You’d Better Eat a Banana before Morning Fitness
Q: I recently fall in love with morning exercise, every morning after I wake up and drink a glass of water, I will come to the district to exercise, and I feel it consuming 
fat very well, each time I finish the exercise, I feel body empty and legs shaking. What’s more, I particularly like to eat something. Is there any way to alleviate this situation?
Dr. Li Weidong, professor of U.S. Health and Sports Science University of Memphis assistant answers: For a person who likes the morning exercise very much, he must eat something easier to digest, such as bananas, raisins and sports drinks with high carbohydrate. And exercise after 30 minutes. Do not eat foods contained fat and protein, because these foods are not easy to digest.
Single - carbohydrate foods are easy to digest such as syrup, orange juice, but it can cause sudden blood sugar rising and dropping, which can make you feel tired. So, do not drink sugar water, honey and so on.
Fasting exercise will lead to dizziness and vomiting, appearing the “exercise-induced low blood sugar”, or even syncope; while exercise immediately after eating can cause stomach pains, and even vomiting. If you exercise an hour after you wake up, you must eat food that contains 200-300 kcal of energy.
Friends who want to lose weight may think that fasting exercise after getting up on the morning can directly call up the body fat, because after a night of digestion and absorption, the blood glucose is low. Now, I tell you, this argument is wrong. the body is always first call carbohydrates for energy, and the first is blood sugar, if the blood glucose is too low, the body can not be timely for the energy, it will produce syncope, and significantly reduce the intensity of exercise, so as to not reach the training purposes. On the contrast, eat a banana and carbohydrate before exercise at an appropriate time, body fat monitor on the one hand, it can ensure adequate supply of blood sugar, on the other hand, the decomposition of sugar can promote fat burning. In other words, it is an efficient way of exercise, which can mobilize the sleeping body fat to make them efficient combustion. And in this way it can achieve weight loss goals.
