I'm not informed on this topic - but isn't this dangerous? I mean, if your numbers are correct, an average adult loses 6% of their bodyweight doing this over 5

  It's practically impossible that that is all body fat. 1kg is over 7000 calories. The body is more than 50% water, so weight is highly variable based on water retention, and fasting causes the body to excrete a lot of water. For one, no salt intake will cause you to lose water. Secondly, glycogen depletion also causes you to lose water. The metallic taste in the mouth is ketosis, proof of glycogen depletion.

  I used to do it on and off for a year or more 15 years ago. I did it just for fun but noticed significantly improved productivity during the week. I too would drink juice in the morning and possibly juice or 2 sugarcubes at lunch but not always and no calories otherwise. To ease into fasting I would start by skipping dinner. Skipping breakfast was then easy (for me at least) and the rest of the week was no problem. Then during a boring week in the military I decided to test what I had heard that we have 80% left when we feel completely exhausted. So after a couple of days of my "normal" fasting (IIRC) I skipped even my breakfast juice and continued without. Later that day I went to the gym and started lifting weights. 15 minutes into that I was completely drained and I was shaking for hours afterwards (again IIRC). That was my last time. :-/ I want to try again, but with a family it is way harder (and that experience kind of scared me.)
