The benefits and drawbacks of exercising on an empty stomach.

1. Benefits of exercising on an empty stomach

Many studies have found that exercising on an empty stomach is beneficial. If you want to lose weight, exercising in the morning has been proven to be the most effective way to work out. This is related to the use of glycogen, a substance in the body that stores carbohydrates for the body to use as energy.

When we wake up, glycogen stores in our bodies are depleted. Therefore, when we exercise in the morning, instead of using carbohydrates for energy, the body starts using glycogen, which helps us lose weight.

Therefore, exercising on an empty stomach can help:

- Lose weight fasterIf you're aiming to lose weight and reduce belly fat, experts recommend exercising in the morning on an empty stomach.

Exercising on an empty stomach will burn even more fat. A study conducted by Cambridge University Press showed that people who skipped breakfast burned more body fat than those who did eat breakfast.

ButImprove insulin sensitivity:Numerous studies have found that exercising while fasting is a great way to improve insulin sensitivity.

For people in good physical condition and without any health problems, exercising on an empty stomach is fine, but for those with low blood sugar, exercising on an empty stomach can cause dizziness, lightheadedness, and nausea.

In short, exercising on an empty stomach helps ensure that carbs, protein, and fat go to the right places and are stored minimally as body fat. Exercising on an empty stomach has been shown to be particularly good for fat loss and even better at burning fat.

Furthermore, waking up and running out of the house to exercise or go to the gym is much simpler than exercising after having breakfast. You might also feel lighter during your workout.

2. Disadvantages of exercising on an empty stomach

Some disadvantages of exercising on an empty stomach include:Feeling uncomfortable and lacking energy if exercising for too long (more than an hour).Lower maximum oxygen uptake (maximum VO2) during exercise means reduced endurance.This can lead to muscle loss.It's not effective if you choose high-intensity training, for example, HIIT...Exercising on an empty stomach requires experience.It can cause hypoglycemia and other health problems such as dizziness, weakness, and even fainting during exercise.

In summary, exercising on an empty stomach is especially recommended for those on a weight-loss diet, when you are particularly focused on reducing fat.

3. Tips for safely exercising in the morning on an empty stomach.

Here are some tips to help you exercise safely:

ButDrink water upon waking up:Drinking 100-200ml of water immediately upon waking (slowly) will help the body start up quickly and boost metabolism.

- Start with lower intensity exercises.It's best to exercise at a lower intensity when you're hungry, then gradually increase the intensity. Yoga is a low-energy activity that will help you prepare for this.

ButListen to your body.If you experience symptoms such as dizziness, lightheadedness, nausea, or fatigue, stop exercising. Do not overexert yourself if you experience any of these symptoms, as they indicate that the exercise is negatively affecting your body.

- Remember to replenish energy after exercise.During exercise, muscles become very sensitive to available nutrients, and this sensitivity only lasts for a limited time. That's why the timing of nutrient supplementation after exercise is so important.

In the 30-45 minutes following exercise, you should try to replenish carbohydrates and protein. During this crucial period, muscle cells are more sensitive to the effects of insulin, a hormone that helps transport amino acids (from protein) into the cells.

Insulin also works to propel carbohydrates into cells, where they are stored as glycogen. These carbohydrate reserves can then be used to provide energy for muscles during subsequent activity.

Note that whether you should eat before or after exercise depends on the type of workout you're doing. For gentler, less impactful exercises, eating beforehand may not be necessary, such as walking or yoga.

If your exercise routine requires a lot of strength or energy, such as running or swimming, you should eat about an hour before exercising.
