First of all, we should observe our living habits and see what needs to be adjusted and corrected. For example, I used to have the habit of overeating and I was very picky about food. Love to eat fried food. Correct these unhealthy habits and move on to the next step. I have a light and regular diet now. Eat seven minutes full, and basically don't eat after eight o'clock in the evening.
Step by step, starting with the simple and easy. It is good for your health to recuperate slowly. I don't know if losing weight for seven months, healthy living habits and reasonable exercise are feasible. I also lost 20 kilograms in half a year.
