The method of losing weight seemed strange in some ways, even illogical. Although you could increase the consumption of energy and reduce weigh to lose weight by running, the weight was not reduced and was increased instead. There were some reasons below. First, the more exercises you did, and the more food you ate. Some people lost weight at the beginning of running, then the weight was rose again after persisting for some time. This was because running could not only consume the energy, but also stimulate the digestive organs and increase the appetite. At the beginning of running, it could also control the diet and lose weight. For some time, due to the unbearable hunger and the thrill of reducing weight was over, the diet was increased and the weight was gained. Second, you could not sustain. Some people lost the interest and stopped the movement after a period of running. You should understand that the transformation of the digestive system was slower than the motor system, the consumption of the energy was reduced significantly after suspending running, yet the function of the gastrointestinal absorption was still robust. Therefore you would gain weight. Yet the research showed that running did not improve the appetite of a person. Conversely, it could usually make you lose the appetite. A research fellow said that, exercise might be an inhibitor of the appetite rather than the stimulant. Running was a way to suppress the appetite. The inhibition of appetite usually continued for a few hours after doing the exercises, and only wanted to eat some fruits, because they contained more water and it was not easy to fill the stomach. If you wanted to be thin, you could run. You did not worry about that you would eat more after doing exercises and gained weight, because running could suspend the appetite. This phenomenon could be proven by the animal studies: The animals who did not exercise would eat more compared with the animals who did exercises one hour a day.
It was also surprising that the speed of running did not have effect on the consumption of the calories. It took a person whose weight was one hundred and fifty pounds eight minute to consume one hundred and two calories by running, and the same people who ran one mile in twelve minutes would spend ninety-eight calories. Some researches also showed that, the length of your leg or your step had less effect on the consumption of the calories. Even you were a world-class runner, or just a person who started running, it still did not matter. The mechanical effect of the athlete was slightly higher than that of the people who began to run. If you ran a mile in eight minute and consumed one hundred and twenty-four calories, in this way to calculate, the consumption of the calories was six hundred and twenty when you ran five miles. The body needs to absorb three thousand and five hundred calories to increase a pound and to consume three thousand and five hundred calories to lose a pound. So, in a month, your weight would be lost by about five pounds on the basis of the speed of your running.
