I'll tell you about the operation. Exercise+diet. That's how I lost weight. I have to eat in the morning. You can eat more and have a full stomach at 8 noon. Do not eat vegetable rice at night. You can climb mountains in the morning, swim at noon, squat in the afternoon and take a walk at night. Do this every day, you can lose 5 to 7 pounds a month. I am so thin. It was all me. Please accept it.
