Should You Exercise on an Empty Stomach? Pros, Cons and What Science Says

Introduction

Exercising on an empty stomach is a controversial topic in the fitness world. Some people swear by it, claiming that it helps them get the most out of their workouts, while others are skeptical of its purported benefits and potential risks. So what is exercising on an empty stomach and should you give it a try? In this article, we’ll explore the pros and cons of exercising on an empty stomach and what science says about this practice.

What is Exercising on an Empty Stomach?

Exercising on an empty stomach is exactly what it sounds like: working out without eating anything beforehand. This doesn’t mean you can’t have anything to drink before your workout; in fact, some experts recommend having a glass of water or a cup of coffee to stay hydrated. But the idea is to avoid eating any food before your workout.

Pros and Cons of Exercising on an Empty Stomach

The potential benefits and risks of exercising on an empty stomach depend largely on the type of exercise you’re doing and your individual goals. Let’s take a closer look at the pros and cons of exercising on an empty stomach.

Improved Performance

One of the main benefits of exercising on an empty stomach is improved performance. Studies have shown that working out on an empty stomach can help improve endurance and power output, as well as reduce fatigue during exercise. This may be due to the release of hormones such as adrenaline and cortisol, which can help increase energy levels and alertness.

Increased Fat Loss

Another potential benefit of exercising on an empty stomach is increased fat loss. When you don’t eat before a workout, your body is forced to use stored fat for energy instead of recently consumed calories. This can lead to greater fat burning during exercise and more overall weight loss.

Reduced Risk of Injury

Working out on an empty stomach can also reduce the risk of injury. Eating before exercise can cause GI distress, which can lead to cramping and dehydration. By not eating before a workout, you can help prevent these issues and reduce your risk of injury.

Potential Risks

While there are some potential benefits to exercising on an empty stomach, there are also some risks to consider. Working out on an empty stomach can lead to lightheadedness and dizziness, as well as decreased energy levels and performance. It can also put additional strain on your digestive system, which can lead to GI distress and other issues.

What Science Says About Exercising on an Empty Stomach

Although there are anecdotal reports of the benefits of exercising on an empty stomach, scientific research on the topic is still scarce. A few studies have been conducted to examine the effects of exercising on an empty stomach, but the results are mixed.

Overview of Studies

One study examined the effects of exercising on an empty stomach in nine healthy men. The researchers found that working out on an empty stomach led to better performance and increased fat burning. However, they also found that the participants felt more fatigued after the workout than when they ate before the workout.

Another study looked at the effects of exercising on an empty stomach in eight women. The researchers found that working out on an empty stomach led to improved endurance and increased fat burning. However, they also found that the participants experienced increased levels of perceived exertion, meaning they felt like they were working harder than when they had eaten before the workout.

Summary of Findings

Overall, the findings from these studies suggest that working out on an empty stomach can lead to improved performance, increased fat burning, and reduced risk of injury. However, it may also lead to increased levels of perceived exertion, increased fatigue, and lightheadedness.

How to Maximize Your Workout by Exercising on an Empty Stomach

Hydration and Nutrition Before Exercise

When it comes to timing your meals, it’s important to find a balance between getting enough fuel and not eating too close to your workout. Generally speaking, it’s best to eat at least two hours before exercise, but everyone is different and you may need to experiment to find out what works best for you.
