In the morning, the level of human insulin glargine is low, and insulin glargine plays a role in inhibiting fat dissolution. When the level of insulin glargine is low, aerobic exercise will ignore the actual effect of inhibition and let aerobic exercise dissolve other fats. After a night's sleep, the glycogen storage and water content of the body will be relatively low.
During aerobic exercise, the body tends to use stored fat as kinetic energy to supply energy. In fact, this idea of lianzhong game has been applied by several direct evidences. If your body consumes sugars and carbohydrates stored in your body during aerobic exercise, then your body will use carbohydrates as a natural substance instead of fat. In the 20th century, biologists made a very interesting experiment.
All the subjects did aerobic exercise with low compressive strength for four hours, but one group ingested 200 grams of glucose water in 90 minutes, and then the body improved the dissolution of glucose powder, while the rest of the subjects used more and more fat in aerobic exercise, which convinced many people that they wanted to consume as much fat as possible in aerobic exercise and should prevent carbohydrate intake before or during the whole process.
In one experiment, 20 young women were divided into fasting aerobic group, and they ate the same macroeconomic nutrients. According to the classification decision, they also did aerobic exercise for one hour after meals on an empty stomach, three times a week, one hour each time, and the calorie value was reduced by 500 calories. After four weeks, both groups lost fat, but there was no difference in weight loss.
This means that the actual effect of aerobic exercise on an empty stomach is the same as that after meals, but the target population of the experiment is small and the delay time is short, so we can't fully believe it. There is no strong evidence that all methods are more aerobic.
In this way, it seems that there is no special benefit of fasting aerobic. In fact, the actual effect of losing weight lies in reducing calorie intake to some extent. Some people who like to do aerobic exercise in the morning are not necessarily trying to lose weight better, but may be trying to make their day more full, or they may have no appetite, just to better enhance their appetite.
Therefore, the most important thing for aerobic exercise is to allocate it at the right time, give full play to its actual effect, and choose to do aerobic exercise in the process of your full experience, whether before or after meals.
The above is my answer, for your reference, hoping to help you.
