Practicing physical activity on an empty stomach has been an increasingly common activity and the reason is simple: optimization of fat burning and weight loss. Despite being a topic that divides opinions, this habit has gained space in the lives of those who seek health and high performance in their routine.
The benefits of practicing intermittent fasting are many. In addition to helping to lose weight quickly and healthily, it is able to stimulate brain nutrition, increase the number of mitochondria in neurons, and improve learning and memory.
Adherence to fasting in everyday life also has a direct influence on reducing oxidative stress and insulin resistance, promoting a better quality of life, preventing diseases such as cancer and diabetes, in addition to keeping our cells more resilient, and delaying aging.
Benefits of training fasted
The practice of physical activity is already an action capable of strengthening and repairing different functions of our body, keeping bones, joints, and muscles healthy, improving blood circulation, and promoting physical and mental well-being, among other advantages.
However, when daily training is combined with fasting, your body works optimally. It works like this: after eating, the body is busy digesting the food and ends up leaving the calorie-burning generated by exercise aside.
Thus, instead of burning fat that already exists in adipose tissue, the body will consume the newly ingested carbohydrates as a source of energy. But when you exercise after a long period of food restriction, the body doesn’t have the glucose available in the blood to serve as a source of energy.
Soon the body starts to use fat as a quick source to obtain the necessary energy at that moment of movement, that is, it starts to burn fat as fuel, stimulating weight loss.
How does intermittent fasting speed up weight loss?
The practice also increases the levels of adrenaline and noradrenaline, hormones that help the body to release more stored energy (body fat), causing more favorable changes in our body, and offering health benefits also in the long term.
In addition, training in a fasted state helps increase insulin sensitivity, which enhances the body’s efficiency in metabolizing food, and increases the production of the GH hormone, the growth hormone, important in lipolysis and lean mass gain.
Types of activities to do on an empty stomach
The most suitable activities to perform while fasting are endurance: running, cycling, walking, swimming, Brazilian Jiu-Jitsu etc. That’s because these exercises primarily use fat as an energy source.
