Do you mind sharing some of the side-effects you experienced as well as your goal overall for the 21 day fast? Mostly curious about weight/mass loss numbers but also any adverse bodily reactions.
For the first 2-3 days I was hungry - after that I was fine.
For the remainder:
I felt tired, cranky, cold (especially at night), and on occasion I would have trouble getting to sleep. My inflammation was markedly decreased. I have dermatographia (skin writing) where I can use my fingernail to draw a line on my arm (for example) and within a couple of minutes it will swell up like an allergic reaction. After about 5 minutes it goes away. I tried doing this halfway into my fast and while the inflammation was still there, it was much much much less noticeable (and not puffed up.)
As far as overall goal, aside from losing some weight was trying to reset my immune system which has been out of sorts for the past couple of years. I've been through a battery of tests to figure out why I've been feeling less than normal (brain fog, neuropathy, etc.) for the past 2-3 years and I was hoping it would help. Alas it did not. I lost 31lb and gained about half of it back after a couple of months. I wasn't following any particular diet after the fast, particularly because when I experience these bouts of brain fog/malaise, I don't feel motivated to stay on track.
I've started walking 5-7 miles a day and exercising over the past couple of months and have noticed some improvement. I did a 3 day water fast a few weeks ago, who knows if that was a factor. I'm maybe 85% of the old me, which is a massive improvement from where I was coming from. Hopefully things continue to improve (or simply doesn't get worse.)
