I am a fat man. I eat everything fat and have a strong mouth. I am the legendary fat man who drinks cold water and grows meat. Later, I made up my mind to drink cold water and drink hot water when I gain weight. If you eat less, don't eat at all. For half a month, fifteen days, two kilograms of water a day, a cup of honey water in the morning, and twenty kilograms of nothing for half a month.
