Fasting training: advantages and disadvantages

Fasted training is a training method in which you do not consume any food or drink before training. There are different opinions and approaches to fasted training. This article discusses the advantages and disadvantages of this training method.

Benefits of fasted training

1.Fat loss:When training on an empty stomach, the body increasingly relies on fat reserves as an energy source because the glycogen stores in the liver are emptied during fasting. This can promote fat loss and contribute to weight loss.
2.Insulin sensitivity:Fasting training can improve insulin sensitivity. Insulin is a hormone responsible for regulating blood sugar levels. Training on an empty stomach allows the body to respond more efficiently to insulin and better regulate blood sugar levels.
3.Hormonal adjustments:When training on an empty stomach, hormonal changes occur that can have a positive effect on the body. For example, the level of growth hormone (GH), which is important for muscle growth and fat burning, increases.
4.Efficiency:Fasted training can shorten training time because you don't have to spend time eating before training. This can be particularly beneficial for people with busy schedules.

Disadvantages of fasting training

1.Energy depletion:When training on an empty stomach, energy reserves can be quickly depleted because the body has no direct source of energy. This can have a negative impact on exercise performance and lead to premature fatigue.
2.Muscle loss:There is a risk of muscle loss when training on an empty stomach. Without sufficient nutrients, the body can use muscle protein as an energy source, which can lead to loss of muscle mass.
3.Hypoglycemia:Low blood sugar concentration (hypoglycemia) can occur during fasting exercise. Symptoms such as dizziness, poor concentration, fatigue and shaky hands can affect exercise performance.

Frequently asked questions

1. Is fasting training suitable for everyone?
Fasted training is not suitable for everyone. People with certain health conditions, such as type 2 diabetes or low blood sugar, should definitely speak to a doctor before fasting exercise. Pregnant women or those with eating disorders should also exercise caution.

2. What type of training is best for fasted training?
Fasted training is best suited for light to moderate intensity aerobic exercise such as running, cycling or swimming. Intense and prolonged strength-based activities may be more difficult because energy reserves are limited.

3. How long should you fast before starting exercise?
The ideal length of fasting before exercise varies from person to person. Some people prefer a short fast of 8-12 hours, while others consider longer fasts of up to 16-18 hours. It is important to listen to your own body and individual needs.

4. Are there alternatives to fasting training?
Yes, there are alternative training methods that can also offer benefits. For example, training after a light meal or training after taking a light snack that provides enough energy but is not too heavy on the stomach.

Conclusion

Fasted training has its advantages and disadvantages. It can help with fat loss, improve insulin sensitivity, and cause hormonal adjustments in the body. But there is also the risk of energy depletion, muscle loss and hypoglycemia. Everyone should decide for themselves whether fasting training suits their own goals and needs. It is advisable to seek medical advice before performing fasting training to consider any possible risks or limitations.
