First, adhere to the normal three meals a day, be sure to be picky about food, eat no fat at all, only lean meat;
Second, exercise your brain every day. If you can exercise in your dreams, the effect will be better.
Third, regular outdoor long-distance running every day, not in the gym and indoors;
Fourth, if you have time, you can sleep backwards during the day and night, find a noisy place to sleep during the day, or don't sleep for n hours without affecting others.
My dream is to be a fat man, but unfortunately my weight has remained at 108 kg for ten years. Wish you success!
Please adopt it. Thank you!
