I saw it on the road to health. I am an authority. Three people talked about the period of colds and tumors. The teacher who came back from America said that he had lost 20 pounds in three months. He said to eat less meat, and he stopped eating after eight o'clock in the evening. There is also walking fast every day, preferably 10000 steps.
There is also "Walking with Action", which is also mentioned in "The Road to Health". I walked three small circles and my stomach hurt the next day. Obviously, I don't usually exercise. You can walk alternately in two ways.
The action is like this: walk slowly, the steps must be big, the palms of both hands are down, the swing range is large, and it is shoulder-length, which is equivalent to drawing 90 degrees. Girls 100 meters walk 1 10 steps, boys 100 meters walk 100 steps.
