Physical activity on an empty stomach can not provide us essential vitamins for energy. Further, it causes energy loss and make us feel hungry and affect our physical abilities too. In cardiovascular exercises, carbohydrates are our main source of energy. As the reserves of the body are not always enough and that their use is slower, this fuel must come from food for good performance during the effort.
But what to eat?
The type of meal to be favored varies according to the time available before the physical activity. The longer the pre-workout meal, the more balanced and complete the meal. The meal must be rich in carbohydrates because they will be the main source of energy used.
At all times before training, you should avoid excess fat (frying, nuts, cheese, fatty meat, etc.) because they are long to digest and will reduce performance in training. You can also prefer some energy drink for Gym.
