat diet.
