Fasting training is what you want to increase your body's expense when it is empty of glycogen and can only use fat for energy. But it is not suitable for everyone.
In the attempt to lose weight we are able to try everything, and one of the most common recommendations we find on the Internet is to practice fasting cardio . It is a technique used by many to optimize the loss of body fat and enhance it.
The logic behind this method is as follows: if you do fasting cardiovascular exercise you are forcing the body to use body fat as an energy substrate since glycogen stores are low and insulin levels are also due to fasting. That makes you start burning fat from minute 1 and the whole process is more efficient.
Those who follow this trend believe that fasting cardio is a fundamental step in the loss of body fat, but what many do not take into account is that it can be harmful to the body.
The reason that fasting cardio helps you lose fat is because when you wake up your blood glucose and insulin levels are low. Since the body gives fat priority over any other source of energy, eating any food will make your body use it as an energy source rather than fat deposits.
Now, when you do cardio without having eaten, consider the following:
If you have insulin resistance or are hypertensive, it can cause severe health problems.
- Fasting cardio is only before exercising. Be sure to eat once you have finished, preferably a low carbohydrate complex carbohydrate and protein .
Do not wait more than 15 minutes from the moment you wake up to do the cardio routine.
Neither do it with a high intensity , since your body could respond negatively to the dynamics. Preferably, it lasts 40 minutes , no more, and you can have a conversation while you exercise.
Cardio is not equal to the work of forces. You should never train with fasting weights because the body needs a high amount of energy. To train in this way you must eat protein and carbohydrates first.
