In addition to diet control, exercise is also essential during weight loss. At that time, my main exercise was walking fast and sometimes skipping rope. Walking fast usually takes six or seven kilometers a day, which takes an hour. In that case, skipping rope usually jumps 1000. I lost 13 kg in ten days by controlling diet and exercise. Then I lost weight intermittently for three or four months, from 145 kg to 1 15 kg, and lost 30 kg.
