Some people get used to doing the training on an empty stomach. This in fact runs counter to the purpose of losing weight.
During energy metabolism, consuming fat requires the assistance of an appropriate amount of glucose. Glucose is the major source of energy in the early stage of exercise and serves also as an indispensable fuel for strenuous exercise. Fat is liable to be insufficiently burned due to a lack of energy (glucose) intake. As a result, the energy source for aerobic exercise is impeded. Besides, this may lead to reduced training efficiency or even muscle loss due to low blood sugar.
Bananas are known as the optimal tonic among fruits as it contains lots of carbohydrates and adequate sugar that furnish the energy you need before exercise and supplement the glucose you have consumed in training.
They are also rich in vitamins and minerals, including potassium ions important for muscle contraction, magnesium ions critical for energy conversion, vitamin B6 helpful to protein metabolism, vitamin C necessary for hormone synthesis, etc. Generally speaking, bananas are of great nutritional value.
The most worthy point is that the fruit is fairly available and affordable. It is recommended that you eat 1-2 bananas half an hour before exercise as reserved energy to be consumed later, and eat one immediately after exercise. By doing so, your muscles can quickly get supplemented with the lost sugar to improve exercising efficiency.
The ideal pre-training diet should include protein foods that are easy to digest and absorb, as well as slow-digesting carbohydrates such as fruit, oatmeal, or whole wheat bread. It would be better to eat these foods 1 hour before training. (You can also add a handful of nuts, such as peanuts and almonds) Such a combination enhances your physical strength in training and facilitates the recovery and growth of muscles. Slow-digesting carbohydrates also help in maintaining a low insulin level, thereby ensuring the fat-burning process is not hindered.
