Jog for an hour every day, preferably at night. Running is very important. If you run for two hours today and don't run tomorrow, it won't work at all. Also, if it rains, use other sports instead. Anyway, the premise is that you keep exercising.
Losing weight is a painful and long process. Persistence is the most important thing. Many people give up after a few days. This is the least desirable. Another thing is, don't worry.
Finally, I wish you success in losing weight!
