Running is a widely loved form of exercise, and many enthusiasts find that doing it first thing in the morning, sometimes without eating, brings a slew of benefits. The idea of working out on an empty stomach can feel intimidating, but this practice, often referred to as “fasted cardio,” can be good for your health.
Here are some reasons why it might be beneficial for your body:-
1. Increases Fat Burning
One of the best-known perks of running on an empty stomach is that it can help you burn fat more effectively. When you run without eating first, your glycogen stores—your body’s carbohydrate reserves—are low. As a result, your body turns to stored fat for energy, which can promote fat loss over time. Studies suggest that fasted workouts can enhance fat burning compared to running after meals.
2. Boosts Insulin Sensitivity
Running without food can enhance how well your body responds to insulin. Insulin sensitivity is all about how effectively your body uses insulin to take in glucose from your blood. When you’re in a fasted state, your insulin levels drop, which can help your body become better at managing insulin. Over time, better insulin sensitivity can lower the chances of developing type 2 diabetes and improve overall metabolic health.
3. Supports Hormone Balance
Exercising on an empty stomach can positively influence hormone levels. In particular, it can boost growth hormone production, which plays a key role in burning fat and building muscle. During workouts when you haven’t eaten, levels of growth hormone can rise, aiding in tissue repair and fat breakdown. Plus, cortisol, a hormone related to stress, can be better managed when you’re fasted.
4. Enhances Mental Focus
Running without having eaten can prompt your body to use fat for energy, which increases the production of ketones. These are substances created when fats are broken down and are known to support brain function. Shifting from carbs to fats can enhance focus and mental alertness during your workout. Many people report feeling sharper and more concentrated after a session of fasted cardio.
5. Boosts Endurance
Prepping your body to run on an empty stomach can lead to better endurance over time. Regularly running without eating helps your body get better at using fat for energy. This is important because fat provides a longer-lasting energy source for extended workouts. Runners who practice fasted cardio may notice improved stamina during longer races or endurance challenges.
6. Speeds Up Weight Loss
Doing brisk runs while fasted can help speed up the weight loss process. Since your body relies on fat for energy during these runs, you’re likely to burn stored fat more quickly, making weight loss more efficient. Over time, running on an empty stomach can assist in shedding stubborn weight, especially when paired with a balanced diet and regular exercise.
7. Improves Mitochondrial Function
Running without eating may enhance how well your mitochondria—the energy centers in your cells—work. Exercising in a fasted state helps your body adapt to using fat for energy, which can improve mitochondrial health. This boosts your body’s ability to create energy effectively, supporting better performance in physical activities.
8. Promotes Better Fat Use Later
When you train your body to rely on fat for energy during fasted runs, it can carry that ability into other activities later in the day. This means your body will keep burning fat at an increased rate, both during your run and for hours afterward. As a result, you might enjoy more calories burned even when you’re not exercising.
9. Encourages a Steady Morning Routine
Running on an empty stomach in the morning can help you build a consistent routine. Kicking off your day with exercise can lift your mood, boost your energy, and create a positive atmosphere for the rest of the day. Additionally, morning workouts can help set your body’s internal clock, making it easier to rise early and excel in various aspects of life, such as work and social activities.
Though running on an empty stomach might not suit everyone, it can serve as a healthy option for improving fat burning, endurance, and overall fitness for those who feel comfortable with it. From better fat burning and improved insulin sensitivity to enhanced mental focus and stronger mitochondrial function, there are plenty of reasons to consider morning runs on an empty stomach. Just remember to listen to your body and avoid pushing yourself too hard, especially if you’re new to this practice. Like any exercise routine, being consistent and balanced is essential to enjoying the full advantages.
