Please come in and answer some questions about losing weight with experienced friends.
Similar to running, I think it will rebound, and I may not be able to persist. I think a walk might suit you. You can take a walk after dinner. I suggest you eat apples for dinner. You'd better eat apples only two days a week. You can eat them until you are full when you are hungry, and then you can walk for half an hour. After a month, the weight loss effect will be obvious.
