The following is the experience of netizens, for your reference.
First day
0830 Woke up for a cup of coffee, and took another cup to go out.
1600 I was a little hungry at first, but I was overwhelmed by drinking a little more water.
2000 I feel my head is chaotic, and I am in a bad mood. After soaking in salt water and drinking it, it is better. It should be because of unstable blood sodium. Then I took vitamins and calcium powder.
2230 I wanted to sleep, so I lay down for an hour. I don't know if I was tired or something. After taking a shower, I lost one kilogram of weight, but most of it should be water? Although I drink a lot of water throughout the day.
The next day
0400 My stomach keeps grunting, but I don't want to eat very much (hunger and appetite are two different things!), eat a pack of probiotics before going to bed.
1030 Wake up and feel good, but I have symptoms of low blood pressure. Do some simple exercises (plank support, aerial cycling, yoga stretching, etc.).
1200 drank a cup of coffee.
1430 Observed the body while changing clothes, because the stomach disappeared obviously without food, and the skin looked pale. His head is a little dizzy, he is walking and his stomach is empty, but he still has little appetite. I ate a vitamin before going out and soaked in sea salt lemonade. I hope I don’t pass out during the closing class today. Haha
2300 I got off work alive and drank a little sea salt lemonade when I was uncomfortable, but I was still tired and unhappy. Going to sing with friends later should start eating, so this fast is about 48 hours.
In conclusion
I have the habit of fasting at 8-16. I tried 6-18 or 4-20 a while ago, so you should measure your physical condition before trying!
In fact, this fast is very temporary
I originally wanted to challenge 72 hours at a time, but I was too hasty. It might be 60 next week and 72 next week. Successful update next week
