I averaged 1.3 lbs/day for the entire length of my 60 day fast, and the first two weeks were much higher weight loss than usual. I can see 18kg in 18 days depending on what size you are. Of course 2-4kg will be water weight and another 2-4kg will just be stuff that lives in your gut, which is to say you'll gain it right back when you start eating again.
I just rolled into day four of a fast and the delta from two days ago is 3.72 kg.
Most of the weight you lose in the first 3 to 5 days of a fast isn't fat, its stuff in your gut and losing water as you draw down your glycogen stores.
So the water I was drinking I added a pinch of salt to it so I was drinking salty water. Obviously that will increase the Th17 cells but the number of immune cells drop off when you dont eat because generally the immune system attacks some of the food we eat, starch is one of the sugar's it wont attack.
