If you follow the coach's plan, you can definitely reduce it. He will analyze it according to your physical condition.

I ran without a coach, and I lost 40 pounds.

I didn't go on a diet and jump rope every day for the first two months, but if I did, it would only take an hour. At that time, it was very slow, and it took only two months to lose weight 12 kg.

Then I started running in the gym in the third month, running for more than an hour every day. 72.5 kg before running, now 58.2 kg. I started running on July 9, and it's less than three months today. I didn't do any other sports. I just care about my food. I put very little cooking oil and salt. Eat more apples. In a word, the cooking method of vegetables is very important. For example, if you put a pile of oil in a dish of vegetables, the calories are not lower than the fat.
