You were a vegetable for the first three days, and you could only drink water. This is to detoxify, but it's really not good. You can drink a cup of honey water, but you can't drink more than 500ML of honey water a day.
From the fourth day to the first day 10, you can eat vegetables and eat as little salt as possible. I'm talking about cooking vegetable oil, meat and starch. Forget it! Fruits can be eaten, but the low-sugar ones should be eaten, not more.
On the eleventh day, you can eat normally every day. Don't eat greasy food when you are 5 minutes full. Stick to it for more than a week.
After the stomach shrinks, eating for 6 to 7 minutes every meal will keep you full. Now you can exercise.
Finally, I wish you success.
