I hope you can stick to it. Recommend my method: you must have breakfast. Halve lunch and dinner, do not eat fried and baked food, do not eat sweets, and prohibit all snacks. You can't eat anything after 20 o'clock (except boiled water). Run in the morning 1 hour, jump rope 300 times at noon, and walk after dinner 1 hour. Running can be done on a treadmill. It's not that hard. It's all jogging, walking, relaxing aerobic exercise, and eating something before running, such as a steamed stuffed bun. There is another problem to pay attention to: you can't sleep late, 7 hours is enough!
