Well, when I cook it myself, I change it to a cucumber in the morning, a cucumber with an egg or just an egg at noon, and I don't eat it at night. Play badminton for half an hour to an hour at five or six in the afternoon. Go to bed at about ten o'clock every night and get up early in the morning. Well, also, first thing in the morning, drink a large glass of warm water, about 600ML. Drink two liters of water every day!
Come on! As long as you have perseverance, you can do it!
However, in the end, it will cause great harm to the body and take time. In fact, if you are not too fat, just control your diet and exercise more every day! Health is the most important!
