Evidence suggests that there are numerous potential benefits of combining exercise with fasting. Working out while fasting has seen a surge in popularity due to the fact that it can help accelerate fat burning and weight loss. However, the practice is not without risk, so it’s important to inform yourself on the pros and cons before you decide whether or not to try it.

This guide aims to provide an overview of the latest research on working out while fasting, examining both plausible benefits and potential risks associated with engaging in fasting workouts. We’ll discuss:

  • what sorts of workouts are safe for people engaging in a fasting-exercise regimen, as well as which types should be avoided.
  • basic tips to maximize performance during these workouts.
  • guidelines for avoiding potential injury or discomforts while training fasted.

Benefits of Working Out While Fasting

Working out while fasting can have some great benefits for your body. Studies show that working out while fasting can help with fat burning and muscle growth. It can also help to increase the body’s ability to utilize different fuel sources. It can even help to regulate hormones and improve overall performance.

In this article, we’ll explore the benefits of working out while fasting in more detail:

Improved Mental Focus

Working out while fasting can be a beneficial practice for many people. Not only does it help control weight and improve physical appearance, but it also has many potential mental benefits as well. One of the most often noted advantages is improved mental focus.

When you fast before exercising, your body needs to rely on its internal energy stores to fuel the workout, meaning that you can reach a much higher level of concentration and mental alertness than if you were working out with full energy reserves. This can help make your time in the gym more enjoyable, as well as helping you stay focused on your goals and stick to an exercise plan.

Fasting also helps reduce stress levels, which can take some of the pressure off when trying to build up your strength and endurance in the gym. When cortisol levels are low (from reduced stress), the body is able to exercise more efficiently; this means:

  • less fatigue during workouts
  • faster recovery times after workouts
  • improved gains from physical activity overall

Furthermore, because less energy is needed for bodily maintenance functions such as digestion during a fasted state of lower cortisol levels, more energy is available for reaching your fitness goals faster!

Increased Fat Loss

Engaging in physical activity while fasting may be an effective way to support the body’s natural ability to burn fat. Fasted exercise has been shown to burn up to 20–30% more fat than working out after eating a meal. This is likely because it takes the body some time to digest a meal, so the body must yearn for fuel while fasted. In most cases, this means that it will be inclined to burn fat as opposed to carbohydrates and sugars which can lead to increased fat burning capabilities if done consistently.

Additionally, fasted aerobic exercise has been found to improve insulin sensitivity when done over several weeks – meaning that your body is capable of using its insulin more efficiently, leading again to further fat loss over time.

Fasted resistance training can also cause an increase in metabolic rate and promote further muscle growth when combined with resistance training such as weight lifting and high-intensity interval training (HIIT). By engaging in consistent exercise while fasted your body will become accustomed burning more fats for energy eventually resulting in increased weight loss.

While none of these benefits are immediate, by consistently performing fasted exercising you will be able create positive metabolic changes over time leading you closer towards your goals!

Improved Insulin Sensitivity

Working out while fasting has been studied extensively and may result in improved insulin sensitivity, meaning your cells will become better at absorbing glucose, which helps to improve metabolism. Studies have shown that engaging in endurance activities like running and cycling while fasting can increase your insulin sensitivity by up to 75%. This is beneficial for those with diabetes or metabolic syndrome since improved insulin sensitivity can help lower blood sugar levels.

Additionally, studies have found that working out while fasting may increase the production of enzymes in the body that break down fat cells, resulting in increased fat burning.

Drawbacks of Working Out While Fasting

Working out while fasting has become increasingly popular over the past few years, with many adherents claiming it has a wide range of health benefits. However, there are some potential drawbacks to consider before relying solely on this approach.

In this article, we’ll look at some of the potential downsides to working out while fasting and provide insight into how to make it work for you.

Low Energy Levels

Working out while fasting can lead to low energy levels, as there is no source of glucose available for the body to use as fuel. This can result in fatigue, dizziness and impaired performance during your workout. It is important to consume enough energy for physical activity, as energy levels affect your overall performance. Without sufficient energy, you may be unable to perform vigorous exercise and reach exhaustion more quickly.

  • Before fasting for extended periods, make sure you have adequate nutrient stores in the body so that your muscles don’t suffer from depletion.
  • Additionally, drinking plenty of water before, during and after physical activity to help promote better hydration levels and reduce dehydration risk.
  • Since working out while fasting depletes your body’s glycogen stores faster than usual, try eating a small snack 30 minutes before exercising.
  • Eating a healthy meal or snack prior to exercise may reduce feelings of fatigue and increase endurance during physical activity. Not only will this provide you with the necessary energy boost but it will also help improve muscle building benefits post-workout.


Working out while fasting can be associated with an increased risk of dehydration. When you exercise, your body temperature rises, which can cause you to sweat more than usual. Your body naturally uses water to lower your temperature and for metabolic processes related to energy production. Sweating can cause you to lose water faster, taking away from what is needed for your muscles to work properly.

Another issue is that when fasting, your body’s normal counter-regulatory hormones that stimulate thirst may be suppressed, resulting in lack of thirst sensation, making it difficult to drink enough fluids during the workout session. Dehydration can lead to an array of problems such as cramps and dizziness. Thus, it is important that when exercising during fasting hours adequate hydration should always be a priority.

  • This includes not only drinking plenty of water before and during the exercises but also adding in electrolytes as needed (such as sodium and potassium).

Increased Risk of Injury

Working out while fasting may put people at greater risk of injury. During fasting, the body’s energy levels tend to be lower than normal, so they can’t sustain the same intensity of exercise as they normally would. As a result, it may be harder to focus and maintain proper form during a workout. In addition, people may not have access to fast-acting sources of energy to replenish their bodies during exercise, which can increase fatigue and reduce performance.

Fasting can also impair muscle recovery after an intense workout session. As muscles are damaged and torn during a workout, the body needs the calories from food in order to repair those tissues. Without fuel from food before or after working out, it’s more difficult for those tissues to properly regenerate themselves. This can lead to long-term damage or even acute injuries that can prevent individuals from exercising for weeks or months at a time.

In addition, when working out while fasting people are also at risk of:

  • Becoming dehydrated more easily than usual due to reduced levels of circulating water in the body as well as inhibited water absorption rates that accompany longer periods without food intake.
  • Decreased performance and accuracy during high-intensity exercises.
  • Increased risk of muscle cramps and headaches while exercising which can potentially impact overall health outcomes down the line if not monitored properly.


In conclusion, it is safe to say working out while fasting can be beneficial in terms of weight loss and improved health. However, the type and intensity of exercise should be carefully considered when performing any physical activity in a fasted state. It is important to note that there is no one-size-fits-all approach and that individual needs may vary depending on age, health status, and other lifestyle factors.

Consult with a licensed healthcare practitioner or nutritionist before making any major changes to your diet or exercise regimen.
