I am a fat person, how can I lose weight quickly?

In addition to diet control, exercise is also essential during weight loss. The exercise I took at that time was mainly brisk walking, and sometimes skipping rope. I usually walk briskly for six or seven kilometers every day and it takes about an hour. I usually jump rope for 1,000 times. I lost 13 pounds in ten days using this method of diet and exercise. Later I lost weight off and on for three or four months, from 145 pounds to 115 pounds, a total of 30 pounds in one day.
